TL;DR: Results demonstrate a decrease in odds of mortality for the undifferentiated trauma patient when response-time or transfer-time are shorter and increased on-scene time and total prehospital time are associated with increased odds of survival for this population.
Abstract: Objective Time is considered an essential determinant in the initial care of trauma patients. Salient tenet of trauma care is the ‘golden hour’, the immediate time after injury when resuscitation and stabilization are perceived to be most beneficial. Several prehospital strategies exist regarding time and transport of trauma patients. Literature shows little empirical knowledge on the exact influence of prehospital times on trauma patient outcome. The objective of this study was to systematically review the correlation between prehospital time intervals and the outcome of trauma patients. Methods A systematic review was performed in MEDLINE, Embase and the Cochrane Library from inception to May 19th, 2014. Studies reporting on prehospital time intervals for emergency medical services (EMS), outcome parameters and potential confounders for trauma patients were included. Two reviewers collected data and assessed the outcomes and risk of bias using the STROBE-tool. The primary outcome was the influence on mortality. Results Twenty level III-evidence articles were considered eligible for this systematic review. Results demonstrate a decrease in odds of mortality for the undifferentiated trauma patient when response-time or transfer-time are shorter. On the contrary increased on-scene time and total prehospital time are associated with increased odds of survival for this population. Nevertheless rapid transport does seem beneficial for patients suffering penetrating trauma, in particular hypotensive penetratingly injured patients and patients with a traumatic brain injury. Conclusion Swift transport is beneficial for patients suffering neurotrauma and the haemodynamically unstable penetratingly injured patient. For haemodynamically stable undifferentiated trauma patients, increased on-scene-time and total prehospital time does not increase odds of mortality. For undifferentiated trauma patients, focus should be on the type of care delivered prehospital and not on rapid transport.

TL;DR: The results of this analysis demonstrate that the incidence of complications experienced by young femoral neck fracture patients is relatively high, and AVN and nonunion were the most common complications that likely contributed to repeat surgeries.
Abstract: Background Femoral neck fractures in patients 60 years of age or younger are challenging injuries to treat because of the high-energy trauma mechanisms and the displaced fracture patterns typically found in this patient population. Understanding the burden of disease is an important first step in addressing treatment controversies in this population. The purpose of the current study is to quantitatively pool the incidence of patient important complications following internal fixation of young femoral neck fractures. Methods A comprehensive search of the Medline, Embase, CINAHL, Cochrane Database of Systematic Reviews, and Central databases was completed under the direction of a biomedical librarian. Multiple outcomes of interest (complications) were collected and included: reoperation, femoral head avascular necrosis, fracture non-union, infection, implant failure, and malunion. Results 1558 fractures from 41 studies were included in the meta-analysis. An18.0% pooled reoperation incidence was observed for isolated femoral neck fractures. The total pooled incidence of avascular necrosis (AVN) was 14.3%, and the total incidence of nonunion was 9.3%. When stratified for fracture displacement displaced fractures were more likely to undergo reoperation and to result in AVN or non-union. The total incidence of malunion was 7.1%, implant failure was 9.7%, and surgical site infection was 5.1%. Complications associated with a femoral neck fracture treated in conjunction with an ipsilateral femoral shaft fracture were lower overall than the pooled estimates for isolated neck fractures. Conclusions The results of our analysis demonstrate that the incidence of complications experienced by young femoral neck fracture patients is relatively high. Reoperation following internal fixation of isolated femoral neck fractures occurred in nearly 20% of cases, and AVN and nonunion were the most common complications that likely contributed to repeat surgeries. These results highlight the importance of further efforts to improve the clinical outcomes in this population.

TL;DR: Clinicians should take in to account these findings when managing patients with long bone fractures, particularly the femur and tibia in order to minimise the risk of non-union.
Abstract: Non-union continues to be the most devastating complication after fracture fixation. Its treatment can be prolonged and often unpredictable. The burden to the patient, surgeon and health care system can be immense. Strategies to prevent it and or identify early its development are desirable in order to improve the clinical course of the affected patients and their outcomes. We undertook a systematic review of the literature in order to identify the most common and important risk factors based on the hierarchy of level of evidence. Accordingly, a stratification scale was formed which highlighted 10 risk factors including; an open method of fracture reduction, open fracture, presence of post-surgical fracture gap, smoking, infection, wedge or comminuted types of fracture, high degree of initial fracture displacement, lack of adequate mechanical stability provided by the implant used, fracture location in the poor zone of vascularity of the affected bone, and the presence of the fracture in the tibia. Clinicians should take in to account these findings when managing patients with long bone fractures, particularly the femur and tibia in order to minimise the risk of non-union.

TL;DR: The distribution among genders shows that males present a higher frequency of fractures while participating in sports activities and walking, and women present the highest frequency while walking and during indoor activities.
Abstract: Introduction The literature lacks recent population-based epidemiology studies of the incidence, trauma mechanism and fracture classification of tibial shaft fractures. The purpose of this study was to provide up-to-date information on the incidence of tibial shaft fractures in a large and complete population and report the distribution of fracture classification, trauma mechanism and patient baseline demographics. Methods Retrospective reviews of clinical and radiological records. Results A total of 196 patients were treated for 198 tibial shaft fractures in the years 2009 and 2010. The mean age at time of fracture was 38.5 (21.2SD) years. The incidence of tibial shaft fracture was 16.9/100,000/year. Males have the highest incidence of 21.5/100,000/year and present with the highest frequency between the age of 10 and 20, whereas women have a frequency of 12.3/100,000/year and have the highest frequency between the age of 30 and 40. AO-type 42-A1 was the most common fracture type, representing 34% of all tibial shaft fractures. The majority of tibial shaft fractures occur during walking, indoor activity and sports. The distribution among genders shows that males present a higher frequency of fractures while participating in sports activities and walking. Women present the highest frequency of fractures while walking and during indoor activities. Conclusion This study shows an incidence of 16.9/100,000/year for tibial shaft fractures. AO-type 42-A1 was the most common fracture type, representing 34% of all tibial shaft fractures.

TL;DR: Syndesmotic screw and TightRope had similar postoperative malreduction rates and functional outcomes and quality of life showed no significant difference between groups, but the incidence of ankle joint osteoarthritis nor functional outcome significantly differed between the fixation methods.
Abstract: Background The accuracy and maintenance of syndesmosis reduction are essential when treating ankle fractures with accompanying syndesmosis injuries. The primary aim of this study was to compare syndesmosis screw and TightRope fixation in terms of accuracy and maintenance of syndesmosis reduction using bilateral computed tomography (CT). Study design Single centre, prospective randomised controlled clinical trial; Level of evidence 1. Methods This study (ClinicalTrials.gov, NCT01742650) compared fixation with TightRope ® (Arthrex, Naples, FL, USA) or with one 3.5-mm tricortical trans-syndesmotic screw in terms of accuracy and maintenance of syndesmosis reduction in Lauge-Hansen pronation external rotation, Weber C-type ankle fractures with associated syndesmosis injury. Twenty-one patients were randomised to TightRope fixation and 22 to syndesmotic screw fixation. Syndesmosis reduction was assessed using bilateral CT intraoperatively or postoperatively, and also at least 2 years after surgery. Functional outcomes and quality of life were assessed using the Olerud–Molander score, a 100-mm Visual Analogue Scale, the Foot and Ankle Outcome Score, and the RAND 36-Item Health Survey. Grade of osteoarthritis was qualified with follow-up cone-beam CT. Results According to surgeons’ assessment from intraoperative CT, screw fixation resulted in syndesmosis malreduction in one case whereas seven syndesmosis were considered malreduced when TightRope was used. However, open exploration and postoperative CT of these seven cases revealed that syndesmosis was well reduced if the ankle was supported at 90˚. Retrospective analysis of the intra- and post-operative CT by a radiologist showed that one patient in each group had incongruent syndesmosis. Follow-up CT identified three patients with malreduced syndesmosis in the syndesmotic screw fixation group, whereas malreduction was seen in one patient in the TightRope group ( P = 0.33). Functional scores and the incidence of osteoarthritis showed no significant difference between groups. Conclusion Syndesmotic screw and TightRope had similar postoperative malreduction rates. However, intraoperative CT scanning of ankles with TightRope fixation was misleading due to dynamic nature of the fixation. After at least 2 years of follow-up, malreduction rates may slightly increase when using trans-syndesmotic screw fixation, but reduction was well maintained when fixed with TightRope. Neither the incidence of ankle joint osteoarthritis nor functional outcome significantly differed between the fixation methods.

TL;DR: The Nottingham Hip Fracture Score shows most promising results, with reasonable discrimination and extensive validation in earlier studies, and additional research is needed to examine recalibration and to determine the best risk model for predicting early mortality following hip fracture surgery.
Abstract: Introduction While predictors for mortality after hip fracture surgery have been widely studied, research regarding risk prediction models is limited. Risk models can predict mortality for individual patients, provide insight in prognosis, and be valuable in surgical audits. Existing models have not been validated independently. The purpose of this study is to evaluate the performance of existing risk models for predicting 30-day mortality following hip fracture surgery. Patients and methods In this retrospective study, all consecutive hip fracture patients admitted between 2004 and 2010 were included. Predicted mortality was calculated for individual patients and compared to the observed outcome. The discriminative performance of the models was assessed using the area under the receiver operating characteristic curve (AUC). Calibration was analysed with the Hosmer–Lemeshow goodness-of-fit test. Results A literature search yielded six risk prediction models: the Charlson Comorbidity Index (CCI), Orthopaedic Physiologic and Operative Severity Score for the enUmeration of Mortality and Morbidity (O-POSSUM), Estimation of Physiologic Ability and Surgical Stress (E-PASS), a risk model by Jiang et al., the Nottingham Hip Fracture Score (NHFS), and a model by Holt et al. The latter three models were specifically designed for the hip fracture population. All models except the O-POSSUM achieved an AUC greater than 0.70, demonstrating acceptable discriminative power. The score by Jiang et al. performed best with an AUC of 0.78, this was however not significantly different from the NHFS (0.77) or the model by Holt et al. (0.76). When applying the Hosmer–Lemeshow goodness-of-fit test, the model by Holt et al., the NHFS and the model by Jiang et al. showed a significant lack of fit (p Discussion None of the existing models yielded excellent discrimination (AUC > 0.80). The best discrimination was demonstrated by the models designed for the hip fracture population, however, they had a lack of fit. The NHFS shows most promising results, with reasonable discrimination and extensive validation in earlier studies. Additional research is needed to examine recalibration and to determine the best risk model for predicting early mortality following hip fracture surgery.

TL;DR: Current strategies and practical tips for local application of antibiotics in orthopaedic trauma are reviewed and delivery vehicles, types of antibiotics, dosage recommendations when mixed with PMMA and indications are focused on.
Abstract: The use of local antibiotics for the prevention of infection in the setting of open fractures and as part of the treatment of osteomyelitis is well established Antibiotics are most commonly incorporated into polymethylmethacrylate (PMMA) cement, which can then be formed into beads, moulded to fit a bone defect or used to coat a guide wire or IM nail Newer delivery vehicles and techniques are being evaluated to improve upon these methods Many factors influence how local antibiotics are applied Treatment strategies are challenging to standardise due to the variability of clinical presentations The presence of hardware, upper versus lower extremity, healed versus non-healed fracture and quality of soft tissues overlying the affected bone, as well as patients' comorbidities all need to be considered Despite the accepted use of local antibiotic therapy in orthopaedic trauma, high-quality evidence regarding the use of local antibiotics is lacking Indications, techniques, dosages, types of antibiotics, elution properties and pharmacokinetics are poorly defined in the clinical setting The purpose of our manuscript is to review current strategies and provide practical tips for local application of antibiotics in orthopaedic trauma We focus on delivery vehicles, types of antibiotics, dosage recommendations when mixed with PMMA and indications

TL;DR: A significant reduction in quality of life is demonstrated for rib fracture patients requiring admission to hospital, which does not return to the level of Australian norms for at least two years.
Abstract: Introduction Rib fractures are a common injury presenting to major trauma centres and community hospitals. Aside from the acute impact of rib fracture injury, longer-term morbidity of pain, disability and deformity have been described. Despite this, the mainstay of management for the vast majority of rib fracture injuries remains supportive only with analgesia and where required respiratory support. This study aimed to document the long-term quality of life in a cohort of major trauma patients with rib fracture injury over 24 months. Methods Retrospective review (July 2006–July 2011) of 397 major trauma patients admitted to The Alfred Hospital with rib fractures and not treated with operative rib fixation. The main outcome measures were quality of life over 24 months post injury assessed using the Glasgow Outcome Scale Extended and SF12 health assessment forms and a pain questionnaire. Results Assessment over 24 months of major trauma patients with multiple rib fractures demonstrated significantly lower quality of life compared with published Australian norms at all time points measured. Return to work rates were poor with only 71% of those who were working prior to their accident, returning to any work. Conclusions This study demonstrates a significant reduction in quality of life for rib fracture patients requiring admission to hospital, which does not return to the level of Australian norms for at least two years.

TL;DR: It is indicated that GOSE, although clinically relevant, fails to capture the subjective perspective of TBI patients, which endorses the use of HRQL as valuable addition to established instruments in assessing disability following TBI.
Abstract: Background The Glasgow Outcome Scale Extended (GOSE) is the established functional outcome scale to assess disability following traumatic brain injury (TBI), however does not capture the patient's subjective perspective. Health-related quality of life (HRQL) does capture the individual's perception of disability after TBI, and has therefore been recognized as an important outcome in TBI. In contrast to GOSE, HRQL enables comparison of health outcome across various disease states and with healthy individuals. We aimed to assess functional outcome, HRQL, recovery, and predictors of 6 and 12-month outcome in a comprehensive sample of patients with mild, moderate or severe TBI, and to examine the relationship between functional impairment (GOSE) and HRQL. Methods A prospective cohort study was conducted among a sample of 2066 adult TBI patients who attended the emergency department (ED). GOSE was determined through questionnaires or structured interviews. Questionnaires 6 and 12 months after ED treatment included socio-demographic information and HRQL measured with Short-Form Health Survey (SF-36; reflecting physical, mental and social functioning) and Perceived Quality of Life Scale (PQoL; measuring degree of satisfaction with functioning). Results 996 TBI survivors with mild, moderate or severe TBI completed the 6-month questionnaire. Functional outcome and HRQL after moderate or severe TBI was significantly lower than after mild TBI. Patients with moderate TBI showed greatest improvement. After one year, the mild TBI group reached outcomes comparable to population norms. TBI of all severities highly affected SF-36 domains physical and social functioning, and physical and emotional role functioning. GOSE scores were highly related to all SF-36 domains and PQoL scores. Female gender, older age, co-morbidity and high ISS were strongest independent predictors of decreased HRQL at 6 and 12 months after TBI. Conclusions HRQL and recovery patterns differ for mild, moderate and severe TBI. This study indicates that GOSE, although clinically relevant, fails to capture the subjective perspective of TBI patients, which endorses the use of HRQL as valuable addition to established instruments in assessing disability following TBI. Influence of TBI severity on recovery, together with female gender, older age, co-morbidity and high ISS should be considered in long-term follow-up and intervention programs.

TL;DR: The biomechanical properties of the hip are described and the most commonly used devices compared and Experimental evidence suggests that in Pauwels type III fracture patterns a cephalomedullary nail was significantly stronger in axial loading.
Abstract: Femoral neck fractures represent a relatively uncommon injury in the non-elderly population often resulting from high-energy trauma. The cornerstone of their management is anatomic reduction and stable internal fixation of the femoral neck in an attempt to salvage the femoral head. Complications including avascular necrosis of the femoral head, non-union and post-traumatic osteoarthritis are not uncommon. The clinical outcomes of these patients can be improved with good pre-operative planning, optimization of surgical procedures and introduction of new improved implants and techniques. In the herein study, we attempt to describe the biomechanical properties of the hip and compare the performance of the most commonly used devices. Experimental evidence suggests that in Pauwels type III fracture patterns a cephalomedullary nail was significantly stronger in axial loading. Moreover, in unstable basicervical patterns cannulated screws (triangular configuration) demonstrated a lower ultimate load to failure, whereas in subcapital or transervical patterns both the cannulated screws (triangular configuration) and the sliding hip screw demonstrated no compromise in fixation strength. The fracture pattern appears to be the major determinant of the ideal type of implant to be selected. For a successful outcome each patient needs to be considered on an individual basis taking into account all patient and implant related factors.
TL;DR: The univariate regression analysis showed that the nature of complications after tibial shaft nailing could be multifactorial, and future strategies should focus on prevention in high-risk populations such as polytrauma patients treated with EF.
Abstract: Introduction Despite modern advances in the treatment of tibial shaft fractures, complications including nonunion, malunion, and infection remain relatively frequent. A better understanding of these injuries and its complications could lead to prevention rather than treatment strategies. A retrospective study was performed to identify risk factors for deep infection and compromised fracture healing after intramedullary nailing (IMN) of tibial shaft fractures. Materials and methods Between January 2000 and January 2012, 480 consecutive patients with 486 tibial shaft fractures were enrolled in the study. Statistical analysis was performed to determine predictors of deep infection and compromised fracture healing. Compromised fracture healing was subdivided in delayed union and nonunion. The following independent variables were selected for analysis: age, sex, smoking, obesity, diabetes, American Society of Anaesthesiologists (ASA) classification, polytrauma, fracture type, open fractures, Gustilo type, primary external fixation (EF), time to nailing (TTN) and reaming. As primary statistical evaluation we performed a univariate analysis, followed by a multiple logistic regression model. Results Univariate regression analysis revealed similar risk factors for delayed union and nonunion, including fracture type, open fractures and Gustilo type. Factors affecting the occurrence of deep infection in this model were primary EF, a prolonged TTN, open fractures and Gustilo type. Multiple logistic regression analysis revealed polytrauma as the single risk factor for nonunion. With respect to delayed union, no risk factors could be identified. In the same statistical model, deep infection was correlated with primary EF. Conclusions The purpose of this study was to evaluate risk factors of poor outcome after IMN of tibial shaft fractures. The univariate regression analysis showed that the nature of complications after tibial shaft nailing could be multifactorial. This was not confirmed in a multiple logistic regression model, which only revealed polytrauma and primary EF as risk factors for nonunion and deep infection, respectively. Future strategies should focus on prevention in high-risk populations such as polytrauma patients treated with EF.
TL;DR: There is an equal divide in preference between multiple screws and the SHS for displaced fractures, which contradicts previous survey and small trial data recommending multiple screws for all fracture patterns.
Abstract: Background Femoral neck fractures in young adults (ages Methods A 17-item survey was developed and tested for validity and reliability prior to administration. The questionnaire characterised surgeon demographics, treatment preferences for displaced and undisplaced fractures, and controversies for future clinical trials. The target population consisted of surgeons from the Canadian Orthopaedic Association, the Orthopaedic Trauma Association, and attendees at an international fracture course. Results 540 surgeons completed the survey, exceeding our sample size requirement. There was a similar proportion of respondents from academic and community hospitals. Most surgeons (61%) treat 1–5 young adult femoral neck fractures per year. For undisplaced fractures, 78% of respondents prefer to use multiple cannulated screws. For displaced fractures, equal preference for multiple screws (46%) and the sliding hip screw (SHS, 49%) was reported. The majority of surgeons perform an open reduction in less than 25% of cases, and the time to fixation was typically between 8 and 24 h. Conclusions Multiple cannulated screws remain the preferred treatment for most surgeons treating undisplaced fractures; however, there is an equal divide in preference between multiple screws and the SHS for displaced fractures. This increased preference for the SHS contradicts previous survey and small trial data recommending multiple screws for all fracture patterns. The lack of surgeon consensus and the high rates of fracture complications associated with fixation of young femoral neck fractures supports the need for definitive clinical trials to optimise patient important outcomes.
TL;DR: The study showed that the 'diamond concept' is a suitable method for safely and effectively treating non-unions with large defects or infections and the use of an antibiotic-coated nail provides a therapeutic benefit.
Abstract: Background The successful treatment of atrophic tibia non-unions and tibia non-unions with large bone defects or infections is a major challenge in orthopedic and trauma surgery. This article evaluates the use of the ‘diamond concept’ using a one-step or two-step procedure according to ‘Masquelet technique’ in the treatment of atrophic tibia non-unions. Methods Between February 2010 and March 2014, 102 patients with atrophic non-unions were treated according to the ‘diamond concept’ in our center. Ninety-nine were available for follow-up. Forty-nine received a one-step treatment (Group 1, G1) and 50 patients received a two-step treatment according to the ‘Masquelet technique’ (Group 2, G2). Clinical and radiological parameters were measured preoperatively as well as 4, 6, and 12 weeks and 6 and 12 months postoperatively. In order to evaluate the subjective health of patients, we used the SF-12 questionnaire. Data analysis was performed one year after treatment. Results The rate of consolidation in G1 was 84% and 80% in G2. The time to heal in G2 was 8.6 ± 2.9 months, which is significantly longer than in G1 being 6.9 ± 3.1 months. In comparison patients in G1/G2 had an average of 3.2/6.7 previous major surgeries. In G1, 4 of 8 patients who did not heal successfully showed positive intraoperative cultures. In G2, 26 patients (52%) initially presented with positive cultures. The results of the SF-12 questionnaire improved in both groups during the postoperative follow-up, but showed no significant differences between groups. In 29 patients a gentamycin-coated nail was used for reosteosynthesis. These patients showed by trend a lower rate of complications at a higher rate of consolidation. Conclusions Our study showed that the ‘diamond concept’ is a suitable method for safely and effectively treating non-unions with large defects or infections. The use of an antibiotic-coated nail provides a therapeutic benefit. For large bone defects of infected non-unions the two-step procedure after Masquelet is an efficient way to eradicate the infection and treat the bone defect successfully.
TL;DR: Conventional percutaneous iliosacral screw fixation is a successful operative treatment for elderly patients with persistent lower back pain after unstable posterior ring fractures of the pelvis, and can be regarded as a safe procedure.
Abstract: Introduction Osteoporotic posterior ring fractures of the pelvis are common injuries in the elderly, but the treatment of these fractures still remains controversial. Percutaneous iliosacral screw fixation is one surgical option if conservative treatment cannot provide sufficient pain reduction. The aim of this study is to provide short-term results of elderly patients with percutaneous screw fixation. Methods 30 patients with posterior ring fractures were treated between 12/2009 and 01/2014 with percutaneous iliosacral screw fixation. Patients’ mean age was 78.4 years. Concerning short-term outcome, we focused on initial pain level and postoperative pain reduction together with intra- and postoperative complications. Results The average hospital stay was 23.7 days, with surgical treatment performed after an average of 9.2 days. 90% of our patients were female. All 30 patients had a lower level of pain at discharge compared with admission or immediately prior to surgery. The difference in pain level at admission compared with the pain level upon discharge showed a mean reduction from 6.8 to 1.8 with a statistically significant change (P ≤ 0.001). 24 of 30 patients had no registered complications, one screw malpositioning with postoperative nerve irritation occurred. Discussion Conventional percutaneous iliosacral screw fixation is a successful operative treatment for elderly patients with persistent lower back pain after unstable posterior ring fractures of the pelvis. Intra- and postoperative complications are rare, so this treatment can be regarded as a safe procedure. Level of evidence IV (retrospective study).
TL;DR: The application of the "diamond concept" in this cohort of patients was associated with a high union rate by providing an optimal mechanical and biological environment and should be considered in the surgeon's armamentarium where difficulty of bone repair is foreseen.
Abstract: The aim of this retrospective study with prospectively documented data was to report the clinical results of treatment of long bone non-unions using the “diamond concept”. Over a 4-year period, patients that presented with a long bone non-union and were managed with the diamond conceptual framework of bone repair were evaluated. Exclusion criteria were hypertrophic, pathological, and infected non-unions. Fixation was revised as it was indicated whilst biological enhancement included the implantation of RIA graft, BMP-7 and concentrated bone marrow aspirate. Data recorded included patient demographics, initial fracture pattern and type of stabilisation, number of previous interventions, time to reoperation, time to union and functional outcome. Painless full weight bearing defined clinical union. Radiological union was defined as the presence of mature callous bridging to at least 3 bone cortices. The minimum follow up was 12 months (range 12–32). In total 64 patients (34 males) with a mean age of 45 years (17–83) were evaluated. Anatomical distribution of non-unions included the femur (54.68%), tibia (34.38%), humerus (4.68%), radius (3.13%) and clavicle (3.13%). The median number of previous interventions was 1 (range 1–5). The majority of patients (82.62%) underwent revision of fixation whereas only bone grafting was performed 9.38% of patients. Three patients developed superficial wound infection (one was MRSA), 1 had deep vein thrombosis and 1 developed heterotopic bone formation. Union was successful in 63/64 (98.4%) non-unions at a mean time of 6 months (range 3–12). All patients were mobilising pain free and returned to their daily living activities at the final follow up. The application of the “diamond concept” in this cohort of patients was associated with a high union rate by providing an optimal mechanical and biological environment. Such an approach should be considered in the surgeon's armamentarium particularly in such cases where difficulty of bone repair is foreseen.
TL;DR: In The Netherlands, symptoms of depression measured 1-2 months after musculoskeletal trauma correlate with disability 5-8 months after this trauma.
Abstract: Introduction Musculoskeletal injury is a common cause of impairment (pathophysiology), but the correlation of impairment with pain intensity and magnitude of disability is limited. Psychosocial factors explain a large proportion of the variance in disability for various orthopaedic pathologies. The aim of this study is to prospectively assess the relationship between psychological factors and magnitude of disability in a sample of orthopaedic trauma patients in The Netherlands. Material and methods One hundred and one adult patients between 1 and 2 months after one or more fractures, tendon or ligament injuries were enrolled. Four eligible patients refused to participate. Thirty-five women and 30 men with an average age of 50 years (range, 22–92 years) completed the follow-up evaluation between 5 and 8 months after their injury and their data was analyzed. The patients completed a measure of disability (the Short Musculoskeletal Function Assessment-Netherlands, SMFA-NL), the Dutch Centre for Epidemiologic Study of Depression-scale (CES-D), the Dutch Impact of Event Scale (SVL), and the Dutch Pain Catastrophizing Scale (PCS) at the time of enrollment and again 5–8 months after injury. Results There were moderate correlations between symptoms of depression (CES-D, r = 0.48, p Discussion and conclusions In The Netherlands, symptoms of depression measured 1–2 months after musculoskeletal trauma correlate with disability 5–8 months after this trauma. The psychological aspects of recovery from musculoskeletal injury merit greater attention. Level of evidence Level II, Prognostic study.
TL;DR: It is demonstrated that the distal femoral and hip fracture populations are similar, and the current disparity in their management is highlighted, showing the metrics and standards of care currently applied to hip fractures should be applied to the treatment of distal Femoral fractures.
Abstract: Background Hip fracture care has evolved, largely due to standardisation of practice, measurement of outcomes and the introduction of the Best Practice Tariff, leading to the sustained improvements documented by the National Hip Fracture Database (NHFD). The treatment of distal femoral fractures in this population has not had the same emphasis. This study defines the epidemiology, current practice and outcomes of distal femoral fractures in four English centres. Patients and methods 105 patients aged 50 years or greater with a distal femoral fracture, presenting to four UK major trauma centres between October 2010 and September 2011 were identified. Data was collected using an adapted NHFD data collection tool via retrospective case note and radiograph review. Local ethics approval was obtained. Results Mean age was 77 years (range 50–99), with 86% female. 95% of injuries were sustained from a low energy mechanism, and 72% were classified as either 33-A1 or 33-C1. The mean Parker mobility score and Barthel Independence Index were 5.37 (0–9) and 75.5 (0–100) respectively. Operative management was performed in 84%, and 86% had their surgery within 36 h. Three quarters were fixed with a peri-articuar locking plate. There was no consensus on post operative rehabilitation, but no excess of complications in the centres where weight bearing as tolerated was the standard. 45% were seen by an orthogeriatrician during their admission. Mean length of stay was 29 days. Mortality at 30 days, 6 months, and 1 year was 7%, 16% and 18% respectively. Discussion This study demonstrates that the distal femoral and hip fracture populations are similar, and highlights the current disparity in their management. The metrics and standards of care currently applied to hip fractures should be applied to the treatment of distal femoral fractures. Optimal operative treatment and rehabilitation remains unclear, and is in need of further research.
TL;DR: Following this study and literature data, antibiotic-coated implants seem a potential option for prevention of deep infection in trauma patients, although this statement needs to be confirmed by large randomised clinical trials.
Abstract: Introduction Despite modern advances in fracture care, deep (implant-related) infection remains a problem in the treatment of tibia fractures. There is some evidence that antibiotic-coated implants are beneficial in the prevention of this sometimes devastating complication. In the following study we describe our results using a gentamicin-coated intramedullary tibia nail (Expert Tibia Nail (ETN) PROtect™) for the surgical treatment of complex open tibia fracture and revision cases. Materials and methods We describe the outcome of patients treated between January 2012 and September 2013, using a gentamicin-coated intramedullary tibia nail. Treatment indications included acute, Gustilo grade II–III, open tibia fractures or closed tibia fractures with long-term external fixation prior to intramedullary nailing and complex tibia fracture revision cases with a mean of three prior surgical interventions. Outcome parameters in this study were deep infection and nonunion. Results In total, 16 consecutive patients with 16 tibia fractures were treated with a gentamicin-coated intramedullary nail. The overall patient population was subdivided into two groups. The first group consisted of 11 patients (68.8%) with acute fractures who were treated with a gentamicin-coated intramedullary nail. The second group consisted of 5 complex revision cases (31.2%). In our patient population no deep infections could be noted after the treatment with a gentamicin-coated tibia nail. Nonunion was diagnosed in 4 patients (25.0%), 1 of these was a revision case. Conclusions Musculoskeletal complications place a cost burden on total healthcare expenditure. Better understanding of the epidemiology and pathogenesis is essential because this can lead to prevention rather than treatment strategies. The purpose of the study was to evaluate a gentamicin-coated tibia nail in the prevention of deep (implant-related) infection. In our patient population no deep infections occurred after placement of the gentamicin-coated nail. Following this study and literature data, antibiotic-coated implants seem a potential option for prevention of deep infection in trauma patients. In the future this statement needs to be confirmed by large randomised clinical trials.
TL;DR: Although this study shows good radiological results following methods of treatment in accordance with the Vancouver classification, there was marked functional deterioration in many patients and a high rate of complications.
Abstract: Background The aim of this study was to determine the functional and radiological results of the treatment of periprosthetic femoral fractures. Materials and methods A review was performed of all periprosthetic femur fractures after a total hip arthroplasty (THA) or hemiarthroplasty (HA) treated at our institution from 1995 to 2011. Functional outcome was assessed in terms of the Harris Hip Score and ambulatory status. Radiological findings were classified using Beals and Tower's criteria. Results A total of 59 periprosthetic fractures were identified in 58 patients. The mean age of patients was 79 years old and the mean follow-up time was 33.6 months. Local risk factors were identified in 71% of the patients, principally osteoporosis (59%), followed by osteolysis (24%) and loosening of the stem (19%). In the multivariable analysis, the presence of local risk factors was associated with worsening of patients’ ambulatory status. According to the Vancouver classification, there were 8 type A, 46 type B and 5 type C fractures. Of the type B fractures 24 were B1, 14 were B2 and 8 were B3. Fracture union was achieved in 54 fractures, with a mean union time of 6 months. Applying Beals and Tower's criteria, radiological results were excellent in 20 patients (34%), good in 22 (37%), and poor in 17 (29%). None of the patients improved their ability to walk after these fractures and 31 patients (52%) did not regain their prefracture walking status. The mean Harris Hip Score postoperatively was 67.9. There were major or minor complications in 33 patients (56%) and 11 patients (19%) required further operations. Conclusion Although this study shows good radiological results following methods of treatment in accordance with the Vancouver classification, there was marked functional deterioration in many patients and a high rate of complications. Local risk factors were associated with poorer ambulatory status.
TL;DR: In the search for a simple and inexpensive, easy to calculate, objective and accurate tool, the NHFS may be the most appropriate of the currently available scores for hip fracture patients, however more studies need to be undertaken before it becomes a national hip fracture risk stratification or audit tool of choice.
Abstract: Rationale Accurate peri-operative risk prediction is an essential element of clinical practice. Various risk stratification tools for assessing patients’ risk of mortality or morbidity have been developed and applied in clinical practice over the years. This review aims to outline essential characteristics (predictive accuracy, objectivity, clinical utility) of currently available risk scoring tools for hip fracture patients. Methods We searched eight databases; AMED, CINHAL, Clinical Trials.gov, Cochrane, DARE, EMBASE, MEDLINE and Web of Science for all relevant studies published until April 2015. We included published English language observational studies that considered the predictive accuracy of risk stratification tools for patients with fragility hip fracture. Results After removal of duplicates, 15,620 studies were screened. Twenty-nine papers met the inclusion criteria, evaluating 25 risk stratification tools. Risk stratification tools considered in more than two studies were; ASA, CCI, E-PASS, NHFS and O-POSSUM. All tools were moderately accurate and validated in multiple studies; however there are some limitations to consider. The E-PASS and O-POSSUM are comprehensive but complex, and require intraoperative data making them a challenge for use on patient bedside. The ASA, CCI and NHFS are simple, easy and inexpensive using routinely available preoperative data. Contrary to the ASA and CCI which has subjective variables in addition to other limitations, the NHFS variables are all objective. Conclusion In the search for a simple and inexpensive, easy to calculate, objective and accurate tool, the NHFS may be the most appropriate of the currently available scores for hip fracture patients. However more studies need to be undertaken before it becomes a national hip fracture risk stratification or audit tool of choice.
TL;DR: Based on the experience presented in this paper, it is believed that emphasis should be placed on timely transfer to a specialist centre, aiming for a single-stage combined orthoplastic procedure to achieve definitive fixation and soft tissue coverage and optimal outcomes.
Abstract: Background Grade III open fractures of the tibia represent a serious injury It is recognised that combined management of these cases by experienced orthopaedic and plastic surgeons improves outcomes Previous studies have not considered the timing of definitive soft tissue cover in relation to the definitive orthopaedic management This paper reviews the outcomes in patients treated in an orthoplastic unit where the emphasis was on undertaking the definitive orthopaedic and plastic surgical procedures in a single stage, following initial debridement and temporary stabilisation as necessary Methods We reviewed medical notes of 73 consecutive patients with 74 Grade III open tibia fractures (minimum 1 year follow up), to compare deep infection rates in patients who had (a) a single-stage definitive fixation and soft tissue coverage vs those who had separate operations, and (b) those who had definitive treatment completed in 72 h Results (a) Combined Single-stage Orthoplastic Fixation and Coverage: 48 fractures were managed with definitive orthopaedic fixation and plastic surgical coverage performed at the same time, whilst 26 had these performed at separate stages Of those subjects that had definitive fixation and coverage in one procedure 2 (42%) developed deep infections, compared with 9 (346%) deep infections (p Conclusion Joint orthoplastic operating lists facilitate simultaneous definitive fixation and cover that greatly reduces infection rates Based on our experience presented in this paper, we believe that emphasis should be placed on timely transfer to a specialist centre, aiming for a single-stage combined orthoplastic procedure to achieve definitive fixation and soft tissue coverage and optimal outcomes
TL;DR: This study failed to prove any essential association between timing of NOF fracture internal fixation and incidence of AVN, but indicated that delay of internal fixation of more than 24h could increase substantially the odds of non-union.
Abstract: The aim of the present study was to evaluate the effect of timing of internal fixation of intracapsular fractures of the neck of femur on the development of late complications, particularly osteonecrosis of femoral head (ONFH) and non-union. We undertook a systematic review of the literature adhering to the PRISMA guidelines. There were 7 eligible reports for the final analysis. The methodological quality of component studies was assessed with the Coleman Methodology Score (CMS). Each included study was assigned a score independently by the two reviewers. The final score of each individual study constituted the average value of the scores given by the two reviewers. The agreement between the two assessors was tested with intraclass correlation coefficient (ICC). The CMS ranged from 37 to 64 within component studies (mean: 46.5, SD: 10.8, median: 41). The ICC was 0.94 (95% CI: 0.69-0.99), implying a nearly perfect agreement between the two assessors. Based on the available data regarding the timing of operative fixation of the femoral neck fractures, 4 discreet pairs of comparison groups could be created: (1) fractures fixed within 6h from injury versus fractures fixed after 6h from injury; (2) fractures fixed within 12h versus after 12h; (3) fractures fixed within 24h versus after 24h; and (4) fractures fixed within 6h versus after 24h. Outcome measures were analyzed within each one of the above pairs of treatment groups. The following subgroups analyses were a priori decided: (1) initial fracture displacement (displaced vs. undisplaced fractures); (2) fixation method (cannulated screws vs. sliding hip screw); (3) quality of reduction (anatomic vs non-anatomic reduction). This study failed to prove any essential association between timing of NOF fracture internal fixation and incidence of AVN. With respect to non-union though, it indicated that delay of internal fixation of more than 24h could increase substantially the odds of non-union.
TL;DR: This is the first study to describe mid- to long-term functional outcome after ORIF for all types of tibial plateau fractures, with the use of the KOOS, and shows that radiological characteristics of osteoarthritis are not related with lower functional outcomes in the mid-to-long-term.
Abstract: Background Tibial plateau fractures account for approximately 1% of all fractures. They usually occur after a direct high-energy trauma. Despite adequate treatment, these fractures can result in malalignment and secondary osteoarthritis (OA). Research concerning long-term functional outcome is limited. The primary aim of this study was to evaluate mid- to long-term functional outcome of surgically treated tibial plateau fractures. The secondary aim was to investigate whether radiological characteristics of OA one year after surgery are predictive of functional outcome at follow-up. Methods All consecutive patients with fractures of the proximal tibia, which were surgically treated in our level-2 trauma centre between 2004 and 2010, were included in this study. Initial trauma radiographs were analysed for fracture classification, using both the Schatzker and AO/OTA classification systems, by three different raters. Immediate postoperative and 1-year postoperative radiographs were analysed for osteoarthritis by an experienced radiologist, using the Kellgren and Lawrence scale. Functional outcome of the included patients was measured using the Dutch version of the Knee injury and Osteoarthritis Outcome Score (KOOS) questionnaire. Results Seventy one patients out of a group of 96 included patients completed the survey. Median KOOS scores are 89.8% for pain, 91.1% for ‘other symptoms’, 89.7% for daily function, 72.5% for sports and recreation and 75.0% for quality of life. Median KOOS overall score is 82.99%. We did not find a correlation between the KOOS scores and the absolute age for any of the subscales. There was no significant relationship between radiological characteristics of osteoarthritis and functional outcome. Conclusions This is the first study to describe mid- to long-term functional outcome after ORIF for all types of tibial plateau fractures, with the use of the KOOS. Patients should be informed about the likelihood of lower functional outcome in the long-term. This study shows that radiological characteristics of osteoarthritis are not related with lower functional outcomes in the mid- to long-term.
TL;DR: The RRCB proved to be feasible and accepted, feasible, acceptable and potentially efficacious in patients with acute musculoskeletal trauma and its preliminary effect in reducing disability and pain intensity as compared to standard care.
Abstract: Objective To test the acceptability and feasibility of a mind body skills-based intervention (RRCB) and estimate its preliminary effect in reducing disability and pain intensity as compared to standard care (SC) in patients with acute musculoskeletal trauma. Design Randomised controlled trial. Setting Level I trauma centre. Patients Adult patients with acute fractures at risk for chronic pain and disability based on scores on two coping with pain measures who presented to an orthopedic trauma center and met inclusion and exclusion criteria. Intervention Participants were randomied to either RRCB with SC or SC alone. Main outcome measurement Disability (short musculoskeletal functional assessment, SMFA) and pain (Numerical Analogue Scale). Secondary outcome measures: coping strategies (Pain Catastrophizing Scale, PCS and Pain Anxiety Scale, PAS) and mood (CESD Depression and PTSD checklist). Results Among the 50 patients consented, two did not complete the initial assessment. Of these, the first four received the intervention as part of an open pilot and the next 44 were randomised (24 RRCBT and 20 UC) and completed initial assessment. We combined the patients who received RRCB into one group, N = 28. Of the entire sample, 34 completed time two assessments (24 RRCBT and 10 SC). The RRCB proved to be feasible and accepted (86% retention, 28 out of 24 completers). Analyses of covariance ANCOVA showed a significant (p Conclusion The RRCB is feasible, acceptable and potentially efficacious. Level of evidence Level 1 prognostic.
TL;DR: Patients who underwent hip fracture surgery with general anaesthesia had a higher risk of thirty-day complications as compared to patients who underwent Hip fracture repair with spinal anaesthesia, and surgeons should consider using spinal anaesthetic for hip fractures.
Abstract: Background Spinal anaesthesia when compared to general anaesthesia has been shown to decrease postoperative morbidity in orthopaedic surgery. The aim of the present study was to assess the differences in thirty-day morbidity and mortality for patients undergoing hip fracture surgery with spinal versus general anaesthesia. Methods The American College of Surgeons National Surgical Quality and Improvement Program (NSQIP) database was used to identify patients who underwent hip fracture surgery with general or spinal anaesthesia between 2010 and 2012 using CPT codes 27245 and 27244. Patient characteristics, complications, and mortality rates were compared. Univariate analysis and multivariate logistic regression were used to identify predictors of thirty-day complications. Stratified propensity scores were employed to adjust for potential selection bias between cohorts. Results 6133 patients underwent hip fracture surgery with spinal or general anaesthesia; 4318 (72.6%) patients underwent fracture repair with general anaesthesia and 1815 (27.4%) underwent fracture repair with spinal anaesthesia. The spinal anaesthesia group had a lower unadjusted frequency of blood transfusions (39.34% versus 45.49%; p p =0.004), urinary tract infection (8.87% versus 5.76%; p p =0.001). The length of surgery was shorter in the spinal anaesthesia group (55.81 versus 65.36min; p p =0.0002) was significantly associated with increased risk for complication after hip fracture surgery. Age, female sex, body mass index, hypertension, transfusion, emergency procedure, operation time, and ASA score were risk factors for complications after hip fracture repair (all p Conclusions Patients who underwent hip fracture surgery with general anaesthesia had a higher risk of thirty-day complications as compared to patients who underwent hip fracture repair with spinal anaesthesia. Surgeons should consider using spinal anaesthesia for hip fracture surgery.
TL;DR: It is hypothesized that low-intensity pulsed ultrasound (LIPUS) can enhance heal rate (HR) in fractures that remain nonunion after one year, relative to the expected HR in the absence of treatment, which is expected to be negligible.
Abstract: Background Established fracture nonunions rarely heal without secondary intervention. Revision surgery is the most common intervention, though non-surgical options for nonunion would be useful if they could overcome nonunion risk factors. Our hypothesis is that low-intensity pulsed ultrasound (LIPUS) can enhance heal rate (HR) in fractures that remain nonunion after one year, relative to the expected HR in the absence of treatment, which is expected to be negligible. Methods We collated outcomes from a prospective patient registry required by the U.S. Food & Drug Administration. Patient data were collected over a 4-year period beginning in 1994 and were individually reviewed and validated by a registered nurse. Patients were only included if they had four data points available: date when fracture occurred; date when LIPUS treatment began; date when LIPUS treatment ended; and a dichotomous outcome of healed vs. failed, assessed by clinical and radiological criteria. Data were used to calculate two derived variables: days to treatment (DTT) with LIPUS, and days on treatment (DOT) with LIPUS. Every validated chronic nonunion patient (DTT > 365 days) with complete data is reported. Results Heal rate for chronic nonunion patients (N = 767) treated with LIPUS was 86.2%. Heal rate was 82.7% among 98 patients with chronic nonunion ≥5 years duration, and 12 patients healed after chronic nonunion >10 years (HR = 63.2%). There was more patient loss to follow-up, non-compliance, and withdrawal, comparing chronic nonunion patients to all other patients (p Conclusions Low-intensity pulsed ultrasound enhanced HR among fractures that had been nonunion for at least 1 year, and even healed fractures that had been nonunion >10 years. LIPUS resulted in successful healing in the majority of nonunions without further surgical intervention.

TL;DR: Data from this large multicenter trial demonstrates that predicting the need for MT continues to be a challenge, and a more reliable algorithm is needed to identify and treat these severely injured patients earlier.
Abstract: Introduction Early recognition and treatment of trauma patients requiring massive transfusion (MT) has been shown to reduce mortality. While many risk factors predicting MT have been demonstrated, there is no universally accepted method or algorithm to identify these patients. We hypothesised that even among experienced trauma surgeons, the clinical gestalt of identifying patients who will require MT is unreliable. Methods Transfusion and mortality outcomes after trauma were observed at 10 U.S. Level-1 trauma centres in patients who survived ≥30 min after admission and received ≥1 unit of RBC within 6 h of arrival. Subjects who received ≥10 units within 24 h of admission were classified as MT patients. Trauma surgeons were asked the clinical gestalt question “Is the patient likely to be massively transfused?” 10 min after the patients arrival. The performance of clinical gestalt to predict MT was assessed using chi-square tests and ROC analysis to compare gestalt to previously described scoring systems. Results Of the 1245 patients enrolled, 966 met inclusion criteria and 221 (23%) patients received MT. 415 (43%) were predicted to have a MT and 551(57%) were predicted to not have MT. Patients predicted to have MT were younger, more often sustained penetrating trauma, had higher ISS scores, higher heart rates, and lower systolic blood pressures (all p Conclusion Data from this large multicenter trial demonstrates that predicting the need for MT continues to be a challenge. Because of the increased mortality associated with delayed therapy, a more reliable algorithm is needed to identify and treat these severely injured patients earlier.
TL;DR: MRI was observed to have a higher diagnostic accuracy than CT in detecting occult fractures of the hip and interobserver analysis showed high kappa values corresponding substantial agreement in both CT and MRI.
Abstract: Objective To estimate sensitivity and specificity of CT and MRI examinations in patients with fractures of the proximal femur. To determine the interobserver agreement of the modalities among a senior consulting radiologist, a resident in radiology and a resident in orthopaedics surgery. Materials and methods 67 patients (27 males, 40 females, mean age 80.5) seen in the emergency room with hip pain after fall, inability to stand and a primary X-ray without fracture were evaluated with both CT and MRI. The images were analysed by a senior consulting musculoskeletal radiologist, a resident in radiology and a resident in orthopaedic surgery. Sensitivity and specificity were estimated with MRI as the golden standard. Kappa value was used to assess level of agreement in both MRI and CT finding. Results 15 fractures of the proximal femur were found (7 intertrochanteric-, 3 femoral neck and 5 fractures of the greater trochanter). Two fractures were not identified by CT and four changed fracture location. Among those, three patients underwent surgery. Sensitivity of CT was 0.87; 95% CI [0.60; 0.98]. Kappa for interobserver agreement for CT were 0.46; 95% CI [0.23; 0.76] and 0.67; 95% CI [0.42; 0.90]. For MRI 0.67; 95% CI [0.43; 0.91] and 0.69; 95% CI [0.45; 0.92]. Conclusion MRI was observed to have a higher diagnostic accuracy than CT in detecting occult fractures of the hip. Interobserver analysis showed high kappa values corresponding substantial agreement in both CT and MRI.
TL;DR: Investigation of the major and minor adverse events and risk factors for complication development associated with five common surgeries for the treatment of hip fractures using the NSQIP database found hip fractures are associated with significantly high numbers of adverse events.
Abstract: Introduction Hip fractures are one of the most common types of orthopaedic injury with high rates of morbidity. Currently, no study has compared risk factors and adverse events following the different types of hip fracture surgeries. The purpose of this paper is to investigate the major and minor adverse events and risk factors for complication development associated with five common surgeries for the treatment of hip fractures using the NSQIP database. Methods Using the ACS-NSQIP database, complications for five forms of hip surgeries were selected and categorized into major and minor adverse events. Demographics and clinical variables were collected and an unadjusted bivariate logistic regression analyses was performed to determine significant risk factors for adverse events. Five multivariate regressions were run for each surgery as well as a combined regression analysis. Results A total of 9640 patients undergoing surgery for hip fracture were identified with an adverse events rate of 25.2% ( n = 2433). Open reduction and internal fixation of a femoral neck fracture had the greatest percentage of all major events (16.6%) and total adverse events (27.4%), whereas partial hip hemiarthroplasty had the greatest percentage of all minor events (11.6%). Mortality was the most common major adverse event (44.9–50.6%). For minor complications, urinary tract infections were the most common minor adverse event (52.7–62.6%). Significant risk factors for development of any adverse event included age, BMI, gender, race, active smoking status, history of COPD, history of CHF, ASA score, dyspnoea, and functional status, with various combinations of these factors significantly affecting complication development for the individual surgeries. Conclusions Hip fractures are associated with significantly high numbers of adverse events. The type of surgery affects the type of complications developed and also has an effect on what risk factors significantly predict the development of a complication. Concerted efforts from orthopaedists should be made to identify higher risk patients and prevent the most common adverse events that occur postoperatively.
