Fracture fixation in the operative management of hip fractures (FAITH): an international, multicentre, randomised controlled trial

Abstract: textBackground Reoperation rates are high after surgery for hip fractures We investigated the effect of a sliding hip screw versus cancellous screws on the risk of reoperation and other key outcomes Methods For this international, multicentre, allocation concealed randomised controlled trial, we enrolled patients aged 50 years or older with a low-energy hip fracture requiring fracture fixation from 81 clinical centres in eight countries Patients were assigned by minimisation with a centralised computer system to receive a single large-diameter screw with a side-plate (sliding hip screw) or the present standard of care, multiple small-diameter cancellous screws Surgeons and patients were not blinded but the data analyst, while doing the analyses, remained blinded to treatment groups The primary outcome was hip reoperation within 24 months after initial surgery to promote fracture healing, relieve pain, treat infection, or improve function Analyses followed the intention-to-treat principle This study was registered with ClinicalTrialsgov, number NCT00761813 Findings Between March 3, 2008, and March 31, 2014, we randomly assigned 1108 patients to receive a sliding hip screw (n=557) or cancellous screws (n=551) Reoperations within 24 months did not differ by type of surgical fixation in those included in the primary analysis: 107 (20%) of 542 patients in the sliding hip screw group versus 117 (22%) of 537 patients in the cancellous screws group (hazard ratio [HR] 0·83, 95% CI 0·63–1·09; p=0·18) Avascular necrosis was more common in the sliding hip screw group than in the cancellous screws group (50 patients [9%] vs 28 patients [5%]; HR 1·91, 1·06–3·44; p=0·0319) However, no significant difference was found between the number of medically related adverse events between groups (p=0·82; appendix); these events included pulmonary embolism (two patients [<1%] vs four [1%] patients; p=0·41) and sepsis (seven [1%] vs six [1%]; p=0·79) Interpretation In terms of reoperation rates the sliding hip screw shows no advantage, but some groups of patients (smokers and those with displaced or base of neck fractures) might do better with a sliding hip screw than with cancellous screws Funding National Institutes of Health, Canadian Institutes of Health Research, Stichting NutsOhra, Netherlands Organisation for Health Research and Development, Physicians' Services Incorporated

Low intensity pulsed ultrasound (LIPUS) for bone healing: A clinical practice guideline

Abstract: Does low intensity pulsed ultrasound (LIPUS) accelerate recovery in adults and children who have experienced bone fractures or osteotomy (cutting of a bone)? An expert panel rapidly produced these recommendations based on a linked systematic review triggered by a large multi-centre randomised trial in adults with tibial fracture.

High Irritation and Removal Rates After Plate or Nail Fixation in Patients With Displaced Midshaft Clavicle Fractures

Abstract: Background: Studies comparing plate with intramedullary nail fixation of displaced midshaft clavicle fractures show faster recovery in the plate group and implant-related complications in both groups after short-term followup (6 or 12 months). Knowledge of disability, complications, and removal rates beyond the first postoperative year will help surgeons in making a decision regarding optimal implant choice. However, comparative studies with followup beyond the first year or two are scarce. Questions/purposes: We asked: (1) Does plate fixation or intramedullary nail fixation for displaced midshaft clavicle fractures result in less disability? (2) Which type of fixation, plate or intramedullary, is more frequently associated with implant-related irritation and implant removal? (3) Is plate or intramedullary fixation associated with postoperative complications beyond the first postoperative year? Methods: Between January 2011 and August 2012, patients with displaced midshaft clavicle fractures were enrolled and randomized to plate or intramedullary nail fixation. A total of 58 patients with plate and 62 patients with intramedullary nails initially were enrolled. Minimum followup was 30 months (mean, 39 months; range, 30–51 months). Two patients (3%) with plate fixation and two patients (3%) with intramedullary nails were lost to followup. The Quic

Out of hospital thoracotomy for cardiac arrest after penetrating thoracic trauma

Abstract: Introduction: Emergency department thoracotomy is an established procedure for cardiac arrest in patients suffering from penetrating thoracic trauma and yields relatively high survival rates (up to 21%) in patients with cardiac tamponade. To minimize the delay between arrest and thoracotomy, some have advocated thoracotomy on the accident scene. The aim of this study was to determine the proportion of patients with return of spontaneous circulation and subsequent survival after out of hospital thoracotomy in the Netherlands. Methods: A retrospective analysis of data collected on all out of

Muscle wasting and survival following pre-operative chemoradiotherapy for locally advanced rectal carcinoma

Abstract: Background & aims: Neoadjuvant chemoradiotherapy (NACRT) has increased local control in locally advanced rectal cancer. Reduced skeletal muscle mass (sarcopenia), or ongoing muscle wasting, is associated with decreased survival in cancer. This study aims to assess the change in body composition during NACRT and its impact on outcome using computed tomography (CT) imaging in locally advancedrectal cancer (LARC) patients. Methods: LARC patients treated with NACRT were selected from a prospectively maintained database and retrospectively analyzed. One-hundred twenty-two patients who received treatment between 2004 and 2012 with available diagnostic CT imaging obtained before and after NACRT were identified. Cross-sectional areas for skeletal muscle was determined, and subsequently normalized for patient height. Differences between skeletal muscle areas before and after NACRT were computed, and their influenceon overall and disease-free survival was assessed. Results: A wide distribution in change of body composition was observed. Loss of skeletal muscle mass during chemoradiotherapy was independently associated with disease-free survival (HR0.971; 95% CI:0.946e0.996; p¼0.025) and distant metastasis-free survival (HR0.942; 95% CI: 0.898e0.988; p¼0.013).No relation was observed with overall survival in the current cohort. Conclusions:Loss of skeletal muscle mass during NACRT in rectal cancer patients is an independent prognostic factor for disease-free survival and distant metastasis-free survival following curative intentresection.

Increase in intracranial pressure by application of a rigid cervical collar: a pilot study in healthy volunteers

Abstract: OBJECTIVES Rigid cervical collars are known to increase intracranial pressure (ICP) in severe traumatic brain injury (TBI). Cerebral blood flow might decrease according to the Kellie Monroe doctrine. For this reason, the use of the collar in patients with severe TBI has been abandoned from several trauma protocols in the Netherlands. There is no evidence on the effect of a rigid collar on ICP in patients with mild or moderate TBI or indeed patients with no TBI. As a first step we tested the effect in healthy volunteers with normal ICPs and intact autoregulation of the brain. METHODS In this prospective blinded cross-over study, we evaluated the effect of application of a rigid cervical collar in 45 healthy volunteers by measuring their optical nerve sheath diameter (ONSD) by transocular sonography. Sonographic measurement of the ONSD behind the eye is an indirect noninvasive method to estimate ICP and pressure changes. RESULTS We included 22 male and 23 female volunteers. In total 360 ONSD measurements were performed in these 45 volunteers. Application of a collar resulted in a significant increase in ONSD in both the left (β=0.06, 95% confidence interval: 0.05-0.07, P<0.001) and the right eye (β=0.01, 95% confidence interval: 0.00-0.02, P=0.027) CONCLUSION: Application of a rigid cervical collar significantly increases the ONSD in healthy volunteers with intact cerebral autoregulation. This suggests that ICP may increase after application of a collar. In healthy volunteers, this seems to be of minor importance. On the basis of our findings the effect of a collar on ONSD and ICP in patients with mild and moderate TBI needs to be determined.

Risk factors for infectious complications after open fractures; a systematic review and meta-analysis

Abstract: __Purpose__ The purpose of this study was to identify risk factors for the development of infection after open fracture fixation. __Methods__ A comprehensive search in all scientific literature of the last 30 years was performed in order to identify patient-, trauma-, diagnosis- and treatment-related risk fa

The relationship between physical and psychological complaints and quality of life in severely injured patients

Abstract: Purpose: The purpose of this study was two-fold. The first goal was to investigate which variables were associated with the remaining physical limitations of severely injured patients after the initial rehabilitation phase. Second, we investigated whether physical limitations were attributable to the association between psychological complaints and quality of life in this patient group. Methods: Patients who were 18 years or older and who had an injury severity score (ISS). >. 15 completed a set of questionnaires at one time-point after their rehabilitation phase (15-53 months after their trauma). The Short Musculoskeletal Function Assessment (SMFA) questionnaire was used to determine physical limitations. The Hospital Anxiety and Depression Scale, the Dutch Impact of Event Scale and the Cognitive Failure Questionnaire were used to determine psychological complaints, and the World Health Organization Quality of Life assessment instrument-BREF was used to measure general Quality of Life (QOL).Differences in physical limitations were investigated for several trauma- and patient-related variables using non-parametric independent-sample Mann-Whitney U tests. Multiple linear regression was performed to investigate whether the decreased QOL of severely injured patients with psychological complaints could be explained by their physical limitations. Results: Older patients, patients with physical complaints before the injury, patients with higher ISS scores, and patients who had an injury of the spine or of the lower extremities reported significantly more physical problems. Additionally, patients with a low education level, patients who were living alone, and those who were unemployed reported significantly more long-term physical problems.Severely injured patients without psychological complaints reported significantly less physical limitations than those with psychological complaints. The SMFA factor of Lower extremity dysfunction

Recognition and management of intra-abdominal hypertension and abdominal compartment syndrome; a survey among Dutch surgeons

Abstract: Purpose: Intra-abdominal hypertension (IAH) and Abdominal compartment syndrome (ACS) are relatively rare, but severe complications. Although many advances were made in recent years, the recognition and management remain subject of debate. The aim of this study was to determine the current state of awareness, knowledge and use of evidence-based medicine regarding IAH and ACS among Dutch surgeons. Methods: A literature-based and expert consensus survey was developed. One surgeon in every hospital in The Netherlands was asked to complete the online questionnaire. Results: Sixty of 87 (69 %) invited surgeons completed the questionnaire. Intra-abdominal pressure (IAP) was measured using intra-vesical methods by 55 (98 %) respondents. Diuretics (N = 38; 63 %) and laparotomy (N = 33; 55 %) were considered useful treatments for IAH or prevention of ACS by a majority. Only 16 (27 %) respondents used these guidelines in daily practice, and 37 (62 %) respondents are willing to do so. Although 35 (58 %) surgeons agreed that IAH is only a symptom, not requiring treatment. Forty-one percent of experienced respondents suggested that prevalence of ACS remained unchanged. Nearly all respondents (N = 59; 98 %) believed that open abdomen management improves patient outcomes, many (N = 46; 77 %) confirm the high complications rate of this treatment. Conclusion: The definitions of IAH and ACS and the related diagnostic and therapeutic challenges are relatively well known by Dutch surgeons. Despite limited use of the evidence-based guid

Early mobilisation versus plaster immobilisation of simple elbow dislocations: Results of the FuncSiE multicentre randomised clinical trial

Abstract: Background/aim To compare outcome of early mobilisation and plaster immobilisation in patients with a simple elbow dislocation. We hypothesised that early mobilisation would result in earlier functional recovery. Methods From August 2009 to September 2012, 100 adult patients with a simple elbow dislocation were enrolled in this multicentre randomised controlled trial. Patients were randomised to early mobilisation (n=48) or 3 weeks plaster immobilisation (n=52). Primary outcome measure was the Quick Disabilities of the Arm, Shoulder, and Hand (Quick-DASH) score. Secondary outcomes were the Oxford Elbow Score, Mayo Elbow Performance Index, pain, range of motion, complications and activity resumption. Patients were followed for 1 year. Results Quick-DASH scores at 1 year were 4.0 (95% CI 0.9 to 7.1) points in the early mobilisation group versus 4.2 (95% CI 1.2 to 7.2) in the plaster immobilisation group. At 6 weeks, early mobilised patients reported less disability (Quick-DASH 12 (95% CI 9 to 15) points vs 19 (95% CI 16 to 22); p<0.05) and had a larger arc of flexion and extension (121° (95% CI 115° to 127°) vs 102° (95% CI 96° to 108°); p<0.05). Patients returned to work sooner after early mobilisation (10 vs 18 days; p=0.020). Complications occurred in 12 patients; this was unrelated to treatment. No recurrent dislocations occurred. Conclusions Early active mobilisation is a safe and effective treatment for simple elbow dislocations. Patients recovered faster and returned to work earlier without increasing the complication rate. No evidence was found supporting treatment benefit at 1 year.

The American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale; Translation and validation of the Dutch language version for ankle fractures

Abstract: Objectives The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale is among the most commonly used instruments for measuring outcome of treatment in patients who sustained a complex ankle or hindfoot injury. It consists of a patient-reported and a physician-reported part. A validated, Dutch version of this instrument is currently not available. The aim of this study was to translate the instrument into Dutch and to determine the measurement properties of the AOFAS Ankle-Hindfoot Scale Dutch language version (DLV) in patients with a unilateral ankle fracture. Setting Multicentre (two Dutch hospitals), prospective observational study. Participants In total, 142 patients with a unilateral ankle fracture were included. Ten patients were lost to follow-up. Primary and secondary outcome measures Patients completed the subjective (patient-reported) part of the AOFAS Ankle-Hindfoot Scale-DLV. A physician or trained physician-assistant completed the physician-reported part. For comparison and evaluation of the measuring characteristics, the Foot Function Index and the Short Form-36 were completed by the patient. Descriptive statistics (including floor and ceiling effects), reliability (ie, internal consistency), construct validity, reproducibility (ie, test-retest reliability, agreement and smallest detectable change) and responsiveness were determined. Results The AOFAS-DLV and its subscales showed good internal consistency (Cronbach's α >0.90). Construct validity and longitudinal validity were proven to be adequate (76.5% of predefined hypotheses were confirmed). Floor effects were not present. Ceiling effects were present from 6 months onwards, as expected. Responsiveness was adequate, with a smallest detectable change of 12.0 points. Conclusions The AOFAS-DLV is a reliable, valid and responsive measurement instrument for evaluating functional outcome in patients with a unilateral ankle fracture. This implies that the questionnaire is suitable to compare different treatment modalities within this population or to compare outcome across hospitals.

Soft tissue complications and timing of surgery in patients with a tongue-type displaced intra-articular calcaneal fracture : An international retrospective cohort study

Abstract: Introduction: Tongue-type displaced intra-articular calcaneal fractures (DIACF) are associated with a specific pattern of fracture displacement in contrast to joint depression fractures. This may result in tension of soft tissue in the posterior part of the heel. Tension-induced ischemia can result in skin necrosis. The objectives of this study were to investigate whether patients with tongue-type calcaneal fractures exert a higher risk of complications, especially of the posterior soft tissues, than joint depression type fractures. Also, late interventions (e.g., antibiotics, debridements, and amputations) and the effect of timing of surgery on the complication rate was assessed. Methods: In this international retrospective cohort study, data of adult patients with a DIACF in the period January 1, 2005-December 31, 2015 were extracted from patients' medical files. Descriptive, univariate, and multivariable analyses were performed in SPSS. Results: A total of 560 patients with 632 DIACF were included (295 tongue-type and 337 non-tongue-type fractures). At hospital presentation, 20.3% of the patients with a tongue-type fracture had compromised posterior soft tissue versus 12.8% with non-tongue-type fractures (p = 0.032). However, corrected for potential confounders the risk was no longer statistically significant (OR 1.497; 95% CI 0.831-2.696). Patients with a TT-DIACF had a 1.2-3.4-fold higher rate of any local wound complication (deep infections, and full thickness lesions, p < 0.03). In addition they had 2.0-8.0-fold more intravenous antibiotics, debridements, soft tissue coverage procedures and amputations (p < 0.03). Patients who underwent surgery within two days after trauma had a higher risk to develop any complication, in particular superficial infections, when compared to surgery between 3-7 days, but no significant difference between 3 and 7 and ≥8 days could be demonstrated. Conclusion: Despite the fact that patients with a tongue-type fracture developed posterior skin and soft tissue compromise nearly twice as often, this difference disappeared after correction for confounders. The overall complication risk was increased in patients with tongue-type calcaneal fractures as compared to patients with a non-tongue-type fracture. Whether or not patients with tongue-type fractures require immediate surgery cannot be concluded from the data.

Reliability, validity, responsiveness, and minimal important change of the Disabilities of the Arm, Shoulder and Hand and Constant-Murley scores in patients with a humeral shaft fracture

Abstract: Background: The Disabilities of the Arm, Shoulder and Hand (DASH) and Constant-Murley scores are commonly used instruments. The DASH is patient-reported, and the Constant-Murley combines a clinician-reported and a patient-reported part. For patients with a humeral shaft fracture, their validity, reliability, responsiveness, and minimal important change (MIC) have not been published. This study evaluated the measurement properties of these instruments in patients who sustained a humeral shaft fracture. Methods: The DASH and Constant-Murley instruments were completed 5 times until 1 year after trauma. Pain score, Short Form 36, and EuroQol-5D were completed for comparison. Internal consistency was determined by the Cronbach α. Construct and longitudinal validity were evaluated by assessing hypotheses about expected Spearman rank correlations in scores and change scores, respectively, between patient-reported outcome measures (sub)scales. The smallest detectable change (SDC) was calculated. The MIC was determined using an anchor-based approach. The presence of floor and ceiling effects was determined. Results: A total of 140 patients were included. Internal consistency was sufficient for DASH (Cronbach α = 0.96) but was insufficient for Constant-Murley (α = 0.61). Construct and longitudinal validity were sufficient for both patient-reported outcome measures (>75% of correlations hypothesized correctly). The MIC and SDC were 6.7 (95% confidence inte

The validity and accuracy of MRI arthrogram in the assessment of painful articular disorders of the hip

Abstract: textThe assessment of a patient with chronic hip pain can be challenging. The differential diagnosis of intra-articular pathology causing hip pain can be diverse. These includes conditions such as osteoarthritis, fracture, and avascular necrosis, synovitis, loose bodies, labral tears, articular pathology and, femoro-acetabular impingement. Magnetic resonance imaging (MRI) arthrography of the hip has been widely used now for diagnosis of articular pathology of the hip. A retrospective analysis of 113 patients who had MRI arthrogram and who underwent hip arthroscopy was included in the study. The MRI arthrogram was performed using gadolinium injection and reported by a single radiologist. The findings were then compared to that found on arthroscopy. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy and 95% confidence interval were calculated for each pathology. Labral tear—sensitivity 84% (74.3–90.5), specificity 64% (40.7–82.8), PPV 91% (82.1–95.8), NPV 48% (29.5–67.5), accuracy 80%. Delamination—sensitivity 7% (0.8–22.1), specificity 98% (91.6–99.7), PPV 50% (6.8–93.2), NPV 74% (65.1–82.2) and accuracy 39%. Chondral changes—sensitivity 25% (13.3–38.9), specificity 83% (71.3–91.1), PPV 52% (30.6–73.2), NPV 59% (48.0–69.2) and accuracy 58%. Femoro-acetabular impingement (CAM deformity)—sensitivity 34% (19.6–51.4), specificity 83% (72.2–90.4), PPV 50% (29.9–70.1), NPV 71% (60.6–80.5) and accuracy 66%. Synovitis—sensitivity 11% (2.3–28.2), specificity 99% (93.6–100), PPV 75% (19.4–99.4), NPV 77% (68.1–84.6) and accuracy 77%. Our study conclusions are MRI arthrogram is a useful investigation tool in detecting labral tears, it is also helpful in the diagnosis of femoro-acetabular impingement. However, when it comes to the diagnosis of chondral changes, defects and cartilage delamination, the sensitivity and accuracy are low.
