The current burden of diabetic foot disease.

Abstract: Neuropathy and ischaemia are two great pathologies of the diabetic foot which lead to the characteristic features of foot ulceration (neuropathic and ischaemic) and Charcot neuroarthropathy These can be complicated by infection and eventually may result in amputation (minor or major) and increased mortality All of these features contribute to considerable clinical and economic burden Peripheral nerves in the lower limbs are susceptible to different types of damage in patients with diabetes leading to distinctive syndromes These include symmetrical sensory neuropathy associated with autonomic neuropathy, which advances gradually, and acutely painful neuropathies and mononeuropathies which have a rather acute presentation but usually recover Ischaemia in the form of peripheral arterial disease is an important contributor to the burden of the diabetic foot The incidence of atherosclerotic disease is raised in patients with diabetes and its natural history is accelerated Diabetes causes severe and diffuse disease below-the knee The lifetime risk of developing a diabetic foot ulcer is between 19% and 34% Recurrence is common after initial healing; approximately 40% of patients have a recurrence within 1 year after ulcer healing, almost 60% within 3 years, and 65% within 5 years Charcot neuroarthropathy is characterised by bone and joint destruction on the background of a neuropathy Its prevalence in diabetes varies from 01% to 8% Infection develops in 50%–60% of ulcers and is the principal pathology that damages diabetic feet Approximately 20% of moderate or severe diabetic foot infections result in lower extremity amputations The incidence of osteomyelitis is about 20% of diabetic foot ulcers Every 20 s a lower limb is amputated due to complications of diabetes Of all the lower extremity amputations in persons with diabetes, 85% are preceded by a foot ulcer The mortality at 5 years for an individual with a diabetic foot ulcer is 25 times as high as the risk for an individual with diabetes who does not have a foot ulcer The economic burden exacted on health care systems is considerable and includes direct and indirect costs, with loss of personal earnings and burden to carers The diabetic foot is a significant contributor to the global burden of disability and reduces the quality of life It remains a considerable public health problem

The global burden of trauma during the COVID-19 pandemic: A scoping review.

Abstract: Purpose; The COVID-19 pandemic has necessitated profound adaptations in the delivery of healthcare to manage a rise in critically unwell patients. In an attempt to slow the spread of the virus nationwide lockdown restrictions were introduced. This review aims to scope the literature on the impact of the pandemic and subsequent lockdown on the presentation and management of trauma globally. Methods; A scoping review was conducted in accordance with PRISMA-ScR guidelines. A systematic search was carried out on the Medline, EMBASE and Cochrane databases to identify papers investigating presentation and management of trauma during the COVID-19 pandemic. All studies based on patients admitted with orthopaedic trauma during the COVID-19 pandemic were included. Exclusion criteria were opinion-based reports, reviews, studies that did not provide quantitative data and papers not in English. Results; 665 studies were screened, with 57 meeting the eligibility criteria. Studies reported on the footfall of trauma in the UK, Europe, Asia, USA, Australia and New Zealand. A total of 29,591 patients during the pandemic were considered. Mean age was 43.7 years (range <1-103); 54.8% were male. Reported reductions in trauma footfall ranged from 20.3% to 84.6%, with a higher proportion of trauma occurring secondary to interpersonal violence, deliberate self-harm and falls from a height. A decrease was seen in road traffic collisions, sports injuries and trauma occurring outdoors. There was no significant change in the proportion of patients managed operatively, and the number of trauma patients reported to be COVID-19 positive was low. Conclusion; Whilst the worldwide COVID-19 pandemic has caused a reduction in the number of trauma patients; the services managing trauma have continued to function despite infrastructural, personnel and pathway changes in health systems. The substantial effect of the COVID-19 pandemic on elective orthopaedics is well described, however the contents of this review evidence minimal change in the delivery of effective trauma care despite resource constraints during this global COVID-19 pandemic.

Coronavirus disease 2019 (COVID-19) markedly increased mortality in patients with hip fracture - A systematic review and meta-analysis.

Abstract: Introduction: This systematic review and meta-analysis aimed to evaluate the prevalence of coronavirus disease 2019 (COVID-19) and its impact on mortality in patients with hip fracture. Methods: We performed a systematic literature search in PubMed, Cochrane Central Database, and medRvix from inception up to July 13, 2020 on research articles that enrolled hip fracture patients who had information on COVID-19 and clinically validated definition of death. Results: A total of 984 participants from 6 studies were included in our study. The pooled prevalence of COVID-19 was 9% [95% CI: 7-11%]. The mortality rate in patients with concomitant hip fracture and COVID-19 was found to be 36% (95% CI: 26-47%), whereas the mortality rate in hip fracture without COVID-19 is 2% (95% CI: 1-3%). Meta-analysis showed that COVID-19 was associated with a seven-fold increase in risk (RR 7.45 [95% CI: 2.72, 20.43], p < 0.001; I2: 68.6%) of mortality in patients with hip fracture. Regression-based Harbord's test showed no indication of small-study effects (p = 0.06). Conclusion: The present meta-analysis showed that COVID-19 increased the risk of mortality in patients with hip fracture. Trial registration: This study is registered with PROSPERO, July 21, 2020, number CRD42020199618. Available from https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020199618.

Epidemiological pattern of orthopaedic fracture during the COVID-19 pandemic: A systematic review and meta-analysis.

Abstract: Introduction This systematic review and meta-analysis aimed evaluate the 30-day mortality, number and site of fracture, mechanism of injury, and location where injury was sustained during the pandemic compared to pre-pandemic. Methods We performed a systematic literature search from PubMed and Embase on original articles, research letters, and short reports which have data about the number of fractures, site of fracture, mechanism of injury, location where injury was sustained, percentage of operative intervention, mortality during the pandemic compared to a specified period of time before the pandemic. The search was finalized in October 14, 2020. Results A total of 11,936 participants from 16 studies were included in our study. The pooled analysis indicated a higher 30-days mortality associated with fractures during the pandemic (9% vs 4%, OR 1.86 [1.05, 3.27], p = 0.03; I2: 36%, p = 0.15). The number of fractures presenting to hospitals has declined 43% (35–50%) compared to pre-pandemic. Hand fracture was fewer during the pandemic (18% vs 23%, OR 0.75 [0.58, 0.97], p = 0.03; I2: 69%, p = 0.002). Work-related traumas, high-energy falls, and domestic accidents were more common during the pandemic, while sports-related traumas were found to be less. Injuries that occurred in the sports area were lower than before the pandemic. Conclusion The present meta-analysis showed that during the COVID-19 pandemic, the number of fractures has decreased, but there is a higher mortality rate associated with fractures.

SARS-CoV-2 and limb ischemia: A systematic review.

Abstract: Background Recent spread of severe acute respiratory coronavirus syndrome-2 (SARS-CoV-2) has led to the coronavirus disease (COVID-19) pandemic, resulting in new challenges across all medical specialties. Limb and digit ischemia have been associated with COVID-19 infection. This systematic review includes primary studies of COVID-19 limb ischemia to identify risk factors, comorbidities, case characteristics, and treatment strategies to better understand the nature of this disease and its effects on the extremities. Methods A literature search for studies detailing COVID-19 infected patients with limb or digit ischemia was performed, identifying 157 articles, 12 of which met inclusion criteria, accounting for 47 patients. Inclusion criteria were (1) primary studies, (2) positive disease diagnosis (3) limb ischemia, (4) reported treatment. Demographic data, case characteristics, treatments, outcomes and mortality were collected and pooled. Results The average patient age was 67.6 years, predominantly male (79.6%). Of the 44 cases discussing treatment, 13 (30%) patients underwent medical treatment alone, while 23 (52.3%) patients underwent medical plus surgical treatment. Four patients (9.1%) were treated with observation. In 10 of the 12 studies, lab findings, thrombosis, or conclusions supporting a hypercoagulable state as a cause of limb/digit ischemia were cited. Five patients (10.6%) were on vasopressors and 8 patients (17.0%) were on a ventilator. Of those treated with observation alone, there was 100% resolution of symptoms. Of those treated medically without surgical intervention (17 patients), 6 patients (35.3%) were reported to have revascularization, 6 patients (35.3%) died, and the remaining outcomes were not reported. Medical and surgical treatment resulted in one limb amputation (4.4%) and altogether 74% of patients achieved revascularization of the affected limb/digit. Mortality rate was 45%. Conclusions COVID-19 infection may be associated with increased risk of limb or digital ischemia, although the quality of evidence supporting this theory is limited. Evidence of inflammatory-mediated thrombosis and endothelial injury are possible explanations which would support the use of immunotherapy in addition to anticoagulation for treatment or prevention of thromboembolic events. Current outcomes and treatment strategies are variable. Level of evidence IV.

How hand and wrist trauma has changed during covid-19 emergency in Italy: Incidence and distribution of acute injuries. What to learn?

Abstract: Background the purpose is to gather and analyze the statistical datas of wrist and hand injuries admitted to the Hand and Reconstructive Microsurgery and Replantation Hub center of Careggi Hospital, Florence during the first two months of COVID-19 epidemic in Italy. The Authors investigated how the drastic changes in daily activities modified the epidemiology of hand trauma lesions. Methods The Authors analyzed the characteristics of hand and wrist traumatic disorders during the months of February and March comparing 2019 to 2020. Collected data included age distribution, traumatic etiology, diagnosis and type of surgical procedures. Results The total number of orthopedic and trauma patients significantly decrease in 2020 compared to 2019 (3360 vs 1470). The number of hand and wrist injuries didn’t show a significant difference between 2019 and 2020 instead (192 vs 131). The overall number of patients hospitalized and surgically treated at our Operative Unit (OU) was 168 in 2019 and 120 in 2020. Male patients resulted prevalent (60,7 M vs 39,3F/2019; 63,2 M vs 36,8F/2020). In terms of patient age, in 2020 we registered a significant reduction of cases in the 20-35-year-old age group and a significant increase in the 51–65 and 66-80-year-old age groups. Traffic-related, sport-related and fortuitous injuries significantly decreased in 2020, while the number of domestic accidents significantly increased. Analyzing the Hospital Discharge Records (HDR), we found a significant increase in the number of proximal and middle phalanx fractures; no significant differences were found for other kinds of discharge diagnosis. As for the choice of surgical treatment options, no differences were found between 2019 and 2020. Conclusion Even during drastic movement restrictions and the prolonged suspension of work and leisure activities secondary to COVID-19 epidemic in 2020, hand and wrist traumas rate remained almost the same compared to the same period of the previous year. Nevertheless, a significant change in the etiology and patient age was registered. In fact, sport and traffic-related traumas decreased respect to domestic traumas, while the previous prevalent involvement of young adults was surpassed by accidental hand traumas in the elderly and active adults.

The protective role of glutathione in osteoarthritis.

Abstract: It is currently understood that osteoarthritis (OA) is a major chronic inflammatory musculoskeletal disease. While this disease has long been attributed to biomechanical trauma, recent evidence establishes a significant correlation between osteoarthritic progression and unbridled oxidative stress, responsible for prolonged inflammation. Research describes this as a disturbance in the balanced production of reactive oxygen species (ROS) and antioxidant defenses, generating macromolecular damage and disrupted redox signaling and control. Since ROS pathways are being considered new targets for OA treatment, the development of antioxidant therapy to counteract exacerbated oxidative stress is being continuously researched and enhanced in order to fortify the cellular defenses. Experiments with glutathione and its precursor molecule, N-acetylcysteine (NAC), have shown interesting results in the literature for the management of OA, where they have demonstrated efficacy in reducing cartilage degradation and inflammation markers as well as significant improvements in pain and functional outcomes. Glutathione remains a safe, effective and overall cheap treatment alternative in comparison to other current therapeutic solutions and, for these reasons, it may prove to be comparably superior under particular circumstances. Methods Literature was reviewed using PubMed and Google Scholar in order to bring up significant evidence and illustrate the defensive mechanisms of antioxidant compounds against oxidative damage in the onset of musculoskeletal diseases. The investigation included a combination of keywords such as: oxidative stress, oxidative damage, inflammation, osteoarthritis, antioxidant, glutathione, n-acetylcysteine, redox, and cell signaling. Conclusion Based on the numerous studies included in this literature review, glutathione and its precursor N-acetylcysteine have demonstrated significant protective effects in events of prolonged, exacerbated oxidative stress as seen in chronic inflammatory musculoskeletal disorders such as osteoarthritis.

Damage control orthopaedics in polytraumatized patients- current concepts.

Abstract: The principles of fracture management in patients with multiple injuries continue to be of crucial importance. Early treatment of unstable polytraumatized patients with head, chest, abdomen or pelvic injuries, with blood loss followed by immediate fracture fixation (Early Total Care -ETC) may be associated with secondary life threatening posttraumatic systemic inflammatory response syndrome (SIRS). Development of SIRS is typically a function of the type and severity of the initial injury (the "first hit"). Immediate Fracture fixation, using reamed nails or plates, in such unstable patients with multiple injuries is subsequently defined as the "second hit" and may be associated with development of acute respiratory distress syndrome (ARDS) and multiple organ failure (MOF), with relatively high morbidity and mortality. The other alternative for long bone fracture fixation in unstable polytraumatized patients is based on immediate treatment of life threatening conditions related to the injuries, followed by the initial use of minimally invasive modular external frames for long bone fractures and is called Damage Control Orthopedics (DCO) and is widely accepted. In order to refine the DCO concept and to avoid an overuse of external fixation, the "Safe Definitive Surgery" (SDS) concept has been introduced, which is a dynamic synthesis of both strategies (ETC and DCO). The SDS strategy employs clinical parameters and includes repeated assessment of patients. The following paper is going to summarize historical backgrounds and recent concepts in treatment of polytraumatized patients.

Cement augmentation for trochanteric fracture in elderly: A systematic review.

Abstract: Background Cement augmentation of internal fixation of hip fracture has reported to improve fracture stability in osteoporotic hip fractures, reducing the risk of cut-out of the sliding screw through the femoral head. The purpose of present study was to perform a systematic literature review on the effects of augmentation technique in patients with osteoporotic hip fractures. Material and methods A comprehensive literature search was systematically performed to evaluate all papers published in English language included in the literature between January 2010 and July 2020, according to the PRISMA 2009 guidelines. In vivo and in vitro studies, case reports, review articles, cadaveric studies, biomechanical studies, histological studies, oncological studies, technical notes, studies dealing with radiological classifications and studies on revision surgery were excluded. Results A total of 5 studies involving 301 patients were included. Patients had a mean age of 84.6 years and were followed up for a mean period of 11 months. The proximal femoral fractures were stabilized with implantation of the PFNA or Gamma nail and augmentation was performed with two different cements: polymethylmethacrylate (PMMA) in 4 studies and calcium phosphate (CP) in one study. Overall, 57.5% of patients reached the same or greater preoperative mobility, and postoperative Parker Mobility Score and Harris Hip Score were acceptable. No significantly complications were observed, and no additional surgery related to the implant was required. Conclusion The results of this systematic review show that cement augmentation is a safe and effectiveness method of fixation to treat trochanteric fractures.

Additive manufacturing of porous titanium metaphyseal components: Early osseointegration and implant stability in revision knee arthroplasty.

Abstract: Aims Metaphyseal cones and sleeves are components used in revision knee arthroplasty to ensure load transfer, encourage bone on-growth and prevent stress shielding. Additive manufacturing of titanium alloy implants is a novel technique with limited clinical outcome reports in the literature. The aim of this study was to determine radiographic evidence of osseointegration and early results of a single manufacturer porous titanium metaphyseal components in the proximal tibia. Methods We retrospectively reviewed the prospectively collected database of two institutions. Patients who underwent revision knee arthroplasty using porous titanium components by a single manufacturer were identified. Immediate post-operative and latest follow-up radiographs were independently analysed by 2 reviewers to determine metaphyseal bone contact and level of osseointegration in relevant Knee Society Radiographic Evaluation and Scoring System zones. Results 22 patients (15 males; 7 females) with a mean age of 71 (49–92) years were included. The mean follow-up period was 14 months (2–44 months). Cones were used in 16 patients and sleeves in 6. Interobserver reliability assessment showed substantial agreement (weighted Kappa 0.71, (95% CI: 0.60, 0.81). There was significant correlation between the bone contact in the immediate postop radiograph and osseointegration at final follow-up (kendall’s tau-b: 0.698, p Conclusion Porous titanium metaphyseal components produced with additive manufacturing provided excellent osseointegration and no early clinical failures. Partial or complete contact of the cone with native bone in the immediate postoperative radiograph resulted in osseointegration in all cases.

Biomechanical study of different internal fixations in Pauwels type III femoral neck fracture - A finite elements analysis.

Abstract: Objective To evaluate biomechanical behavior of different internal fixation methods for the treatment of Pauwels Type III femoral neck fractures. Methods Three internal fixators were developed to treat Pauwels Type III femoral neck fracture using finite elements: dynamic hip screw (DHS); DHS combined with anti-rotation screw; three cannulated screws in an inverted triangular configuration (ASNIS). Under the same conditions, vertical fracture displacement, and maximum and minimum principal, and Von Mises stresses were evaluated. Results The vertical displacements evaluated were: 5.43 mm, 5.33 mm and 6.22 mm, rotational displacements values were 1.1 mm, 0.4 mm and 1.3 mm; maximum principle stress values obtained for the upper region of the femoral neck were 3.26 hPa, 2.77 hPa, and 4.5 hPa, minimum principal stress values obtained for the inferior region of the femoral neck were −1.97 hPa, −1.8 hPa and t −3.15 hPa; Von Mises peak stress values were 340.0 MPa, 315.5 MPa and 326.1 Mpa, for DHS, DHS with anti-rotation device, and ASNIS, respectively. Conclusion: The DHS combined with anti-rotation screw yielded better results in terms of rotational and vertical displacements, traction and compression distributions on fractures, and Von Mises stress, demonstrating mechanical superiority for Pauwels Type III fracture.

Conservative surgery for chronic diabetic foot osteomyelitis: Procedures and recommendations.

Abstract: Osteomyelitis (OM) is the most frequent infection associated with diabetic foot ulcers (DFU) that typically involve the forefoot, the most common location of DFU. Conservative surgical procedures could be attractive alternative that reduces minor and major amputations and avoid future recurrence thus preserving the functionally of the foot. This review aimed to analyze and describe the current evidence on conservative diabetic foot osteomyelitis (DFO) surgical procedures depending on DFU location and indications. A narrative revision of the evidence was carried out by searching Medline through PubMed databases from inception to late July 2020 to identify retrospective, prospective, and randomized controlled trials pertaining to conservative DFO procedures on the forefoot. Seven types of conservative surgical procedures for DFO treatment in the forefoot are described in this review: (1) partial or total distal phalangectomy, (2) arthroplasty of the proximal or distal interphalangeal joint, (3) distal Syme amputation, (4) percutaneous flexor tenotomy, (5) sesamoidectomy, (6) arthroplasty of the metatarsophalangeal joint, and (7) metatarsal head resection. When indicated, conservative surgery for DFUs in patients with chronic forefoot OM is a safe and effective option that increases the chances of healing and reduces the possibility of limb loss and death compared with radical amputation procedures. Since a lack of sufficient evidence supporting this procedure exists, future investigations should be focused on the random clinical trial (RCT) design. The results of prospective trials could help surgeons select the appropriate procedure in each case in order to minimize complications.

Coccydynia-A comprehensive review on etiology, radiological features and management options

Abstract: Coccydynia is a disabling condition characterized by pain in the coccyx region of the spine. The first description of the disease was given in as early as 1859. Since then a number of theories have been proposed by various researchers to explain the pathogenesis of the disease. Treatment options for coccydynia include ergonomic adaptation, manual therapy, injections and surgery. Despite being identified as a disease as early as 18th century, several uncertainties with respect to the origin of pain, predisposing factors and treatment outcomes of a wide range of treatment options persist till date. The current narrative review presents various aspects of the disease including pathoanatomy, clinical presentation, radiological features and management options for the disease.

Article processing charge may be a barrier to publishing.

Abstract: Recently most of the journals charge a fee known as article processing charge (APC) for publication of an article. These charges can vary from journal to journal. This publication fee is often paid by the author, the author's institution, or their research funder organization. Though low- and middle-income countries are usually exempted from APC, India does not come under the category of waiver by most of the journals that ask for the APC. Most of the Indian institutes do not pay for publication and research thus individual researcher suffers huge financial burden due to APC. Hence, less affluent institutions, scholars, and students are unable to publish their work due to these barriers. These articles highlight the challenges faced by authors and solutions for publishers and journals to avoid APCs.

Comparative outcome analysis of spinal anesthesia versus general anesthesia in lumbar fusion surgery

Abstract: Introduction Spinal anesthesia (SA) has been shown in several studies to be a viable alternative to general anesthesia (GA) in laminectomies, discectomies, and microdiscectomies. However, the use of SA in spinal fusion surgery has been very scarcely documented in the current literature. Here we present a comparison of SA to GA in lumbar fusion surgery in terms of perioperative outcomes and cost. Methods The authors retrospectively reviewed the charts of all patients who underwent 1- or 2-level minimally invasive transforaminal lumbar interbody fusion (TLIF) surgery by a single surgeon, at a single institution, from 2015 to 2018. Data collected included demographics, operative and recovery times, nausea/vomiting, postoperative pain, and opioid requirement. Costs were included in the analysis if they were: 1) non-fixed; 2) incurred in the operating room (OR); and 3) directly related to patient care. All cost data represents net costs and was obtained from the hospital revenue cycle team. Patients were grouped for statistical analysis based on anesthetic modality. Results A total of 29 patients received SA and 46 received GA. Both groups were similar in terms of age, gender, BMI, number of levels operated upon, preoperative diagnosis, and medical comorbidities. The SA group spent less time in the OR (163.86 ± 9.02 vs. 195.63 ± 11.27 min, p Discussion/conclusion To our knowledge, SA is almost never used in lumbar fusion, and a cost-effectiveness comparison with GA has not been recorded. In this retrospective study, we demonstrate that the use of SA in lumbar fusion surgery leads to significantly shorter operative and recovery times, less postoperative pain and opioid usage, and slight cost savings over GA. Thus, we conclude that this anesthetic modality represents a safe and cost-effective alternative to GA in lumbar fusion.

Does racial background influence outcomes following total joint arthroplasty

Abstract: Background The purpose of this study is to assess whether racial differences influence patient-reported outcome measures (PROMs) following primary total hip (THA) and knee (TKA) arthroplasty. Methods We retrospectively reviewed patients who underwent primary THA or TKA from 2016 to 2020 with available PROMs. Both THA and TKA patients were separated into three groups based on their ethnicity: Caucasian, African-American, and other races. Patient demographics, clinical data, and PROMs at various time-periods were collected and compared. Demographic differences were assessed using chi-square and ANOVA. Univariate ANCOVA was utilized to compare outcomes and PROMs while accounting for demographic differences. Results This study included 1999 THA patients and 1375 TKA patients. In the THA cohort, 1636 (82%) were Caucasian, 177 (9%) were African-American, and 186 (9%) were of other races. In the TKA cohort, 864 (63%) were Caucasian, 236 (17%) were African-American, and 275 (20%) were of other races. Surgical-time significantly differed between the groups that underwent THA (88.4vs.100.5vs.96.1; p < 0.001) with African-Americans requiring the longest operative time. Length-of-stay significantly differed in both THA (1.5vs.1.9vs.1.8; p < 0.001) and TKA (2.1vs.2.5vs.2.3; p < 0.001) cohorts, with African-Americans having the longest stay. Caucasians reported significantly higher PROM scores compared to non-Caucasians in both cohorts. All-cause emergency-department (ED) visits, 90-day postoperative events (readmissions&revisions), and discharge-disposition did not statistically differ in both cohorts. Conclusion Non-Caucasian patients demonstrated lower PROM scores when compared to Caucasian patients following TJA although the differences may not be clinically relevant. LOS was significantly longer for African-Americans in both THA and TKA cohorts. Further investigation identifying racial disparity interventions is warranted. Level of evidence Prognostic Level III.

Aerosol generating procedures in orthopaedics and recommended protective gear.

Abstract: The prime of COVID-19 forced institutions and hospitals to convert operating rooms into intensive care units. Now as the disease prevalence drops and plateaus in several countries, elective surgeries are being slowly resuming. Such that asymptomatic carriers too would approach hospitals for surgical needs. Coronaviruses are understood to transmit both by droplets and aerosols. Orthopaedic surgery requires regular use of high-speed instruments like power drills, oscillating saws and burrs. Several medical procedures are known to create aerosols thereby exposing the surgeon to contract the virus. Adequate know-how and protective means are mandatory to safeguard the surgical team from inevitable exposure.

Do preoperative intra-articular corticosteroid and hyaluronic acid injections affect time to total joint arthroplasty?

Abstract: Introduction Intra-articular corticosteroid (CSI) or hyaluronic acid (HAI) injections alleviate symptoms of osteoarthritis in patients who may be candidates for total hip or total knee arthroplasty (THA/TKA). However, their effect on time to total joint arthroplasty (TJA) and complications remains uncertain. We sought to evaluate (1) delay in time to surgery for patients receiving injections prior to THA/TKA (2) incidence of patients that receive injections, (3) type and number of injections, and (4) compare complication rates between patients with and without injections. Methods We retrospectively reviewed 3340 consecutive TJA (1770 THA and 1570 TKA). Patients were divided into two cohorts depending if they received preoperative intra-articular injection or not. We identified dates of first clinic presentation and index surgery, injection type, total administered, and 90-day complications, including periprosthetic joint infection. Results 150/1770 THA and 192/1570 TKA patients received injections (8.5%vs.12.2%,p = 0.0004). Time from first presentation to clinic to TJA was significantly greater in patients receiving injections [12.4 ± 11 months vs.7.3 ± 10.7,p Conclusion Injections are associated with an increased time to TJA by a statistically significant amount, however its clinical significance is debatable. Injections are safe if administered at least three months preoperatively. If patients present with appropriate surgical indications and are ready, we do not recommend intra-articular injections to delay surgery.

Evolving concepts and strategies in the management of polytrauma patients

Abstract: Major trauma is one of the leading causes of morbidity and mortality in young adults. The impact of disability on the quality of life and functionality in this younger population is worrisome. This remains a major public health concern across the globe. Immediate and early deaths account for nearly 80% of trauma deaths occurring within the first few hours of injury to the first few days, usually because of traumatic brain injury or major exsanguination and subsequently due to shock or hypoxia. Worldwide adoption of comprehensive trauma systems and evolving models of trauma care including prehospital interventions have led improvements in trauma and critical care over the last few decades. Resuscitation and damage control orthopaedics are two key pillars in the management of polytrauma patient. Trauma-related coagulopathy can be an emerging complication during resuscitation of such patients which should be recognized early so appropriate corrective measures can be undertaken. We describe the evolving models of care in the management of polytrauma and trauma associated coagulopathy.

Smart sensor implant technology in total knee arthroplasty.

Abstract: Innovations in computer technology and implant design have paved the way for the development of smart instruments and intelligent implants in trauma and orthopaedics to improve patient-related functional outcomes. Sensor technology uses embedded devices that detect physical, chemical and biological signals and provide a way for these signals to be measured and recorded. Sensor technology applications have been introduced in various fields of medicine in the diagnosis, treatment and monitoring of diseases. Intelligent 'Smart' implants are devices that can provide diagnostic capabilities along with therapeutic benefits. In trauma and orthopaedics, applications of sensors is increasing because of the advances in microchip technologies for implant devices and research designs. It offers real-time monitoring from the signals transmitted by the embedded sensors and thus provides early management solutions. Smart orthopaedic implants have applications in total knee arthroplasty, hip arthroplasty, spine surgery, fracture healing, early detection of infection and implant loosening. Here we have explored the role of Smart sensor implant technology in total knee arthroplasty. Smart sensor assisted can be used intraoperatively to provide objective assessment of ligament and soft tissue balancing whilst maintaining the sagittal and coronal alignment to achieve desired kinematic targets following total knee arthroplasty. It can also provide post-implantation data to monitor implant performance in natural conditions and patient's clinical recovery during rehabilitation. The use of Smart Sensor implant technology in total knee arthroplasty appears to provide superior patient satisfaction rates and improved functional outcomes.

Orthopedic fracture hospitalizations are revving up from E-Scooter related injuries.

Abstract: Introduction Due to market expansion of electric-scooter companies, a significant rise of personal e-scooter use in dense, urban communities has been observed. No literature has specifically focused on e-scooter fracture epidemiology and risk factors associated with direct hospital admission. The aims of this study were to evaluate the 1) patterns of e-scooter related orthopaedic fractures 2) risk factors associated with direct hospital admission. Materials and methods A retrospective review of National Electronic Injury Surveillance System (NEISS) from the United States between 2015 and 2019 was utilized to identify e-scooter fracture epidemiology. Uni/multivariable analyses were conducted to identify independent variables associated with direct hospital admission. Results 5,016 patients were identified. The most common fracture location was the upper extremity (25.4%). Multiple distinct fractures diagnoses (p Discussion This study highlights that e-scooter fracture related injuries continue to progress, and without appropriate educational and public health efforts, these injuries will continue to rise.

Carbon fibre reinforced PEEK versus traditional metallic implants for orthopaedic trauma surgery: A systematic review.

Abstract: Introduction There is no literature review comparing outcomes of fixation using carbon-fibre-reinforced polyetheretherketone (CFR PEEK) compared to metal implants used in orthopaedic extremity trauma surgery. A systematic review was performed to compare CFR PEEK to metal implants for clinically-important fracture outcomes. Methods A search of the online databases of PubMed/Medline, EMBASE and Cochrane Database was conducted. A systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A meta-analyses was performed for functional outcomes in proximal humerus fractures converting the score differences to standard mean difference units. GRADE approach was used to determine the level of certainty of the estimates. Results Two prospective randomised controlled trials and seven comparative observational studies with a total of 431 patients were included. Of the nine studies included, four compared the use of CFR PEEK against metal plates in proximal humerus fractures. Aggregated functional scores across the proximal humerus studies, there was a small signal of better improvement with CFR PEEK (SMD 0.22, 95% CI -0.03 to 0.47, p = 0.08, low certainty). Greater odds of adverse events occurred in the metal group (OR 2.34, 95% CI 0.73 to 7.55, p = 0.15, low certainty). Conclusions Low to very low certainty evidence suggests a small improvement in functional recovery with CFR PEEK in proximal humerus fractures. This may be mediated through a small reduction in major adverse events related to fracture healing and stability.

Outcomes of total joint arthroplasty in patients with depression: A systematic review.

Abstract: Background Depression has been implicated as a poor predictor of outcomes after total joint arthroplasty (TJA) of the lower extremity in some studies. We aimed to determine whether depression as a comorbidity affects the TJA outcomes and whether pain reduction associated with successful TJA alters depressive symptoms. Methods A search of PUBMED was performed using keywords “depression”, “arthroplasty”, “depressive disorder”, and “outcomes.” All English studies published over the last ten years were considered for inclusion. Quantitative and qualitative analysis was then performed on the data. Results Thirty articles met inclusion criteria (16 retrospective, 14 prospective). Three showed that depressed patients were at higher risk for readmission. Two reported that depressed patients had higher likelihood of non-home discharge after TJA compared to non-depressed patients. Four noted that depressed patients incur higher hospitalization costs than non-depressed patients. Ten suggest depression is a predictor of poor patient-reported outcome measures, pain, and satisfaction after TJA. Five suggested the gains depressed patients experience in functional outcome scores after TJA are similar to gains experienced by patients without depression. Another eight suggested that TJA improves not only function and pain but also depressive symptoms in patients with depression. Conclusion The results of this review show that depression increases the risk of persistent pain, dissatisfaction, and complications after TJA. Additionally, depressed patients may incur higher costs than non-depressed patients undergoing TJA and may have worse preoperative and postoperative patient reported outcome measures (PROMs). However, the gains in function that depressed patients experience after TJA are equivalent to gains experienced by non-depressed patients and depressed patients may experience improvement in their depressive symptoms after TJA. Patient selection for TJA is critical and counseling regarding increased risk for complications is crucial in depressed patients undergoing TJA.

Polytrauma management - What is new and what is true in 2020 ?

Abstract: This is a review of changes in the practice of treating polytrauma managemtent within the years prior to 2020. It focuses on five different topics, 1. The development of an evidence based definition of Polytrauma, 2. Resuscitation Associated Coagulopathy (RAC), 3. neutrophil guided initial resuscitation, 4. perioperative Scoring to evaluate patients at risk, and 5. evolution of fracture fixation strategies according to protocols1,2 (Early total care, ETC, damage control orthopedics, DCO, early appropriate care, EAC, safe definitive surgery, SDS).

A look at the global impact of SARS CoV-2 on orthopedic services.

Abstract: Background The COVID-19 pandemic profoundly impacted healthcare institutions worldwide. Particularly, orthopedic departments had to adapt their operational models. Purpose This review aimed to quantify the reduction in surgical and outpatient caseloads, identify other significant trends and ascertain the impact of these trends on orthopedic residency training programs. Methods Medline and Embase were searched for articles describing case load for surgeries, outpatient clinic attendance, or emergency department (ED) visits. Statistical analysis of quantitative data was performed after a Freeman-Tukey double arcsine transformation. Results were pooled with random effects by DerSimonian and Laird model. When insufficient data was available, a systematic approach was used to present the results instead. Results A total of 23 studies were included in this study. The number of elective surgeries, trauma procedures and outpatient attendance decreased by 80% (2013/17400, 0.20, CI: 0.12 to 0.29), 47% (3887/17561, 0.53, CI: 0.37 to 0.69) and 63% (84174/123967, 0.37, CI: 0.24 to 0.51) respectively. During the pandemic, domestic injuries and polytrauma increased. Residency training was disrupted due to diminished clinical exposure and changing teaching methodologies. Additionally, residents had more duties which contributed to a lower quality of life. Conclusions The COVID-19 pandemic has made an unprecedented impact on orthopedics departments worldwide. The slow return of orthopedic departments to normalcy and the compromised training of residents due to the pandemic points to an uncertain future for healthcare institutions worldwide, wherein the impact of this pandemic may yet still be felt far in the future.

Traumatic rotator cuff tears - Current concepts in diagnosis and management

Abstract: Rotator cuff tears represent one of common shoulder pathologies presenting over a wide spectrum of age groups and varying presentation. Typically, rotator cuff tears occur more frequently in elderly than in younger patients, following a chronic or acute-on-chronic course and usually secondary to due to tendon degeneration. Though there has been a considerable debate in the literature of the terms "acute" and "traumatic" used in the classification of rotator cuff tears, there appears to be consensus about the need for early diagnosis to facilitate prompt surgical treatment and the improve patient outcome. Significant differences in rotator cuff tears between those occurring in younger and older patients could be due to mechanism of injury, presentation, severity of the tear, biological healing potential and rehabilitation. Acute traumatic rotator cuff tears especially in younger age group represent a distinct entity from other patterns of rotator cuff tears. Consequently, a high index of suspicion, focused clinical examination, complementary imaging is a pre-requisite for an early diagnosis and effective management. We analyze the biomechanical consequences of acute rotator cuff tears along with characteristic mechanism of injury and spectrum of tendon involvement. The evolving concepts in the diagnosis and management of these distinct injuries are discussed with review of current literature.

Injuries associated with arm wrestling: A narrative review.

Abstract: Objective Arm wrestling is common sport amongst amateur enthusiasts. Multiple injuries are described as a result of the sport. The authors present a narrative review of the common injuries associated with the sport. Design Systematic review with a critical appraisal of the literature and a narrative review of the injuries associated with arm wrestling. Data sources Seven electronic databases were systematically searched using medical subject headings (MeSH) terms as follows. Arm wrestling, Indian Wrestling, Fractures, Injury, Ligament Injury with Boolean search terms “AND”. An extensive review of orthopaedic textbooks was also performed. Eligibility criteria for selecting studies Inclusion criteria were publications which included patients who suffered bony or soft tissue injuries as a result of arm wrestling published in English language. Results A total of 152 patients was seen across all studies. Spiral fractures of the distal third of the humerus are by far the most common injury reported in the setting of arm wrestling. The humerus fails due torsional and bending stresses. 23% were complicated by medial butterfly fragment and the incidence of radial nerve palsy was 23%. Fracture patterns differ in the skeletally immature arm wrestler, who show an increased incidence of medial humeral epicondyle fractures. We also report on the atypical fracture and soft tissue injury patterns that present.

The changing face of central chondrosarcoma of bone. One UK-based orthopaedic oncology unit's experience of 33 years referrals.

Abstract: Aim To ascertain the changing incidence over time of the three commonest primary sarcomas of bone. Data obtained with particular reference to central chondrosarcoma from the annual referral rate to a large UK-based specialist orthopaedic oncology unit. To discuss how the “barnyard pen” analogy of cancers previously applied to certain commoner cancers can also be applicable to central chondrosarcoma (CS) of bone. Materials and methods A retrospective review was conducted of a computerised database identifying all central cartilage tumours (CCT) of bone, including enchondroma and CS subtypes, between 1985 and 2018. These were compared with the referrals of the other two commonest primary sarcomas of bone, osteosarcoma and Ewing sarcoma. Results There was a total of 1507 CS showing a 68% overall increase in annual referral rate/incidence over the study period. 68% cases were the borderline malignant lesions now known as atypical cartilaginous tumour (ACT). The annual referral rate/incidence of this entity increased by 194% over the 30 years. Whereas, the annual referral rate/incidence for osteosarcoma and Ewing sarcoma was static for the past 20 years. Conclusion The annual incidence of central CS of bone showed a marked increase over the 33-year period as compared with both osteosarcoma and Ewing sarcoma. This is especially in the ACT category and is thought to be due to the increased provision of MRI scanning flagging up a rise in incidental findings. The spectrum of CCTs from benign to highly malignant elegantly fits the “barn yard” pen analogy and could prove useful as an explanatory tool for patients and clinicians unfamiliar with these diseases.

Myositis ossificans revisited - The largest reported case series.

Abstract: Introduction Myositis ossificans (MO) is a condition characterised by the formation of non-neoplastic heterotropic ossification in extraskeletal soft tissues. Material and methods We performed a retrospective study of our radiology databases within our tertiary orthopaedic centre to identify all cases of MO, reported on X ray, Magnetic resonance imaging (MRI) and Computed tomography (CT) over the past 13 years (2007–2020). Results We identified 68 cases of MO, which were included into our cohort. The average age of our patients was 36 years (range 4–84 years). 73% of cases (n = 50) were found to affect the lower limb muscles with the majority in the quadriceps. Conclusion We report the largest case series of MO and discuss the demographics, diagnoses and management.
