Spinal muscular atrophy and anorexia nervosa: a case report.

BACKGROUND: Spinal muscular atrophy (SMA) is an autosomal recessive condition affecting lower motor neurons causing progressive muscle atrophy. Anorexia nervosa (AN) is a psychiatric disorder characterised by intense fear of weight gain, restriction of energy intake, and preoccupation with body weight and shape. Low weight, gastrointestinal dysmotility, and respiratory infections are common in SMA but may mask AN. No paediatric cases of AN in SMA have been reported to date. CASE PRESENTATION: A 14-year-old female with SMA2 presented with 12 months of declining body weight to a nadir of 24.8 kg (BMI 11). This was initially attributed to medical complications including pneumonia and gastroenteritis, and chronic gut dysmotility associated with SMA. Despite almost 2 years of dietetic input and nutritional supplementation due to the weight plateauing from age 11, no significant restoration or gain was achieved. The Eating Disorder Examination-Questionnaire (EDE-Q) indicated a possible eating disorder and psychiatric evaluation confirmed AN. Initial management prioritised close medical monitoring and outpatient weight restoration on an oral meal plan. Skin fold anthropometric measurement was conducted to determine a minimum healthy weight. Individual psychological therapy and family sessions were undertaken. The patient developed major depression and a brief relapse with weight loss to 28 kg. Since then, the patient has maintained a weight of around 35 kg with stable mood. CONCLUSIONS: Low body weight, feeding issues, gastrointestinal dysmotility, and respiratory infections are common in SMA and diagnostic overshadowing can lead to delayed recognition of anorexia nervosa. Change to growth trajectory and prolonged weight loss should prompt consideration of comorbid psychiatric issues. Screening measures such as the EDE-Q and DASS may be helpful in this population. Close liaison between the neurogenetics and psychiatry teams is helpful. Skin fold anthropometry can assist in identifying a minimum healthy weight range.

Safety of expedited-surgery protocols in anticoagulant-treated patients with hip fracture: a systematic review and meta-analysis.

BACKGROUND: Perioperative management of patients with hip fracture patients receiving oral anticoagulants requires navigating the risks associated with surgical delay and perioperative hemostasis. The aim of this systematic review and meta-analysis was to evaluate the effect of expedited-surgery protocols on time to surgery and perioperative outcomes in anticoagulant-treated patients with hip fracture. METHODS: We searched MEDLINE, Embase and CENTRAL from inception to May 5, 2020, to identify English-language studies reporting outcomes after expedited hip fracture surgery in patients receiving vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs) before hospital admission. We performed a meta-analysis using Mantel-Haenszel weighting for dichotomous variables and inverse variance weighting for continuous variables. RESULTS: Among the 4253 citations identified, 14 studies were included. In the 6 studies eligible for meta-analysis, compared to hip fracture surgery before implementation of a VKA-reversal protocol, surgery after implementation of such a protocol was associated with a significant reduction in time to surgery (mean difference 45.31 h, 95% confidence interval [CI] 15.81 h to 74.80 h). Expedited surgery (within 48 h) in patients who received DOACs preoperatively was not associated with increased surgical duration (mean difference -7.29 min, 95% CI -22.5 min to 7.95 min) or 30-day mortality (odds ratio [OR] 1.30, 95% CI 0.49 to 3.89) compared to patients who did not receive anticoagulants (control patients). However, expedited surgery in DOAC-treated patients was associated with an increased blood transfusion risk compared to control patients (OR 0.58, 95% CI 0.36 to 0.96). CONCLUSION: Implementing a VKA-reversal protocol for patients with hip fracture is effective in decreasing time to surgery, without an increased bleeding risk. Performing hip fracture surgery within 48 hours in DOAC-treated patients is also safe, with a small increase in blood transfusion risk.

Transforming the journey together: Baseline findings from a longitudinal, co-designed study on psychiatry trainee experiences of training and wellbeing.

OBJECTIVE: Junior doctors have high rates of burnout resulting in downstream impacts on patient care. The aim of this study is to capture cross-sectional data on a cohort of psychiatry trainees. These data will be used to inform a wider project investigating psychiatry trainee mental health and wellbeing. METHOD: This paper reports on the 2019 baseline data of psychiatry trainees enrolled in a formal education course at the University of Sydney, Australia. The data were collected with an online survey using a range of validated mental health and wellbeing scales. This descriptive study involved psychiatry trainees as co-designers. RESULTS: Our research findings are in keeping with the existing literature on the poor mental health and wellbeing of doctors with significantly higher levels of anxiety and exhaustion found in female trainees and carers. Despite this, the cohort had high scores on the flourishing scale. CONCLUSIONS: Concern around the wellbeing of junior doctors in Australia appears justified. We need to move beyond focussing on individual action to systems-based approaches to improving wellbeing and ongoing sustainability of the psychiatry trainee workforce in NSW.

Venous thromboembolism rates in patients with bone and soft tissue sarcoma of the extremities following surgical resection: A systematic review.

BACKGROUND: Patients undergoing an orthopedic surgery for bone or soft tissue sarcoma are at increased venous thromboembolism (VTE) risk. Unfortunately, there is a lack of thromboprophylaxis guidelines in this population. The purpose of this systematic review was to determine the soft tissue and bone sarcoma VTE rate and to explore the thromboprophylaxis regimens used. METHODS: The databases MEDLINE, EMBASE, and CENTRAL were queried using keywords related to VTE and long bone malignancy requiring surgical intervention to 2020. Included studied reported VTE rate in patients with surgically managed extremity sarcoma. Descriptive statistics and weighted mean totals were calculated. RESULTS: A total of 2082 studies were screened and 23 studies were included. The overall VTE rate was 2.9%, with a rate of 3.7% and 1.4% in patients with bone and soft tissue sarcomas, respectively. Low-molecular-weight heparin was the most commonly used chemoprophylaxis. CONCLUSIONS: There is a high VTE rate following sarcoma surgery. The VTE rate is higher in bone sarcoma surgery, which may be attributed to differences in surgery and postoperative recovery. There was no consensus on the duration or type of thromboprophylaxis used. Future research is needed to determine the most effective thromboprophylaxis regimen in patients with sarcoma and whether individualized thromboprophylaxis is required.

Thromboembolic complications after surgical fixation of bone metastases: A systematic review.

BACKGROUND: Patients undergoing a major orthopedic surgery for metastatic bone disease (MBD) are at high risk of developing venous thromboembolic (VTE) complications. Despite concerns, there is no consensus on the most effective strategy to prevent VTE in these patients. The purpose of this systematic review was to determine the VTE rate following the surgical management of MBD. METHODS: The databases MEDLINE, EMBASE, and CENTRAL were searched using keywords related to VTE and MBD requiring surgical management. Included studies reported VTE rates in patients with surgically managed MBD. Descriptive statistics and weighted mean totals were calculated. RESULTS: In total, 2082 abstracts were screened, and 29 studies were included. The overall VTE rate was 4.7%. Patients receiving surgery for impending pathologic fracture had a higher rate of VTE (5.6%) compared to patients with acute pathologic fractures (4.2%). Low-molecular-weight heparin was the most used chemoprophylaxis. CONCLUSIONS: Relative to other cancer and orthopedic patients, the VTE rate is extremely high in patients with MBD. The discordant recommendations of thromboprophylaxis, and absence of research in this distinct and more granular surgical oncology subgroup, underpins the challenges associated with developing guidelines to lessen the VTE risks in the MBD patient population.

Identification of hypercoagulability with thrombelastography in patients with hip fracture receiving thromboprophylaxis.

Background: Venous thromboembolism (VTE) is the second most common complication after hip fracture surgery. We used thrombelastography (TEG), a whole-blood, point-of-care test that can provide an overview of the clotting process, to determine the duration of hypercoagulability after hip fracture surgery. Methods: In this prospective study, consecutive patients aged 51 years or more with hip fractures (trochanteric region or neck) amenable to surgical treatment who presented to the emergency department were eligible for enrolment. Thrombelastography, including calculation of the coagulation index (CI) (combination of 4 TEG parameters for an overall assessment of coagulation) was performed daily from admission until 5 days postoperatively, and at 2 and 6 weeks postoperatively. All patients received 28 days of thromboprophylaxis. We used single-sample t tests to compare mean maximal amplitude (MA) values (a measure of clot strength) to the hypercoagulable threshold of greater than 65 mm, a predictor of in-hospital VTE. Results: Of the 35 patients enrolled, 11 (31%) were hypercoagulable on admission based on an MA value greater than 65 mm, and 29 (83%) were hypercoagulable based on a CI value greater than 3.0; the corresponding values at 6 weeks were 23 (66%) and 34 (97%). All patients had an MA value greater than 65 mm at 2 weeks. Patients demonstrated normal coagulation on admission (mean MA value 62.2 mm [standard deviation (SD) 6.3 mm], p = 0.01) but became significantly hypercoagulable at 2 weeks (mean 71.6 mm [SD 2.6 mm], p < 0.001). There was a trend toward persistent hypercoagulability at 6 weeks (mean MA value 66.2 mm [SD 3.8 mm], p = 0.06). Conclusion: More than 50% of patients remained hypercoagulable 6 weeks after fracture despite thromboprophylaxis. Thrombelastography MA thresholds or a change in MA over time may help predict VTE risk; however, further study is needed.

Contexte: La thromboembolie veineuse (TEV) est la deuxième complication la plus courante après une chirurgie pour fracture de la hanche. Nous avons eu recours à la thromboélastographie, un test de sang total effectué au point d'intervention et donnant une idée du processus de coagulation, pour évaluer la durée de l'hypercoagulabilité à la suite d'une chirurgie pour fracture de la hanche. Méthodes: Cette étude prospective a été menée auprès de patients consécutifs admissibles de 51 ans et plus qui se sont présentés à l'urgence pour une fracture de la hanche (région trochantérienne ou col du fémur) pouvant faire l'objet d'un traitement chirurgical. Une thromboélastographie (TEG), qui comprenait le calcul de l'indice de coagulation (IC) [combinaison de 4 paramètres du TEG permettant une évaluation globale de la coagulation], a été réalisée chaque jour, de l'admission au cinquième jour postopératoire, de même qu'à 2 et à 6 semaines postopératoires. Tous les patients ont suivi une thromboprophylaxie de 28 jours. Nous avons réalisé des tests t pour échantillon unique afin de comparer l'amplitude maximale (AM) moyenne (une mesure de la résistance d'un caillot) au seuil d'hypercoagulabilité de plus de 65 mm, un prédicteur de TEV à l'hôpital. Résultats: Des 35 patients recrutés, 11 (31 %) présentaient une hypercoagulabilité à l'admission selon une AM supérieure à 65 mm, et 29 (83 %) présentaient une hypercoagulabilité selon un IC supérieur à 3,0; les valeurs correspondantes à 6 semaines étaient de 23 (66 %) et de 34 (97 %), respectivement. Tous les patients avaient une AM de plus de 65 mm à 2 semaines. Dans l'ensemble, les patients avaient une coagulation normale à l'admission (AM moyenne 62,2 mm [écart type (E.T.) 6,3 mm], p = 0,01), mais présentaient une hypercoagulabilité importante à 2 semaines (moyenne 71,6 mm [E.T. 2,6 mm], p < 0,001). L'hypercoagulabilité avait tendance à persister à 6 semaines (AM moyenne 66,2 mm [E.T. 3,8 mm], p = 0,06). Conclusion: Malgré la thromboprophylaxie, plus de 50 % des patients présentaient toujours une hypercoagulabilité 6 semaines après leur fracture. Les seuils d'AM à la thromboélastographie et les changements de l'AM au fil du temps pourraient aider à prédire le risque de TEV, mais d'autres études sur le sujet sont nécessaires.

Outcomes of mentoring programs in psychiatry training: a literature review.

OBJECTIVES: This literature review aimed to outline the evidence regarding the outcomes of formal mentoring programs for training psychiatrists. METHODS: An electronic search of Ovid MEDLINE, EMBASE, Ovid PsycINFO and The Cochrane Library was conducted. RESULTS: A total of 17 articles fulfilled inclusion criteria. Positive outcomes of mentorship include promotion of research, perpetuation of further mentorship, increased perceived support and enhancement of teaching skills. One article reported a negative outcome. CONCLUSIONS: Current evidence regarding mentorship in psychiatry is limited and there is a lack of clarity regarding the relationship between positive outcomes and mentorship. Components of the included programs may act as confounders. Mentorship, protected teaching time, and didactic teaching may be important to encourage research. Other potential benefits of mentorship include enhanced career guidance, perceived support, and enriched teaching skills.

Trends in implementation of evidence-based hip fracture management in a major Canadian city.

Aims: The importance of hip fracture care has resulted in an abundance of hip fracture management literature. The degree this evidence is incorporated into clinical practice is unknown. We examined 5 trends in hip fracture management: arthroplasty versus fixation, total hip arthroplasty (THA) versus hemiarthroplasty (HA), cemented versus uncemented femoral stem fixation, short versus long cephalomedullary nail (CMN) fixation, and time from admission to surgery. Our primary aim was to understand and assess hip fracture management trends in relation to pertinent literature. Methods: Data were collected from acute hip fractures in patients aged 50 years or older who presented from 2008 to 2018. ICD-10 diagnostic codes were assigned using preoperative radiographs. Surgical management was confirmed using intraoperative and postoperative radiographs and split into 6 categories: (1) short CMN, (2) long CMN, (3) cannulated screws, (4) dynamic hip screw, (5) HA, and (6) THA. Appropriate statistical tests were used to analyze trends. Results: In 4 assessed trends, hip fracture management aligned with high-level evidence. This was the case for a trend toward arthroplasty for displaced femoral neck fractures, increased use of THA relative to HA, increased use of short relative to long CMNs, and consistent decrease in surgical wait times. Despite the literature highlighting the disadvantages of uncemented femoral stems, our data demonstrated increased use of uncemented femoral stems. Conclusion: Evidence to guide orthopaedic practice is constantly emerging but may not be effectively used by clinicians. Our findings demonstrate the successes and failures of integrating evidence into hip fracture management and highlight that orthopaedic surgeons have an ongoing responsibility to strive for evidence-based practice.

An in vivo rabbit joint injury model to measure trauma-induced coagulopathy and the effect of timing of administration of ketotifen fumarate on posttraumatic joint contracture.

Objectives: Using a rabbit in vivo joint injury model, the primary objective of the study was to determine if a relationship exists between earlier time to initiation of ketotifen fumarate (KF) treatment and posttraumatic joint contracture (PTJC) reduction. The secondary objective was to determine if a coagulation response could be detected with serial thrombelastography (TEG) analysis following acute trauma in this model. Methods: PTJC of the knee were created in 25 skeletally mature, New Zealand White rabbits. Five groups of 5 animals were studied: a control group that received twice daily subcutaneous injections of normal saline and 4 treatment groups that received twice daily subcutaneous injections of KF (0.5 mg/kg) starting immediately, 1-, 2-, and 4-weeks post-injury. After 8 weeks of immobilization, flexion contractures were measured biomechanically. Serial TEG analysis was performed on the control group animals pre-injury and weekly post-injury. Results: The average joint contracture in the Control Group (43.1°â€Š±â€Š16.2°) was higher than all KF treatment groups; however, the differences were not statistically significant. The average joint contracture was lowest in the 2-week post-injury treatment group (29.4°â€Š±â€Š12.1°), although not statistically significant compared to the other treatment groups. Serial TEG analysis demonstrated significantly higher mean maximal amplitude (maximal amplitude = 68.9 ±â€Š1.7 mm; P < .001), alpha-angle (81.9°â€Š±â€Š0.9°; P < .001), and coagulation index (4.5 ±â€Š0.3; P < .001) 1-week post-injury, which normalized to pre-injury values by 5-weeks post-injury. Conclusions: The use of the mast cell stabilizer KF within 2 weeks of injury demonstrated a nonsignificant trend towards reducing joint contracture in a rabbit in vivo model of PTJC. TEG and the in vivo rabbit joint injury model may be valuable in future preclinical studies of venous thromboembolism prevention and furthering our understanding of the pathophysiology of posttraumatic hypercoagulability.

Comparison of Patient-Reported Outcomes After Suprapatellar Versus Infrapatellar Nailing Techniques for Tibial Shaft Fractures: A Systematic Review and Meta-analysis.

OBJECTIVES: To compare patient-reported outcome measures (PROMs) between patients who underwent intramedullary nail (IMN) fixation for tibial shaft fractures using an infrapatellar (IP) or the newer suprapatellar (SP) approach. Secondary outcomes included fluoroscopic radiation exposure, operative time, and radiographic outcomes. DATA SOURCES: A systematic literature search of the databases Ovid MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials Study Selection. STUDY SELECTION: Level I to III studies in which patients over the age of 18 years with acute tibial shaft fractures who underwent tibial IMN fixation using an IP or SP approach for fracture fixation were assessed for inclusion. Studies with a minimum of 10 patients in each cohort that reported on postoperative patient-reported outcomes with at least 6 months of follow-up were included for analysis. DATA EXTRACTION AND SYNTHESIS: Twelve studies that reported PROMs and compared IP and SP intramedullary nailing of tibial shaft fractures were analyzed. This included 654 patients who underwent IP IMN fixation and 542 patients who underwent SP IMN fixation. A random-effects model for unadjusted/crude study estimates were pooled using inverse variance (IV) weighting for continuous variable analysis. CONCLUSIONS: This review found a significant improvement in PROM for patients with tibial shaft fractures when the SP IMN technique was used. In addition, there was a significant decrease in intraoperative fluoroscopy time consistent with other radiographic findings demonstrating improved start point accuracy and reduction with SP IMN fixation of tibial shaft fractures. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Outcomes and complications after dual plate vs. single plate fixation of displaced mid-shaft clavicle fractures: A systematic review and meta-analysis.

INTRODUCTION: Open reduction and internal fixation (ORIF) of displaced midshaft clavicle fractures is associated with higher union rates and earlier functional recovery. However, ORIF with plate fixation is associated with complications including implant irritation and implant failure. Dual plate fixation provides fixation in orthogonal planes, and uses a lower profile fixation technique in comparison to pre-contoured and surgeon-contoured small-fragment locking plates, which may be more prominent. The objective of this study was to conduct a systematic review to summarize outcomes and complications associated with surgical fixation of displaced acute midshaft clavicle fractures with dual plate fixation. METHODS: Using a predetermined study protocol in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, the databases MEDLINE, EMBASE, and CENTRAL were searched from inception to 2020 to identify studies reporting outcomes in acute midshaft clavicle fractures treated with dual plate fixation. All clinical studies which reported on outcomes of dual plating in patients with acute midshaft clavicle fractures were included. Baseline demographics, plate fixation constructs, fracture union rates, implant removal rates, maintenance of reduction, symptomatic implant rates, wound complications, and functional outcomes were extracted. All extracted data were recorded, and descriptive statistics were summarized. Meta-analysis was performed on fracture union rates and implant removal rates using random-effects modeling using Mantel-Haenszel weighting. RESULTS: Our literature search identified 2226 unique abstracts, of which eight studies met our study inclusion criteria following review. A total of 278 patients made up of 79.8% male with an average age of 36.0 years were included. The overall dual plate implant removal rate was 4.2% with excellent rates of union reported. Moreover, single plate fixation was associated with a 3.9-fold increased implant removal rate compared to dual plate fixation. CONCLUSION: Results from this systematic review demonstrate that ORIF of displaced midshaft clavicle fractures using a dual plate fixation technique is a viable option to reduce the incidence of implant removal, without negatively impacting the rate of fracture union. LEVEL OF EVIDENCE: Therapeutic Level III.

Cost-effectiveness of dual-mobility components in patients with displaced femoral neck fractures.

AIMS: Total hip arthroplasty (THA) with dual-mobility components (DM-THA) has been shown to decrease the risk of dislocation in the setting of a displaced neck of femur fracture compared to conventional single-bearing THA (SB-THA). This study assesses if the clinical benefit of a reduced dislocation rate can justify the incremental cost increase of DM-THA compared to SB-THA. METHODS: Costs and benefits were established for patients aged 75 to 79 years over a five-year time period in the base case from the Canadian Health Payer's perspective. One-way and probabilistic sensitivity analysis assessed the robustness of the base case model conclusions. RESULTS: DM-THA was found to be cost-effective, with an estimated incremental cost-effectiveness ratio (ICER) of CAD $46,556 (£27,074) per quality-adjusted life year (QALY). Sensitivity analysis revealed DM-THA was not cost-effective across all age groups in the first two years. DM-THA becomes cost-effective for those aged under 80 years at time periods from five to 15 years, but was not cost-effective for those aged 80 years and over at any timepoint. To be cost-effective at ten years in the base case, DM-THA must reduce the risk of dislocation compared to SB-THA by at least 62%. Probabilistic sensitivity analysis showed DM-THA was 58% likely to be cost-effective in the base case. CONCLUSION: Treating patients with a displaced femoral neck fracture using DM-THA components may be cost-effective compared to SB-THA in patients aged under 80 years. However, future research will help determine if the modelled rates of adverse events hold true. Surgeons should continue to use clinical judgement and consider individual patients' physiological age and risk factors for dislocation. Cite this article: Bone Joint J 2021;103-B(12):1783-1790.

Effect of oral anticoagulant use on surgical delay and mortality in hip fracture.

AIMS: Current guidelines recommend surgery within 48 hours among patients presenting with hip fractures; however, optimal surgical timing for patients on oral anticoagulants (OACs) remains unclear. Individual studies are limited by small sample sizes and heterogeneous outcomes. The aim of this study was to conduct a systematic review and meta-analysis to summarize the effect of pre-injury OACs on time-to-surgery (TTS) and all-cause mortality among older adults with hip fracture treated surgically. METHODS: We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) from inception to 14 October 2019 to identify studies directly comparing outcomes among hip fracture patients receiving direct oral anticoagulants (DOACs) or vitamin K antagonists (VKAs) prior to hospital admission to hip fracture patients not on OACs. Random effects meta-analyses were used to pool all outcomes (TTS, in-hospital mortality, and 30-day mortality). RESULTS: A total of 34 studies (involving 39,446 patients) were included in our systematic review. TTS was 13.7 hours longer (95% confidence interval (CI) 9.8 to 17.5; p < 0.001) among hip fracture patients on OACs compared to those not on OACs. This translated to a three-fold higher odds of having surgery beyond the recommended 48 hours from admission (odds ratio (OR) 3.0 (95% CI 2.1 to 4.3); p = 0.001). In-hospital mortality was higher (OR 1.4 (95% CI 1.0 to 1.8); p < 0.03) among anticoagulated patients. Among studies comparing anticoagulants, there was no statistically significant difference in time-to-surgery between patients taking a DOAC compared to a VKA. CONCLUSION: Patients presenting with a hip fracture who were taking OACs prior to injury experience a delay in time-to-surgery and higher mortality than non-anticoagulated patients. Patients on DOACs may be at risk of further delays. Evaluating expedited surgical protocols in hip fracture patients on OACs is an urgent priority, with the potential to decrease morbidity and mortality in this group of high-risk patients.

Surgical timing for open fractures: Middle of the night or the light of day, which fractures, what time?

Controversy exists over the optimal management of open fractures as new clinical studies question open fracture management dogma. Open fractures are complex injuries requiring the orthopaedic surgeon to consider both the bone injury as well as associated soft tissue injury. Early intravenous antibiotics and tetanus prophylaxis remain instrumental in infection prevention. However, the "six-hour rule" for initial open fracture debridement and revascularization has come into question. New evidence supports initial debridement within 24 hours with the appropriate surgical team. Additionally, orthopaedic surgeons and vascular surgeons should collaborate on the sequence of management of open fractures with associated vascular injury. Whereas debates on the optimal irrigation pressure and solution have been answered by multicenter randomized controlled trials, further research is required to determine the optimal irrigation volume and timing of wound closure. With advances in management of open fractures, the utility of well-known classification systems including the Gustilo-Anderson classification and Mangled Extremity Severity Score need to be re-evaluated in favor of up-to-date classification systems which better guide management and predict prognosis.

Limiting Blood Loss in Orthopaedic Trauma: Strategies and Effects.

Trauma is a major cause of mortality globally, with post-traumatic hemorrhage being the leading cause of death amongst trauma patients. In this paper, the authors review the underlying pathophysiology of trauma-related hemorrhagic shock, specifically the factors which contribute to the development of the acute coagulopathy of trauma shock (ACoTS). We then review the best available evidence for treatment strategies in the pre-hospital setting, as well as the in-hospital setting. Interventions that are strongly supported in the literature include utilization of a well-organized trauma system with direct transport to a designated trauma centre, the early use of tranexamic acid, and damage control orthopaedic surgical techniques and resuscitation protocols. Targeted resuscitation is an evolving field, with use of thromboelastography to guide resuscitation being a particularly promising area. Special trauma populations at particularly high risk are also reviewed, including the geriatric population, as well as unstable pelvic fractures, which are each at increased risk for poor outcomes, and deserve special attention. Major advances have been made in this important area, and ongoing research into the understanding and correction of ACoTS will continue to guide practice.

Current Concepts in Rehabilitation Protocols to Optimize Patient Function Following Musculoskeletal Trauma.

Musculoskeletal (MSK) trauma is a major cause of disability and pain worldwide. Despite surgical advances following MSK injuries, poor functional outcomes following surgery remain a major public health concern. Traditional methods of rehabilitation involving bed rest and immobilization led to muscle weakness, joint stiffness, and an inability to return to previous levels of activity. Recent research has provided evidence that early rehabilitation with a multidisciplinary team can prevent these negative outcomes and improve functional outcomes following MSK trauma. In order to continue to optimize recovery, standardized rehabilitation protocols and technological advances are required.

Outcomes following pelvic ring fractures in the paediatric population: A systematic review.

BACKGROUND: Pelvic fractures represent a small proportion of all paediatric fractures, but are likely to be associated with a high-energy mechanism, multiple injuries, and significant morbidity and mortality. Operative fixation of unstable pelvic fractures is accepted. However, there remains a paucity of data on functional outcomes and complications following pelvic fractures in the skeletally immature. METHODS: A PRISMA-compliant systematic review was performed, searching Medline, Embase, and Cochrane central review. The primary outcome was functional outcome after pelvic fractures in the paediatric population following operative or non-operative treatment. Secondary outcomes included mechanism of injury, associated injuries, mortality rate, and method of surgical fixation if required. Where possible, weighted totals of the data set were performed. RESULTS: In total, 23 studies were included in this review. Only eight studies reported functional outcomes, with limb length discrepancy and limp being the most common complication. Only 8.8% of all pelvic fractures underwent surgical fixation. Motor vehicle collision was the most common cause of injury, and extremity fracture was the most common associated injury. CONCLUSION: Paediatric pelvic fractures are caused by high-energy mechanisms and have significant morbidity and mortality. There remains a paucity of information on functional outcomes after these injuries.

Acute Disseminated Intravascular Coagulation After Prophylactic Nailing of the Femur in a Patient with Metastatic Prostate Cancer: A Case Report.

CASE: We present a case of acute disseminated intravascular coagulation (DIC) after prophylactic femoral intramedullary stabilization in a patient with metastatic prostate cancer. Preoperative international normalized ratio of 1.4 was attributed to malnutrition, and the patient was not medically optimized. DIC developed 1 hour postoperatively and was managed with blood product resuscitation. At the 4-month follow-up, the patient presented with bilateral pulmonary emboli and was transitioned to palliative care. CONCLUSIONS: DIC after intramedullary stabilization in patients with metastatic bone disease is a rare condition with high mortality rate. Early recognition, blood product resuscitation, and involvement of appropriate subspecialty services are imperative in DIC management.
