The Intrepid Dynamic Exoskeletal Orthosis (IDEO) brace is a custom energy-storing orthosis design meant to improve gait, stability, and function after lower extremity injury or limb salvage. Early studies demonstrated the potential for the IDEO to improve functional performance, in conjunction with its paired return to run (RTR) rehabilitation program, compared to other brace types, and an impressively decreased rate of late amputation. The current study aimed to investigate these functional and revision outcomes from our institution to determine which patients may benefit most from IDEO bracing and what factors of the IDEO design and rehabilitation program are most important for improved outcomes after lower extremity trauma and/or loss of function. ⋯ In select patients, the IDEO may decrease the desire for delayed amputation and permit higher levels of activity; however, its efficacy appears tied to the rehabilitative regimen, pain levels, and initial diagnosis. These findings should guide post-surgical extremity bracing prescriptions and expectations.

There is approximately a 2% risk of clinically significant VTE following temporary lower limb immobilisation after injury with an ankle immobilising plaster cast or boot. There is evidence that thromboprophylaxis for lower limb immobilised patients reduces the risk of VTE by approximately 50% but there is no international consensus as to which patients should receive thromboprophylaxis. The Plymouth VTE Risk Score was developed to identify patients at particular risk of VTE, in order to offer chemical prophylaxis to reduce their VTE risk. ⋯ This is a lower VTE incidence than in most other studies of this patient group, which is of the order of 2 to 3%. The optimal RAM to use in clinical practice is yet to be defined, further clinical research is needed to accurately stratify patient risk and to define optimal risk treatment levels. We suggest research should focus on comparative clinical studies of risk assessment models.

Review Meta Analysis
Reversal of direct oral anticoagulants in adult hip fracture patients. A systematic review and meta-analysis.
Increasing numbers of patients are taking Direct Oral Anticoagulants at the time of hip fracture. Evidence is limited on how and if the effects of DOAC's should be reversed before surgical fixation. Wide variations in practice exist. We conducted a systematic review to investigate outcomes for three reversal strategies. These were: "watch and wait" (also referred to as "time-reversal"), plasma product reversal and reversal with specific antidotes. ⋯ We suggested against "watch and wait" to reverse the DOAC effect in hip fractures. Further work is required to assess the optimal timing for surgery as well as the use of plasma products or specific antidotes in DOAC-taking hip fracture patients.

Although nonunions are among the most common complications after long-bone fracture fixation, the definition of fracture nonunion remains controversial and varies widely. The aim of this study was to identify the definitions and diagnostic criteria used in the scientific literature to describe nonunions after long-bone fractures. ⋯ In the current orthopaedic literature, we found a lack of consensus with regard to the definition of long-bone nonunions. Without valid and reliable definition criteria for nonunion, standardization of diagnostic and treatment algorithms as well as the comparison of clinical studies remains problematic. The lack of a clear definition emphasizes the need for a consensus-based approach to the diagnosis of fracture nonunion centred on clinical, radiographical and time-related criteria.

Randomized Controlled Trial
Evaluating the effectiveness of the Imperial Femoral Intramedullary Nailing Cognitive Task Analysis (IFINCTA) tool in a real-time simulation setting (Distributed Interactive Simulation): a randomized controlled trial.
Working time regulations, senior led service delivery and increasing complexity of surgical technology has led to significant strains in surgical training. Additionally, the current COVID-19 pandemic has placed substantial limitations on surgical training worldwide. Contact free, remote, web-based, validated learning tools which are easily accessible and allows repeated, sustained practice are the need of the hour. Cognitive Task Analysis (CTA) have been used extensively to train pilots and military personnel and has shown excellent early results within orthopaedic training. We designed a femoral nailing CTA tool which showed objective benefits in the enhancement of cognitive knowledge in medical students. The aim of this study was to evaluate the effectiveness of this CTA tool to enhance practical skills in orthopaedic trainees in a real time interactive simulation setting (Distributed Interactive Simulation (DIS)). ⋯ This study has demonstrated objective benefits of a novel femoral nailing CTA tool in the enhancement of practical skills for junior trainees in the DIS setting. This adds to the growing evidence supporting the use of CTA in orthopaedic training. This tool can be accessed remotely, is contact free and allows repeated sustained practice which is key in simulation training.
