Background: Return to sport (RTS) commonly serves as a measure for assessment of clinical outcomes in orthopaedic sports medicine surgery. Unfortunately, while RTS is commonly utilized in research for this purpose, currently there is no widely accepted or standardized definition for when an athlete has officially returned to his or her sport. Purpose: To conduct a systematic review to evaluate and report the differences in specific definitions of RTS utilized in the orthopaedic surgery literature. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed using PubMed, EMBASE, and Cochrane Trials databases per PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Search terms consisted of variations of “RTS” combined with variations of “orthopedic surgery” and “define” to capture as many relevant articles as possible. The definition of RTS was recorded and analyzed. Results: A total of 718 articles were identified in the initial search, 29 of which met eligibility criteria, providing a clear definition of RTS. Of the 29 studies included, 20 (69.0%) defined RTS as an athlete competing in a game or other competitive play. Three (10.3%) defined this as the athlete competing in a game or other competitive play but with an explicitly stated competition-level modifier of the athlete returning to his or her preinjury level of competition. Two articles (6.9%) included returning to training or practice, and the remaining 4 articles (13.8%) used terminology other than the standard RTS. Conclusion: There is variability in the definition of RTS used in orthopaedic sports medicine literature. Most studies refer to the athlete competing in a game or other competitive play. Other variants include returning to practice/training and explicitly defined competition levels and objectives. Future studies should aim to standardize the definition of RTS to facilitate more precise assessment of outcome after sports medicine surgery. Using terminology that describes components of the recovery and rehabilitation process, such as “return to participation” and “return to performance,” in addition to RTS will allow us to more clearly understand the athlete’s recovery and associated level of competition or performance.
Background: The common peroneal nerve (CPN) is the most commonly injured peripheral nerve of the lower extremity in patients with trauma. Traumatic CPN injuries have historically been associated with relatively poor outcomes and patient satisfaction, although improved surgical technique and novel procedures appear to improve outcomes. Given the variety of underlying injury modalities, treatment options, and prognostic variables, we sought to evaluate and summarize the current literature on traumatic CPN injuries and to provide recommendations from an analysis of the included studies for treatment and future research.Methods: A systematic review was performed using PubMed, Embase, and Cochrane databases per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Search terms consisted of variations of "peroneal nerve" or "fibular nerve" combined with "injury," "laceration," "entrapment," "repair," or "neurolysis." Information with regard to treatment modality, outcomes, and patient demographic characteristics was recorded and analyzed. Results:The initial search yielded 2,301 articles; 42 met eligibility criteria. Factors associated with better outcomes included a shorter preoperative interval, shorter graft length when an interposed graft was used, nerve continuity, and younger patient age. Gender or sex was not mentioned as a factor affecting outcomes in any study. Motor grades of $M3 on the British Medical Research Council (MRC) scale are typically considered successful outcomes. This was achieved in 81.4% of patients who underwent neurolysis, 78.8% of patients who underwent end-to-end suturing, 49.0% of patients who underwent nerve grafting, 62.9% of patients who underwent nerve transfer, 81.5% of patients who underwent isolated posterior tibial tendon transfer (PTTT), and 84.2% of patients who underwent a surgical procedure with concurrent PTTT.Conclusions: Studies included in this review were heterogenous, complicating our ability to perform further analysis. It is not possible to uniformly advocate for the best treatment option, given diverse injury modalities and patient presentations and a variety of prognostic factors. Many studies do not show outcomes with respect to injury modality. Future studies should show preoperative muscle strengths and should clearly define outcomes based on the injury modality and surgical treatment option. This would allow for greater analysis of the most appropriate treatment option for a given mechanism of injury. Newer surgical techniques are promising and should be further explored.
Personal protective equipment (PPE) shortages represent a persistent and critical challenge during the COVID-19 pandemic. Communities of 3D printing hobbyists and experts responded by designing and producing homemade, 3D-printed PPE. This report discusses the design, manufacturing and validation of the Kansas City Mask (KC Mask). Once printed and assembled, masks were fit tested at Truman Medical Center in Kansas City, MO. The KC Mask was approved for use by pandemic response administration staff at the hospital. Fortunately, due to adequate PPE supply at the time of this publication, wide utilization of the KC mask has not been required. The authors endorse the KC Mask as a stopgap measure, proven to be effective in situations of critical PPE shortage based on Centers for Disease Control and Prevention (CDC) guidelines.
Purpose Controversy exists regarding the acute effect of non-steroidal anti-inflammatory drugs (NSAIDs) on early fracture healing. The purpose of this study was to analyze the rate of nonunion or delayed union in patients with fifth metatarsal (5th MT) fractures. We hypothesize that the use of NSAIDs would increase the rate of nonunion/delayed union in 5th MT fractures. Methods Using PearlDiver, a national insurance database was analyzed. ICD codes were used to identify patients diagnosed with 5th MT fracture from 2007-2018. Patients were grouped by initial management (nonoperative vs. open reduction and internal fixation (ORIF) or non/malunion repair within 60 days) and sub-grouped by whether they had been prescribed at least one pre-defined NSAID. Subsequent ORIF or nonunion/malunion repair operative intervention was used as a surrogate for fracture nonunion/delayed union. Results Of the 10,991 subjects with a diagnosis of 5th MT, 10,626 (96.7%) underwent initial nonoperative treatment, 1,409 of which (13.3%) received prescription NSAIDS within 60 days of diagnosis. 16/1,409 (1.14%) subjects who received anti-inflammatory prescriptions underwent ORIF or repair of non/malunion at least 60 days after diagnosis while 46/9,217 (0.50%; P=0.003483) subjects who did not receive anti-inflammatory prescriptions underwent ORIF or repair of non/malunion at least 60 days after diagnosis. In the 365 subjects who underwent early repair/ORIF (within 60 days), there was no significant difference in the rate of nonunion/delayed union. Conclusion The rate of nonunion/delayed union of 5th MT fractures was significantly higher in subjects receiving NSAIDs within 60 days of initial diagnosis in patients managed non-operatively. Level of evidence Level III
Personal protective equipment (PPE) shortages persist amidst increasing COVID-19 caseloads. These shortages encouraged some to pursue 3D printing to produce stopgap N95 alternatives. The design presented is an adapter for a commercially available snorkel mask to serve as a full-face respirator, used in dire PPE shortages or in individuals who failed fit testing. Masks were fit tested at The University of Kansas Health System in Kansas City, KS. The mask was fit tested on 22 individuals who previously failed fit testing, and all passed qualitative fit testing with the snorkel mask, adapter and viral filter apparatus. The authors endorse this design as a stopgap measure, proven to be effective in situations of dire PPE shortage or for individuals who have failed fit testing with conventional PPE.
