Objective: The purpose of this study is to assess differences in language characteristics in personal statements written by male and female applicants to an orthopedic surgery residency program., Design: This is a blinded retrospective analysis of personal statements from all applicants to an orthopedic surgery residency training program during 1 application cycle. Language characteristics were analyzed using a linguistic analysis software. This software evaluated 19 variables, including word count, 4 summary language variables (analytical thinking, clout, authenticity, and emotional tone), and 14 additional word categories., Setting: Our study took place at [institution]., Participants: All applications submitted during the 2018-2019 residency application cycle were analyzed. 889 applicants were included in the study based on exclusion criteria, which omitted the 5 applicants who ultimately matched at our institution, as well as non-US citizens., Results: Word count was not statistically significant between groups. Amongst the summary language variables, authenticity was higher in female applicants (p = 0.0142). Of the selected word categories, males averaged a higher score in certainty (p = 0.0418), while females averaged higher scores in curiosity (p = 0.0102), perception (p = 0.0486), and attention (p = 0.0293)., Conclusions: Subtle differences exist in the language characteristics of personal statements written by male and female applicants to orthopedic surgery residency. The implications of our findings would be strengthened by new data on specific language characteristics and communication skills most desired by orthopedic program directors. Lastly, as evaluation metrics for residency applications continue to change, personal statements may assume an even more important role., (Copyright © 2024 Association of Program Directors in Surgery.

Osteochondral lesions of the talus are common injuries that are most often the result of trauma. The natural progression of osteochondral lesions is not well understood. It is still unclear which lesions eventually lead to joint degeneration and osteoarthritic changes and if the treatment method affects the progression. The existing literature surrounding this topic is sparse, with inconsistent findings. The presented images are taken from a 72-year-old man with bilateral osteochondral lesions of the talus. To our knowledge, this is the first published series of images illustrating the natural progression of a patient with bilateral osteochondral lesions of the talus over a 12-year time period.

Background:   To describe the surgical technique of non-compressive intramedullary threaded nail (IMTN) fixation of distal ulnar neck fractures and present the clinical and radiographic outcomes of four patients treated with this novel technique., Methods: At a single Level 1 Trauma Center, a retrospective review was conducted for patients with distal ulnar neck fractures treated with retrograde IMTN between 2022 and 2024. Exclusion criteria included inadequate follow-up. A single surgeon performed all procedures using percutaneous retrograde IMTN fixation through the central disc of the triangular fibrocartilage complex (TFCC). Patients initiated a range of motion (ROM) protocol two weeks post-operatively. Post-operative radiographic images were used to calculate the ratio of IMTN diameter to the distal ulnar medullary isthmus diameter proximal to the fracture site. Radiographic changes in displacement, angulation, and ulnar variance were calculated between the first and last follow-up radiographs. Functional outcomes including grip strength and ROM were collected., Results: Four patients with distal ulnar neck fractures were treated with retrograde IMTN between 2022 and 2024. They were followed for a minimum of three months post-operatively. All were female with an average age of 65 years. All distal ulna fractures were associated with operatively treated intraarticular distal radius fractures. All patients were treated with 75 mm length and 4.5 mm diameter IMTNs. IMTN-to-Isthmus ratio was greater than 60% in all cases. Average radiographic displacement and angulation were unchanged at the final follow-up. The average ulnar variance increased by 1.2 mm. At the final follow-up, there were no post-operative complications. No cases demonstrated ulnar-sided wrist pain, nonunion, or required revision surgery., Conclusions: Retrograde IMTN fixation is a novel surgical technique for the treatment of distal ulnar neck fractures. We found limited but promising post-operative radiographic and functional outcomes in our patients without reported ulnar-sided wrist pain, nonunion, or need for hardware removal., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Purpose: To describe the currently available literature reporting clinical outcomes for bioactive and bioinductive implants in sports medicine., Methods: In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic search of 4 databases was completed to identify eligible studies. Inclusion criteria were studies using bioactive or bioinductive implants in human clinical studies for sports medicine procedures. Data were extracted and reported in narrative form, along with study characteristics., Results: In total, 145 studies were included involving 6,043 patients. The majority of included studies were level IV evidence (65.5%), and only 36 included a control group (24.8%). Bioactive materials are defined as any materials that stimulate an advantageous response from the body upon implantation, whereas bioinductive materials provide a favorable environment for a biological response initiated by the host. Bioactivity can speed healing and improve clinical outcome by improving vascularization, osteointegration, osteoinduction, tendon healing, and soft-tissue regeneration or inducing immunosuppression or preventing infection. The most common implants reported were for knee (67.6%, primarily cartilage [most commonly osteochondral defects], anterior cruciate ligament, and meniscus), shoulder (16.6%, primarily rotator cuff), or ankle (11.7%, primarily Achilles repair). The most common type of implant was synthetic (44.1%), followed by autograft (30.3%), xenograft (16.6%), and allograft (9.0%). In total, 69% of implants were standalone treatments and 31% were augmentation., Conclusions: The existing bioactive and bioinductive implant literature in sports medicine is largely composed of small, low-level-of-evidence studies lacking a control group., Clinical Relevance: Before bioactive implants can be adapted as a new standard of care, larger, comparative clinical outcome studies with long-term follow-up are essential., Competing Interests: Disclosures The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: B.R.W. reports speaker fees and fellowship support from Arthrex; received fellowship support from Smith & Nephew; received consulting fees from DePuy Mitek/Johnson & Johnson; received stock options and served on the scientific advisory board for Vivorte, Kaliber AI, and Sparta Bioscience; received personal fees and served as associate editor for Arthroscopy; received consultant feed and served on the design team for FH Ortho; and personal fees and served on the scientific advisory board for Vericel, outside the submitted work.

Sport-related concussion prevention strategies in collision sports are a primary interest for sporting organizations and policy makers. After-market soft-shell padding purports to augment the protective capabilities of standard football helmets and to reduce head impact severity. We compared head impact kinematics [peak linear acceleration (PLA) and peak rotational acceleration (PRA)] in athletes wearing Guardian Cap soft-shell padding to teammates without soft-shell padding. Ten Division I college football players were enrolled [soft-shell padding (SHELL) included four defensive linemen and one tight end; non-soft-shell (CONTROL) included two offensive linemen, two defensive linemen, and one tight end]. Participants wore helmets equipped with the Head Impact Telemetry System to quantify PLA (g) and PRA (rad/s 2 ) during 14 practices. Two-way ANOVAs were conducted to compare log-transformed PLA and PRA between groups across helmet location and gameplay characteristics. In total, 968 video-confirmed head impacts between SHELL ( n = 421) and CONTROL ( n = 547) were analyzed. We observed a Group x Stance interaction for PRA (F 1,963 = 7.21; p = 0.007) indicating greater PRA by SHELL during 2-point stance and lower PRA during 3- or 4-point stances compared to CONTROL. There were no between-group main effects. Protective soft-shell padding did not reduce head impact kinematic outcomes among college football athletes.

Head impacts and physical exertion are ubiquitous in American football, but the relationship between these factors is poorly understood across a competitive season or even within an individual session. Gameplay characteristics, including player position and session type, may contribute to these relationships but have not been prospectively examined. The current study aimed to determine if an association exists between head impact biomechanics and physical load metrics. We prospectively studied college football players during the 2017-2021 football seasons across representative playing positions (15 offensive and defensive linemen, 11 linebackers and tight ends, and 15 defensive backs, running backs, and receivers). Participants wore halters embedded with Catapult Vector GPS monitoring systems to quantify player load and participant helmets were equipped with the Head Impact Telemetry System to quantify head impact biomechanics and repetitive head impact exposure (RHIE). Generalized linear models and linear regression models were employed to analyze in-session and season-long outcomes, while addressing factors such as player position and session type on our data. Player load was associated with RHIE (p < 0.001). Season-long player load predicted season-long RHIE (R 2  = 0.31; p < 0.001). Position group affected in-session player load (p = 0.025). Both player load and RHIE were greater in games than in practices (p < 0.001), and position group did not affect RHIE (p = 0.343). Physical load burden was associated with RHIE within sessions and across an entire season. Session type affected both RHIE and player load, while position group only affected player load. Our data point to tracking physical load burden as a potential proxy for monitoring anticipated RHIE during the season., (© 2022.
