Revision total elbow arthroplasty is associated with a high rate of 30-day complications: A descriptive analysis of a national database.

Introduction: Revision total elbow arthroplasty (TEA) is indicated for component loosening, periprosthetic joint infection, and fractures. Previous investigations into revision TEA complications have small sample sizes and limited exploration of acute complications. This study aims to characterize the 30-day complications and associated demographics of patients undergoing revision TEA using a large national database.

Surfer's neurapraxia - an uncommon surfing injury of the saphenous nerve.

Surfer's neurapraxia is a rare surfing injury of the saphenous nerve secondary to persistent compression of the saphenous nerve along the medial thigh by the surfboard when paddling prone and while sitting upright on the board waiting for a wave. Symptoms may be nonspecific and consist of pain in the medial thigh with or without radiation along the saphenous nerve distribution (medial leg, medial ankle, medial arch of the foot). The saphenous nerve tension test can be utilized to reproduce the symptoms of surfer's neurapraxia.

Python tooth-inspired fixation device for enhanced rotator cuff repair.

Rotator cuff repair surgeries fail frequently, with 20 to 94% of the 600,000 repairs performed annually in the United States resulting in retearing of the rotator cuff. The most common cause of failure is sutures tearing through tendons at grasping points. To address this issue, we drew inspiration from the specialized teeth of snakes of the Pythonoidea superfamily, which grasp soft tissues without tearing.

2-Octyl-Cyanoacrylate Mesh Dressings for Total Joint Arthroplasty: Dressing Design Influences Risks of Wound Complications.

Background: Recent liquid adhesive skin closure systems with a mesh patch and a 2-octyl cyanoacrylate liquid formula have shown promising results in total joint arthroplasty. Chemical accelerators are typically included to promote the rapid polymerization of 2-octyl cyanoacrylate. The goal of the study is to distinguish designs and wound complication differences between 2 similar systems.

"Trend" Statement Use in the Orthopaedic Literature.

Introduction: For research to effectively guide clinical decision making, appropriate interpretation of data is paramount. The P -value is a useful tool for guiding the interpretation of data. However, despite its utility, the P -value is not without limitations.

Graft Resorption After Posterior Distal Tibial Allograft Augmentation for Posterior Shoulder Instability: A Case Report.

Case: A 19-year-old man underwent arthroscopic posterior glenoid reconstruction with a distal tibia allograft (DTA) after failing 2 posterior, soft-tissue instability surgeries. Although he experienced near-complete resolution of symptoms and return to sport, graft resorption was noted 7 months postoperatively. The patient underwent revision surgery for screw removal.

Preoperative planning with three-dimensional CT vs. three-dimensional magnetic resonance imaging does not change surgical management for shoulder instability.

Background: This study aims to determine the effect of time and imaging modality (three-dimensional (3D) CT vs. 3D magnetic resonance imaging (MRI)) on the surgical procedure indicated for shoulder instability. The hypothesis is there will be no clinical difference in procedure selection between time and imaging modality.

Job satisfaction and practice characteristics of shoulder and elbow surgeons: a survey of American Shoulder and Elbow Surgeons society members.

Background: The purpose of this study is to assess the current trends in fellowship training, career satisfaction, practice characteristics, and surgical case volume among shoulder and elbow surgeons.

Methods: A web-based, anonymous 25-item survey was sent to the membership of the American Shoulder and Elbow Surgeons (ASES) in October of 2022. Questions posed included respondent demographics, fellowship training, career satisfaction, practice characteristics, and surgical case characteristics.

Post-operative Baseplate Radiographic Evaluation Using Routine pre-Operative CT.

Background: There is limited data evaluating post-operative component position and fixation in reverse shoulder arthroplasty (RSA). Therefore, the purpose of this study was to evaluate baseplate position and fixation using routine pre-operative CT and post-operative radiographs.

Methods: A retrospective analysis of a series consecutive patient who underwent primary RSA was performed.

The impact of implicit narrator reliability on production of information.

Previous research established that readers acquire accurate and inaccurate information from fiction. The current study explored factors that might moderate these effects. Participants read fictional stories that each contained three assertions.

Clavicle Nonunion and Malunion: Surgical Interventions for Functional Improvement.

Clavicle nonunion and malunion are relatively uncommon but, when symptomatic, can result in pain and dysfunction that requires surgical intervention. Various reconstructive and grafting techniques are available to achieve stable fixation and union. In the setting of persistent nonunion, vascularized bone grafting may be necessary.

The Fragility of Statistical Significance in Sham Orthopaedic Surgery: A Systematic Review of Randomized Controlled Trials.

Objectives: The purpose of this study was to determine the stability of statistical findings among sham surgery randomized controlled trials (RCTs) in orthopaedic surgery using fragility analysis.

Methods: PubMed systematic review was conducted to include studies reporting dichotomous outcomes pertaining to sham surgery. The final review included eight RCTs involving only partial meniscectomies and vertebroplasties from 2009 to 2020.

Artificial intelligence-based applications in shoulder surgery leaves much to be desired: a systematic review.

Background: Artificial intelligence (AI) aims to simulate human intelligence using automated computer algorithms. There has been a rapid increase in research applying AI to various subspecialties of orthopedic surgery, including shoulder surgery. The purpose of this review is to assess the scope and validity of current clinical AI applications in shoulder surgery literature.

The subacromial bursa is a key regulator of the rotator cuff and a new therapeutic target for improving repair.

Unlabelled: Rotator cuff injuries result in over 500,000 surgeries performed annually, an alarmingly high number of which fail. These procedures typically involve repair of the injured tendon and removal of the subacromial bursa. However, recent identification of a resident population of mesenchymal stem cells and inflammatory responsiveness of the bursa to tendinopathy indicate an unexplored biological role of the bursa in the context of rotator cuff disease.

Comparing Skill Acquisition and Validity of Immersive Virtual Reality with Cadaver Laboratory Sessions in Training for Reverse Total Shoulder Arthroplasty.

Unlabelled: Immersive virtual reality (iVR) allows surgical trainees to practice skills without risking harm to patients or the need for cadaveric training resources. However, iVR has never been directly compared with cadaver training, the longtime gold standard for surgical skill training. We aimed to compare skill acquisition using cadaver laboratory and iVR training methods for augmented baseplate implantation during reverse total shoulder arthroplasty (rTSA).

Quantifying the Opportunity Cost of Resident Involvement in Academic Orthopedic Shoulder Arthroplasty: A Matched - Pair Analysis.

Background: There is minimal work defining the economic impact of resident participation in shoulder arthroplasty. Thus, this study quantified the opportunity cost of resident participation in total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) by determining differences in operative time, relative value units (RVUs)/hour, and RVUs/case.

Methods: A retrospective analysis of shoulder arthroplasty procedures were identified from the ACS-NSQIP database from 2006 to 2014 using CPT codes.

Orthopaedic Surgery Residency: Perspective of Applicants and Program Directors on Medical Student Virtual Experiences.

Introduction: Orthopaedic Residency Directors advised against visiting subinternship rotations in the peak of the pandemic. To adapt, programs offered multiple virtual experiences. The purpose of this study was to evaluate programs and applicants perceptions regarding the value of virtual experiences during the 2020 to 2021 application cycle and their utility in future application cycles.
