Open Suprascapular Nerve Decompression at the Spinoglenoid Notch.

Suprascapular nerve (SSN) entrapment is a rare but significant cause of posterior shoulder pain and weakness. Compression of the nerve at the level of the spinoglenoid notch leads to weakness and atrophy of the infraspinatus. A detailed history and physical examination along with appropriate workup are paramount to arrive at this diagnosis.

Anatomic or reverse total shoulder arthroplasty? How fellowship training affects selection of arthroplasty type.

Background: Although both anatomic (ATSA) and reverse total shoulder arthroplasty (rTSA) have been popularized as a means of treating individuals with degenerative shoulder conditions, the indications for each can vary widely among providers. Although surgeons with differing fellowship training commonly perform these procedures, it is not understood how fellowship training influences choice of implant.

Methods: A national database was queried to identify surgeons performing ATSA and rTSA.

Preoperative factors predict prolonged length of stay, serious adverse complications, and readmission following operative intervention of proximal humerus fractures: a machine learning analysis of a national database.

Background: Proximal humerus fractures are a common injury, predominantly affecting older adults. This study aimed to develop risk-prediction models for prolonged length of hospital stay (LOS), serious adverse complications, and readmission within 30 days of surgically treated proximal humerus fractures using machine learning (ML) techniques.

Methods: Adult patients (age >18) who underwent open reduction internal fixation (ORIF), hemiarthroplasty, or total shoulder arthroplasty for proximal humerus fracture between 2016 and 2021 were included.

Publicly Available Anatomic Total Shoulder Arthroplasty Rehabilitation Protocols Show High Variability and Frequent Divergence from the 2020 ASSET Recommendations.

Background: In 2020, the American Society of Shoulder and Elbow Therapists (ASSET) published an evidence-based consensus statement outlining postoperative rehabilitation guidelines following anatomic total shoulder arthroplasty (TSA).

Purpose: The purpose of this study was to (1) quantify the variability in online anatomic TSA rehabilitation protocols, and (2) assess their congruence with the ASSET consensus guidelines.

Methods: This study was a cross-sectional investigation of publicly available, online rehabilitation protocols for anatomic TSA.

How fellowship training affects complication rate after shoulder arthroplasty: a nationwide assessment.

Background: Total shoulder arthroplasty is performed by orthopedic surgeons with various fellowship training backgrounds. Whether surgeons performing shoulder arthroplasty with different types of fellowship training have differing rates of complications and reoperation remains unknown.

Methods: The PearlDiver Mariner database was retrospectively queried from the years 2010 to 2022.

Clinical Outcomes and Survivorship of Lateral Unicompartmental Knee Arthroplasty: A Large Single Surgeon Cohort.

Background: Lateral unicompartmental knee arthroplasty (UKA) is an effective treatment for isolated lateral compartment osteoarthritis. However, due to the rarity of the procedure, long-term outcomes and survivorship are poorly understood. We report the clinical and radiographic outcomes after lateral UKA.

Analysis of patient-directed search content and online resource quality for ulnar collateral ligament injury and surgery.

Background: Patients use the Internet to learn information about injuries, yet online content remains largely unstudied. This study analyzed patient questions posed online regarding ulnar collateral ligament (UCL) tears or UCL surgical management.

Methods: Three separate search strings about UCL tear and UCL surgery were queried on the Google search engine.

Bisphosphonate Use May be Associated With an Increased Risk of Periprosthetic Hip Fracture.

Background: Osteoporosis is common among patients undergoing primary total hip arthroplasty (THA). This study aimed to evaluate the effect of bisphosphonate treatment on osteoporotic patients undergoing primary THA.

Methods: Using a national database, 30,137 patients who had osteoporosis before primary elective THA were identified during 2010 to 2020.

Low Risk of Acute Iatrogenic Periprosthetic Joint Infection After Prosthetic Joint Aspiration.

Background: Synovial fluid analysis is an essential tool in diagnosing periprosthetic joint infection (PJI) after total knee arthroplasty (TKA). However, concern exists that aspiration may introduce infection into a noninfected joint. Therefore, the purpose of this study was to evaluate the incidence of iatrogenic PJI following diagnostic knee aspiration done within 6 months of the primary TKA.

Double-Row Repair With Platelet-Rich Plasma Optimizes Retear Rates After Small to Medium Full-Thickness Rotator Cuff Repair: A Systematic Review and Network Meta-analysis of Randomized Controlled Trials.

Purpose: To compare the different interventions described in the literature for the surgical treatment of small and medium complete rotator cuff tears.

Methods: A systematic review of randomized controlled trials of small-medium, full-thickness rotator cuff tears published since 2000 was performed. Clinical characteristics, re-tear rates, range of motion (ROM), and patient-reported outcomes (PRO) data were collected.

Characterization of electric scooter injuries over 27 months at an urban level 1 trauma center.

Background: Electric scooters (e-scooters) have become a widespread method of transportation. The purpose of this study is to provide risk stratification tools for modifiable risk factors associated with e-scooter injury morbidity.

Methods: Patients at an urban Level 1 Trauma center sustaining e-scooter injuries between November 2017 through March 2020 were identified.

Does Youth Baseball Result in Morphologic Changes of the Lateral Elbow? A Prospective MRI Study.

Background: Stress from overhead throwing results in morphologic changes to the shoulder in youth baseball players. With greater valgus torque stresses, the elbow experiences injuries specifically attributed to throwing. However, no previous work that we know of has assessed throwing-related morphologic changes of the elbow without associated conditions.

Financial impact of electric scooters: a review of injuries over 27 months at an urban level 1 trauma center (cost of e-scooter injuries at an urban level 1 trauma center).

Background: Electric scooters (e-scooters) have become a widespread method of transportation due to convenience and affordability. However, the financial impact of medical care for sustained injuries is currently unknown. The purpose of this study is to characterize total billing charges associated with medical care of e-scooter injuries.

Electric Scooter Orthopaedic Injury Demographics at an Urban Level I Trauma Center.

Objectives: This study highlights demographics and orthopaedic injuries of electric scooter-related trauma that presented to our institution over a 27-month period.

Design: Retrospective review.

Setting: Urban Level 1 trauma center.

Longitudinally persistent cerebrospinal fluid B cells can resist treatment in multiple sclerosis.

B cells are key contributors to chronic autoimmune pathology in multiple sclerosis (MS). Clonally related B cells exist in the cerebrospinal fluid (CSF), meninges, and CNS parenchyma of MS patients. We sought to investigate the presence of clonally related B cells over time by performing Ig heavy chain variable region repertoire sequencing on B cells from longitudinally collected blood and CSF samples of MS patients (n = 10).
