Lower socioeconomic status is correlated with worse outcomes after arthroscopic rotator cuff repair.

Background: Socioeconomic status has been recognized as a crucial social determinant of health influencing patient outcomes. Area Deprivation Index (ADI) is a validated measure of an area's socioeconomic status. Limited data exists on the impact of ADI and clinical outcomes and complications following rotator cuff repair (RCR).

Increased complications and similar patient recorded outcomes after shoulder arthroplasty in patients with functional somatic syndromes.

Background: The purpose of this study was to compare patient-reported outcomes measures, complication rates, and return to hospital in a cohort of patients undergoing anatomic total shoulder arthroplasty (aTSA) or reverse total shoulder arthroplasty (rTSA) with at least one functional somatic syndrome (FSS) to a control cohort.

Methods: A retrospective review identifying patients who underwent rTSA or aTSA from 2015 to 2022 was performed. Patients with one or more FSS diagnosis (irritable bowel syndrome, chronic headache, chronic low back pain, or fibromyalgia) were compared against a control cohort.

Utility of Artificial Intelligence in Orthopedic Surgery Literature Review: A Comparative Pilot Study.

Objective: Literature reviews are essential to the scientific process and allow clinician researchers to advance general knowledge. The purpose of this study was to evaluate if the artificial intelligence (AI) programs ChatGPT and Perplexity.AI can perform an orthopedic surgery literature review.

Augmented Total Elbow Arthroplasty with Femoral Strut Allograft for Revision of Prosthetic Joint Infection with Distal Humerus Bone Loss and Incomplete Union of Periprosthetic Humeral Shaft Fracture.

Total elbow arthroplasty (TEA) prosthetic joint infection (PJI) in the setting of distal humerus bone loss poses a challenge for restoration of function. This can be complicated by a periprosthetic humeral fracture. Revision surgery in the setting of these pathologies possesses a significant challenge, especially when two or, in this case, all three problems are treated simultaneously.

Lateralization in reverse shoulder arthroplasty: A review.

Reverse shoulder arthroplasty, as originally designed by Grammont, has revolutionized the treatment of rotator cuff arthropathy as well as fractures about the proximal humerus. The original design consisted of glenoid and humeral components with a medialized center or rotation compared to the native shoulder. Long term outcome studies on this design demonstrated high rates of scapular notching as well as significant loss of external rotation.

Multiple Cultures and Extended Incubation for Upper Extremity Revision Arthroplasty Affect Clinical Care: A Cohort Study.

Unlabelled: Skin flora organisms (SFOs) isolated from 1 to 2 tissue samples during shoulder and elbow revision arthroplasty are difficult to distinguish as contamination or infection. We examined the change in clinical care after implementation of an Arthroplasty Infection Protocol by increasing the number of intraoperative samples held for 10-day incubation to a minimum of 5.

Methods: Infection was defined as ≥3 cultures growing the same SFO or any one culture growing any other virulent organism.

Imaging of the B2 Glenoid: An Assessment of Glenoid Wear.

Background: Glenohumeral osteoarthritis (OA) carries a spectrum of morphology and wear patterns of the glenoid surface exemplified by complex patterns such as glenoid biconcavity and acquired retroversion seen in the B2 glenoid. Multiple imaging methods are available for evaluation of the complex glenoid structure seen in B2 glenoids. The purpose of this article is to review imaging assessment of the type B2 glenoid.

Comparison of radiographic and clinical outcomes of revision reverse total shoulder arthroplasty with structural versus nonstructural bone graft.

Background: Revision shoulder arthroplasty in the setting of glenoid bone loss poses substantial surgical challenges. This study's purpose was to compare radiographic and clinical results of patients requiring structural iliac crest bone autograft (ICBA) for severe bone loss versus patients with less severe bone loss treated with nonstructural bone allograft (NSBA) in the setting of revision reverse total shoulder arthroplasty (RSA).

Methods: A retrospective cohort of 30 patients (70% of the 43 patients who met the inclusion criteria) undergoing revision RSA with ICBA (n = 15) or NSBA (n = 15) between 2007 and 2015 were analyzed at a minimum 2-year follow-up.

Hemolytic strains of Propionibacterium acnes do not demonstrate greater pathogenicity in periprosthetic shoulder infections.

Background: Hemolysis has been suggested as a feature conferring increased pathogenicity to certain Propionibacterium acnes strains in the setting of shoulder infection. The purpose of this study was to compare the virulence of hemolytic and nonhemolytic P acnes strains in patients undergoing revision shoulder arthroplasty.

Methods: Thirty-nine patients with at least 1 positive culture growth for P acnes at the time of revision surgery were identified with P acnes isolates available for hemolysis testing.

Drill Penetration Injury to Extensor Tendons: A Biomechanical Analysis.

Background: Little is known about extensor tendon failure following drill injury at the time of volar plate fixation. Our goals were to analyze extensor tendon injury following simulated drill penetration, and change in tendon displacement during cyclic loading following simulated drill penetration injury.

Methods: Extensor pollicis longus (EPL) and extensor carpi radialis brevis (ECRB) tendons were harvested from 9 fresh frozen cadaveric arms.
