Outcomes of revision versus re-revision reverse total shoulder arthroplasty: A case-control-matched cohort study.

Background: The increasing incidence of reverse total shoulder arthroplasties (RTSA) has led to an increase in revision surgery. We aimed to compare patients undergoing re-revision RTSA to a matched cohort undergoing first-revision RTSA.

Methods: A retrospective review of all revision RTSAs was performed at a single institution.

Survivorship analysis of revision reverse total shoulder arthroplasty.

Background: The expansion of indications for reverse total shoulder arthroplasty (RTSA) has resulted in a rapid increase in the incidence of subsequent revision procedures. The purpose of this study was to identify the incidence and risk factors for re-revision shoulder arthroplasty after first revision RTSA.

Methods: We retrospectively queried our institutional shoulder arthroplasty database of prospectively collected data from 2003 to 2019.

Testosterone Plus Finasteride Prevents Bone Loss without Prostate Growth in a Rodent Spinal Cord Injury Model.

We have reported that testosterone-enanthate (TE) prevents the musculoskeletal decline occurring acutely after spinal cord injury (SCI), but results in a near doubling of prostate mass. Our purpose was to test the hypothesis that administration of TE plus finasteride (FIN; type II 5α-reductase inhibitor) would prevent the chronic musculoskeletal deficits in our rodent severe contusion SCI model, without inducing prostate enlargement. Forty-three 16-week-old male Sprague-Dawley rats received: 1) SHAM surgery (T laminectomy); 2) severe (250 kdyne) contusion SCI; 3) SCI+TE (7.

Assessing the Quality of Mobile Exercise Apps Based on the American College of Sports Medicine Guidelines: A Reliable and Valid Scoring Instrument.

Background: Regular physical activity can not only help with weight management, but also lower cardiovascular risks, cancer rates, and chronic disease burden. Yet, only approximately 20% of Americans currently meet the physical activity guidelines recommended by the US Department of Health and Human Services. With the rapid development of mobile technologies, mobile apps have the potential to improve participation rates in exercise programs, particularly if they are evidence-based and are of sufficient content quality.

Pediatric Injuries at an Annual Motocross Competition: Rates and Severity.

Purpose: Pediatric motocross injuries occur frequently and with significant associated morbidity; however, data are limited regarding injury occurring during competition. North Central Florida hosts an annual motocross competition with numerous pediatric competitors. We sought to evaluate the rate and severity of injuries sustained at this event over a multiyear period.
