Randomized control trial of unconditional versus conditional incentives to increase study enrollment rates in participants at increased risk of lung cancer.

Introduction: Understanding how incentives and their timing influence study enrollment rates is important to efficient study design and increasing the generalizability of findings. This 2-arm, parallel randomized trial evaluated how conditional vs. unconditional mailed incentives of a $20 gift card affected study enrollment in a sample of participants screened for lung cancer screening.

Reverse shoulder arthroplasty used for revision of reverse shoulder arthroplasty: a systematic review.

Background: As reverse shoulder arthroplasty (RSA) cases increase, so too will the need to revise subsequent failures. Many of the complications associated with revising anatomic total shoulder and hemiarthroplasty have been adequately addressed by RSA including glenoid bone deficiency, instability, and functional outcomes. However, the risk for complication when revising a failed reverse prosthesis may be more pronounced with increased bone and soft tissue deficiency.

Glenohumeral osteoarthritis with intact rotator cuff treated with reverse shoulder arthroplasty: a systematic review.

Background: Although reverse shoulder arthroplasty (RSA) has shown satisfactory outcomes in rotator cuff-deficient shoulders, its performance in shoulders with an intact rotator cuff has not been fully elucidated. Shoulder osteoarthritis can present with alterations in glenoid morphology, which have contributed to inconsistent outcomes in anatomic shoulder replacement. The glenoid component is responsible for a predominance of these arthroplasty complications.

A Systematic Review of Radiolunate and Radioscapholunate Arthrodesis.

Purpose: The aims of this systematic review were to examine the use of radiolunate (RL) or radioscapholunate (RSL) arthrodesis as surgical management for patients with advanced radiocarpal arthritis that failed conservative management and to assess postoperative outcomes.

Methods: We reviewed articles from PubMed, EMBASE, and Web of Science from inception through December 2019. We identified complete manuscripts written in English reporting on RL or RSL arthrodesis for treatment of wrist pathology that included the primary outcomes (pain or grip strength) and at least 2 secondary outcomes (range of motion, patient-reported outcomes, or nonunion).
