The effect of radial mismatch on radiographic glenoid loosening.

Background: The ideal glenohumeral radial mismatch following anatomic total shoulder arthroplasty (TSA) remains ill defined, with biomechanical and clinical studies recommending a range between 4 and 10 mm. This study evaluates the effect of radial mismatch on the formation of radiolucent lines after TSA.

Methods: We evaluated 451 TSAs at a mean follow-up of 5.

Effect of Tuberosity Healing on Clinical Outcomes in Elderly Patients Treated With a Reverse Shoulder Arthroplasty for 3- and 4-Part Proximal Humerus Fractures.

Objectives: To evaluate tuberosity union rate and clinical outcome after 3- and 4-part proximal humerus fractures in the elderly.

Design: Retrospective, multicenter database cohort study.

Setting: Level I and Level II trauma centers.
