Inferior tilt of the glenoid component does not decrease scapular notching in reverse shoulder arthroplasty: results of a prospective randomized study.

Hypothesis: The purpose of this study was to determine if inferior tilt of the glenoid component decreased the amount of radiographic scapular notching after reverse shoulder arthroplasty. A secondary goal was to determine if inferior tilt had any effect on clinical outcome.

Materials And Methods: A prospective randomized trial of 52 consecutive reverse shoulder arthroplasties performed by 1 surgeon for cuff tear arthropathy was performed.

Utility of polymer cerclage cables in revision shoulder arthroplasty.

Revision shoulder arthroplasty often requires humeral osteotomy for stem extraction or is complicated by periprosthetic fracture. In these situations, various modes of fixation are used, including cerclage wires, cable plates, and allograft strut augmentation. The use of metal wires and cables, however, has been associated with soft tissue irritation, sharps injuries, and accelerated wear of joint arthroplasty bearing surfaces.

What are the instability and infection rates after reverse shoulder arthroplasty?

Background: A concern regarding reverse shoulder arthroplasty (RSA) is the possibly higher complication rate compared with conventional unconstrained shoulder arthroplasty.

Questions/purposes: We determined (1) the rate of instability and infection; (2) whether diagnosis influenced instability and infection rates; and (3) whether these complications affect ASES, Constant, and WOOS scores after RSA.

Methods: A prospective database, clinical charts, and radiographs of 284 patients who had undergone primary (n = 212 patients) or revision (n = 72 patients) RSA were reviewed to identify patients whose postoperative course was complicated by instability or infection.
