Introduction Recent successes achieved with reverse shoulder arthroplasty (RSA) have led to an expansion of its indications and an increase in the number of commercially available designs in the global marketplace. Despite these development efforts, little guidance exists regarding reverse shoulder test methods and little published data exists regarding reverse shoulder performance standards. A...

Posterior dislocations of the shoulder joint can result in an impression fracture over the anteromedial humeral head, termed the reverse Hill-Sachs lesion, the presence of which can contribute to recurrent dislocations. Methods described to repair this defect include using allografts, iliac crest and coracoid process autografts, and bone graft substitutes. We describe a novel technique using th...

A 53-year-old woman presented with 10-year history of pain and limited range of motion in both shoulders. Radiographs of both shoulders showed severe shoulder osteoarthritis with glenoid bone defect. Very thin rotator cuff and superior migration of the humerus were also observed on computed tomography images. We performed bony increased-offset reverse total shoulder arthroplasty on her both sho...

HYPOTHESIS Shoulder arthroplasty is being performed with increasing frequency, and patients' athletic participation after shoulder arthroplasty is on the rise. However, little data exist regarding appropriate long-term activity restrictions. We hypothesize that European and North American surgeons both recommend increasing long-term activity restrictions, moving from hemiarthroplasty to total s...

BACKGROUND Different implant designs are utilized in reverse shoulder arthroplasty. The purpose of this systematic review was to evaluate the results of reverse shoulder arthroplasty using a traditional (Grammont) prosthesis and a lateralized prosthesis for the treatment of cuff tear arthropathy and massive irreparable rotator cuff tears. METHODS A systematic review of the literature was perf...

Purpose Purpose The purpose of this study was to determine patient-specific risk factors and clinical intervention rates for abnormal postoperative Chem-7 panels in shoulder arthroplasty patients. Methods Retrospectively, all primary anatomic total (aTSA) and reverse shoulder (RTSA) arthroplasties (between 2007-2013) performed at a single institution were identified. All patients underwent ro...

Background: Acromial stress fracture (ASF) is a unique complication of reverse shoulder arthroplasty (RSA) thatcan have substantial influence on clinical results. The purpose of this review is to describe demographics, functionaloutcomes, and union rates for cases of RSA complicated by ASF.Methods: A systematic review was conducted using Preferred Reporting Items for Systemati...

BACKGROUND AND PURPOSE Glenoid reconstruction and inverted glenoid re-implantation is strongly advocated in revisions of failed reverse shoulder arthroplasty (RSA). Nevertheless, severe glenoid deficiency may preclude glenoid reconstruction and may dictate less favorable solutions, such as conversion to hemiarthropasty or resection arthropasty. The CAD/CAM shoulder (Stanmore Implants, Elstree, ...
