HYPOTHESIS Dislocation is the most common serious complication after reverse shoulder arthroplasty. One theorized cause is subscapularis insufficiency because the tendon cannot be repaired at the time of surgery. There are no documented risk assessments of reverse total shoulder arthroplasty dislocation related to this cause. The study objective was to quantify the risk of postoperative disloca...

Advanced glenohumeral osteoarthritis can transform glenoid morphology and, in some cases, is found in association with severe glenoid retroversion. The associated glenoid retroversion leads to difficulty in fixation of the glenoid component in reverse total shoulder arthroplasty. In the context of extreme glenoid wear, structural grafts can be used to restore glenoid volume and version in order...

BACKGROUND The younger patient with glenohumeral arthritis presents a challenge because of concerns about activity and frequency of failure. The purpose of this study was to define the results, complications, and frequency of revision surgery in this group. MATERIALS AND METHODS Between 1986 and 2005, 46 total shoulder arthroplasties and 20 hemiarthroplasties were performed in 63 patients who...

OBJECTIVES To obtain outcomes data on anatomical and reverse total shoulder arthroplasty by analysis of clinical scores and standard radiographs. SUBJECT SELECTION AND ENROLLMENT 400 consecutive series of patients replaced with anatomical and reverse total shoulder arthroplasty (minimum 3 years follow-up). STUDY DESIGN retrospective monocenter. PREOPERATIVE ASSESSMENT Demographics, clinic...

Shoulder arthroplasty represents one of the fastest growing orthopaedic procedures in the USA. In comparison to hemiarthroplasty, total shoulder arthroplasty has higher patient satisfaction and lower revision rates. Aseptic glenoid loosening remains a concern for longevity of total shoulder arthroplasties. Cement fixation on the glenoid side represents the primary and only mode of fixation in t...

The authors describe a step-by-step technique for reverse total shoulder arthroplasty using arthrotomy via the enlarged transacromial superior approach. This technique seems ideal for reinsertion of the tuberosities and to ensure adequate postoperative tensional balance of the infraspinatus and the subscapularis, which is critical for the rotator cuffs to function properly and to achieve optima...
