A cadaver model was used to test the hypothesis that glenohumeral joint stability is independent of articular surface conformity after total shoulder arthroplasty. For the purposes of this study joint stability was defined as the minimum force required for joint dislocation. After arthroplasty components were implanted into fresh-frozen glenohumeral joints, specimens were mounted on a load fram...

This edition includes ten new chapters – total elbow arthroplasty, revised shoulder arthroplasty, proximal humerus hemiarthroplasty, extra articular proximal tibial fractures, submuscularis locked plating, subtrochanteric femur fractures, ankle fractures, calcaneal fractures, tibial pilon fractures, and staged ORIF. Seventeen chapters have been rewritten by new contributing authors and leaders ...

BACKGROUND Early designs of reverse shoulder arthroplasty components for the treatment of glenohumeral arthritis associated with severe rotator cuff deficiency in some cases have been associated with mechanical failure. The purpose of this study was to perform a prospective outcomes study of reverse shoulder arthroplasty performed with use of 5.0-mm peripheral locking screws for baseplate fixat...

The reported rate of complications of reverse shoulder arthroplasty (RSA) seems to be higher than the complication rate of anatomical total shoulder arthroplasty.The reported overall complication rate of primary RSA is approximately 15%; when RSA is used in the revision setting, the complication rate may approach 40%.The most common complications of RSA include instability, infection, notching,...

Massive acromioclavicular joint (ACJ) cysts are an extremely rare cause of shoulder impairment and with limited consensus in its management. We present the first published case report of a patient with a massive ACJ cyst treated with a reverse total shoulder replacement with minimal ACJ excision arthroplasty.
