Opening with a discussion of the indications and pre-operative evaluation of the arthritic shoulder and a review of the anatomy and biomechanics of the shoulder, this comprehensive clinical guide to anatomic shoulder arthroplasty then proceeds to describe the various types of prosthetics and management techniques used in this common surgical procedure. Humeral head resurfacing is described, along with stemmed and stemless replacements, followed by the anatomy and biomechanics of the glenoid using both standard and augmented replacement. Interposition shoulder arthroplasty, revision total shoulder arthroplasty, and hemiarthroplasty of the proximal humerus are likewise elaborated. Additional chapters on complications -- infection, periprosthetic fracture,subscapularis insufficiency and instability -- and rehabilitation techniques round out the presentation.
