CHAPTER 27 Glenoid Exposure
The technique for glenoid exposure is no less important for implantation of a reverse prosthesis than in cases of unconstrained total shoulder arthroplasty. In fact, certain aspects of reverse prosthesis cases may make glenoid exposure more difficult than in cases of unconstrained total shoulder arthroplasty. First, static subluxation of the proximal humerus may increase the difficulty of proximal humeral retraction during glenoid exposure. Second, as detailed in Chapter 28, a smaller volume of proximal humerus is resected during humeral preparation than in cases of unconstrained shoulder arthroplasty, thus making retraction of the proximal humerus during glenoid exposure more difficult.
