Radiology of shoulder prostheses.

This article is chiefly limited to the routine radiographic evaluation of shoulder arthroplasties and guidelines to their interpretation. Other imaging modalities for the evaluation of joint replacements are discussed elsewhere in this issue. The basic types of shoulder reconstructions and some of the shoulder replacement designs in previous and current use at The New York Orthopedic Hospital at Columbia Presbyterian Medical Center are illustrated, along with the indications and contraindications of the various types of reconstructions. Their complications and pertinent anatomy are included.
