Shoulder Arthroplasty: Preoperative Evaluation and Postoperative Imaging

Shoulder arthroplasty procedures have increased over the past few years. Several different arthroplasty options are available for varying indications, such as humeral head resurfacing, hemiarthroplasty, anatomical total shoulder arthroplasty, and reverse total shoulder arthroplasty, with ongoing modifications of prosthesis components and surgical techniques. Arthroplasty complications are encountered from the acute postoperative period to several years postoperatively. This article reviews the more common types of shoulder arthroplasties: their imaging appearances, multimodality imaging assessments for preoperative planning, and complications.
