Abstract：
:MR imaging of the postoperative shoulder after instability surgery is challenging. The radiologist must be familiar with surgical procedures, altered anatomy, and expected postoperative findings for correct interpretation of normal findings versus a true pathology. Artifacts from metallic hardware or abrasions further complicate MR image interpretation, but are reduced with metal artifact reduction techniques. This article focuses on capsulolabral surgery, bone block transfers, and humeral bone loss procedures in patients with shoulder instability and their postoperative imaging evaluation. Surgical procedures and common complications are explained, and normal and pathologic postoperative imaging findings are presented.
