title: MRI of the rotator cuff and internal derangement.
abstract: Disease to the rotator cuff is the most common cause of shoulder pain and dysfunction in adults. This group of muscles performs multiple functions and is often stressed during various activities. The anatomy and physiology of the rotator cuff is complex and interconnected to other muscle groups in the shoulder. One must take the anatomic status of the rotator cuff tendons into account when planning the treatment of the rotator cuff injury. Diagnostic imaging of the rotator cuff, performed by MRI, provides valuable information about the nature of the injury. In this article, we will review the various types and causes of rotator cuff injuries, normal MR anatomy, function, patho-anatomy, and the biomechanics of the rotator cuff. We will also review shoulder impingement syndromes.
