Rotator Cuff Syndrome

Excerpt

The rotator cuff is an anatomic coalescence of the muscle bellies and tendons of the supraspinatus (SS), infraspinatus (IS), teres minor (TM), and subscapularis (SubSc) surrounding the shoulder joint (see Image. Shoulder Joint Anatomy). Rotator cuff syndrome constitutes a spectrum of diseases across various pathologies associated with injuries or degenerative conditions affecting the rotator cuff. These conditions include subacromial impingement syndrome, bursitis, rotator cuff tendonitis, and partial- (PTTs) or full-thickness (FTTs) rotator cuff tears. Chronic rotator cuff syndrome can elevate the risk of developing glenohumeral degenerative disease and rotator cuff arthropathy. Rotator cuff syndrome is increasingly prevalent with age and is associated with metabolic syndrome, including diabetes, inflammatory arthritis, and thyroid disease.
