Etiology

When considering the possible causes of rotator cuff disease, mechanical impingement of the rotator cuff is considered the most common recognizable source of recurring pain and disability in the active population. Neer’s classic work served to organize the clinician’s approach to rotator cuff disease and, most importantly, to define rotator cuff pathology as a spectrum […]

Anatomy and Pathophysiology

In the normal shoulder, the coordinated muscle tension within the rotator cuff compresses the humeral head, keeping it centered within the glenoid fossa. By coupling with the force of the deltoid, a fulcrum is created that allows strength through a wide arc of motion.

The overlying subacromial bursae reduces friction between the tendonous cuff and […]

Scapula

The scapula is a flat, triangular-shaped bone that serves as the articulating surface for the head of the humerus as well as provides areas for 17 muscle attachments. With the arm at the side, the scapula overlaps the dorsal surfaces of the second to seventh ribs. It has three prominent projections: the spine, the coracoid […]

Impingement syndrome: Inflammatory condition of the soft tissues of the subacromial space Most common cause of presentation for shoulder complaints to a physician’s office (>50% of all shoulder complaints) Represents a continuum, progressing from acute bursitis, to chronic bursitis, to partial-thickness tears […]
