Advances in the understanding of anterior instability of the shoulder.
Anterior instability involves a spectrum of disease ranging from the obvious acute first-time dislocation to the athlete presenting with shoulder pain and no history suggestive of instability. It is important to recognize the pathophysiology and how it relates to this spectrum of disease. The arthroscope has helped to identify the underlying pathology in both acute and chronic situations. Diagnostically, a history of a painful shoulder, especially in the athlete, should suggest anterior instability. Tests of translation, apprehension, and the use of local anesthetic can be useful. Arthroscopy is used in situations in which the diagnosis is unclear. The management of anterior instability should emphasize strengthening of the rotator cuff and scapular stabilizers. Surgical repair requires correction of the underlying pathology with minimization of damage to other structures. Arthroscopic management of anterior instability includes repair, debridement of intra-articular lesions, and the possibility of acute correction of the pathoanatomic lesions.
