Glenohumeral Instability: Evaluation and Treatment.

Glenohumeral instability encompasses a spectrum of disorders of varying degree, direction, and etiology. The keys to accurate diagnosis are a thorough history and physical examination. Plain radiographs are frequently negative, especially in subtle forms of instability. Computed tomography (CT), CT arthrography, magnetic resonance imaging, arthroscopy, and examination under anesthesia may occasionally yield important diagnostic information. Nonoperative treatment of shoulder instability consists of reduction of the joint (when necessary), followed by immobilization and rehabilitative exercises. The length and the value of immobilization remain controversial. Rehabilitative programs emphasize strengthening f the dynamic stabilizers of the shoulder, particularly the rotator cuff muscles. Both arthroscopic and open techniques can be used for operative stabilization of the glenohumeral joint. Results of these repairs are assessed not only in terms of recurrence rate, but also in terms of functional criteria, including return to athletics. Some standard repairs have declined in popularity, giving way to procedures that directly address the pathology of detached or excessively lax capsular ligaments without distorting surrounding anatomy. Capsular repairs also allow correction of multiple components of instability.

Shoulder Instability-A New Surgical Approach.

Orthopedists have long debated the best surgical treatment for shoulder instability. Now, new information about the inferior glenohumeral ligament complex has led to improved surgical results for both anterior and posterior instability.

Current concepts in the diagnosis and treatment of shoulder instability in athletes.

Glenohumeral joint instability is a fairly common clinical disorder in athletes, especially in sports that involve the throwing motion. The direction of shoulder instability can be anterior, inferior, posterior, or multidirectional. The cause can be trauma, congenital laxity, or voluntary muscle action. Normal shoulders that have been disrupted by injury respond well to surgical correction. Shoulders that have inherently lax supporting structures, as found in patients with atraumatic and voluntary dislocation, have less consistent success with surgical repair. A common condition encountered in the shoulder of a throwing arm is anterior subluxation, which can be diagnosed by the positive apprehension sign and confirmed by arthroscopy. A torn glenoid labrum is a common injury also. Improvement in the diagnosis and treatment of shoulder disorders has been made recently by arthroscopy which allows direct visualization of the joint; many conditions can now be corrected by means of arthroscopic surgery. Radiographic techniques have also been improved.
