Arthroscopic stabilization of anterior shoulder instability: a review of the literature.

Abstract

The treatment of anterior glenohumeral instability has been a topic of debate in the recent literature. Current surgical management of shoulder instability has included a variety of open and arthroscopic procedures. Open techniques for anterior reconstruction have been quite successful in preventing recurrent dislocations and continue to be the gold standard of care. In an attempt to address some of the disadvantages associated with open procedures, arthroscopic stabilization procedures have been developed. Arthroscopic capsuloligamentous repair presumably has clear advantages including better cosmesis, decreased perioperative morbidity, and a possible decrease in the loss of external rotation. Advances in arthroscopic instrumentation and improved arthroscopic techniques have increased the popularity of arthroscopic stabilization. The art of diagnosing the anatomic pathology associated with instability and proper patient selection continues to evolve. Most previous reports of arthroscopic stabilization have included small numbers of patients, variable patient pathology, and a variety of surgical techniques, making comparisons between stabilization procedures difficult. Arthroscopy can be valuable in both the confirmation of the degree and severity of the instability and to correct the pathoanatomy responsible for the instability.
