Posterior shoulder instability
We provide a review of the recent literature of management of posterior instability of the shoulder. Clarification in defining this problem and an overview of the ever-expanding anatomical injuries associated with increased posterior translation of the humerus are discussed. Particular attention is paid to the caspulolabral ligamentous complex and the rotator interval because these anatomical regions have provided the focus for several recent investigations into both the role played by particular anatomical constraints to shoulder motion and the techniques for manipulation of these constraints to treat these injuries. Several clinical papers have been published recently reporting the results of surgical management of posterior instability, reflecting the trend towards arthroscopic surgery and anatomical reconstruction of these injuries and the associated improvement in outcomes. © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins.
