Shoulder arthroscopy: current indications and techniques.

Abstract

The role of arthroscopy in the diagnosis and treatment of shoulder disorders is evolving. Arthroscopic subacromial decompression is an alternative to open anterior acromioplasty in the treatment of chronic stage II impingement syndromes prior to the development of full thickness rotator cuff tear. Patients with massive and otherwise unrepairable cuff tears have achieved significant pain relief from arthroscopic decompression and debridement of the floppy and irregular cuff margins. Routine repairable full thickness cuff tears are best treated by open reconstruction. The arthroscope is an adjunct in confirming the diagnosis and direction of shoulder instability. Arthroscopic stabilization is most feasible when the anterior glenohumeral ligament/labral complex is detached. The introduction of a metal staple is controversial, however, reported complications are diminishing with experience. Alternate methods of stabilization are being investigated. Effective arthroscopic techniques have been established for the removal of loose bodies, the treatment of calcific tendinitis, septic arthritis, and other disorders. Shoulder arthroscopy will undoubtedly achieve an appropriate place in the armamentarium of the orthopedic surgeon.
