Arthroscopic repair of anterior glenohumeral instability and rotator interval lesions.

As the techniques and instrumentation for shoulder arthroscopy continue to improve and evolve, its role in the treatment of anterior shoulder instability progresses also. With more surgeons becoming familiar with these advancements and techniques, arthroscopic stabilization results continue to improve and help arthroscopy become the "preferred method" for the treatment of shoulder instability. Adjunct procedures such as closure of the rotator interval also are helping to improve our arthroscopic results and are an important improvement in our understanding of the pathoanatomy of shoulder instability repairs.

Biomechanical comparison of reconstruction techniques for disruption of the acromioclavicular and coracoclavicular ligaments.

Injuries to the acromioclavicular joint are common. For selected injuries, operative reconstruction is recommended. The purpose of the current study was to compare three reconstruction procedures: (1) nine strands of woven polydioxanonsulphate (PDS II) suture passed through the clavicle and around the coracoid; (2) procedure No.
