Arthroscopy of the sternoclavicular joint.

Abstract

Traditionally, an open approach has been required to undertake any surgical intervention for intra-articular sternoclavicular joint pathology. This in itself carries a certain operative morbidity, including damage to the underlying mediastinal structures and damage to the sternoclavicular and costoclavicular ligaments, with subsequent joint instability and unsightly scarring. This technical note describes an arthroscopic approach to the sternoclavicular joint that reduces this morbidity. The evolution of the technique including the rationale for portal placement and the angle of instrument insertion is explained. Experience of over 50 arthroscopic procedures including diagnostic arthroscopy, discectomy, excision of loose bodies, and washout and debridement after infection and excision of the medial end of the clavicle for osteoarthritis is detailed.
