Identification of essential anatomic landmarks in performing arthroscopic single- and double-interval slides

Contracted and immobile massive rotator cuff tears, which represent a small percentage of all massive tears, are believed by many to be irreparable. The development of arthroscopic single- and double-interval slides has allowed for the successful anatomic and tension-free repair of the majority of contracted and immobile massive rotator cuff tears. However, the safe and effective performance of interval slides requires clear and precise identification of certain anatomic landmarks, specifically the scapular spine and the base of the coracoid. This report describes how to arthroscopically identify and expose these anatomic landmarks.
