Superior labrum anterior posterior lesions of the shoulder: Operative techniques of management

Since the advent of shoulder arthroscopy, pathology of the superior glenoid labrum and biceps anchor has been increasingly recognized as a source of shoulder pain and disability. Additional biomechanical testing has substantiated the role of the superior labrum and biceps anchor in glenohumeral stability. The diagnosis of superior labral injury such as the superior labrum anterior posterior (SLAP) lesion remains difficult, as the history, clinical examination, and radiographic evaluation can only raise suspicion. The ultimate diagnosis of the SLAP lesion can only be made with a well-directed diagnostic glenohumeral arthroscopy. The treatment of SLAP lesions depends on the type of SLAP lesion encountered at arthroscopy. This includes debridement of most type I and III lesions, and repair of type II and many type IV SLAP lesions. In this report, we will present our basic approach towards evaluation and treatment of SLAP lesions at the Southern California Orthopedic Institute.
