SLAP lesions of the shoulder.

SLAP lesions are becoming a more recognized cause of shoulder pain and disability. The diagnosis of these lesions is difficult due to vague symptoms and high degree of overlap with other shoulder disorders, and this requires a high index of suspicion. Advances in MR arthrography may lead to advances in preoperative diagnosis of labral tears, but definitive diagnosis, classification, and management is greatly facilitated with the use of the shoulder arthroscopy. Further basic science and clinical research should enhance our ability to manage patients with these lesions effectively.
