Superior Labrum Anterior to Posterior (SLAP) lesions of the shoulder

Superior Labrum Anterior to Posterior (SLAP) lesions are an abnormality of the superior glenoid labrum and are a significant cause of shoulder pain and instability.Pathology of the superior labrum can pose a significant diagnostic challenge, and therefore a sound knowledge of the relevant anatomy and associated variants is essential in diagnosing and treating these patients. In this article the capsulolabral anatomy and pathomechanics of SLAP lesions are revised. We then review current concepts in the clinical and radiological diagnosis of SLAP lesions and discuss approaches to operative management.
