SLAP lesions: current concepts.

The presence and significance of superior glenoid labral tears have received increasing attention in the 1990s. The symptoms associated with labral tears can be quite disabling to competitive and recreational athletes alike. Recent basic science and clinical studies have contributed much to the understanding of these injuries, including their association with suprascapular nerve entrapment. This article reviews the current basic science and clinical understanding of SLAP (superior labrum anterior and posterior) lesions in order to guide clinicians and promote further investigation.
