Medical Definition of glenoid labrum. : a fibrocartilaginous ligament forming the margin of the glenoid cavity of the shoulder joint that serves to broaden and deepen the cavity and gives attachment to the long head of the biceps brachiiâcalled also labrum.
The labrum can tear as a result of trauma or with wear and tear. The normal labrum is a smooth ring of tissue that surrounds the socket of the shoulder. Labral tears are often caused by a direct injury to the shoulder, such as falling on an outstretched hand. The biceps tendon attaches to the top part of the labrum. The biceps is the large muscle on the front of your upper arm.
