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 is a piece of fibrocartilage (rubbery tissue) attached to the rim of the shoulder socket that helps keep the ball of the joint in place. When this cartilage is torn, it is called a labral tear. Labral tears may result from injury, or sometimes as part of the aging process.
