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. To compensate for the shallow shoulder socket, the joint has a cuff of cartilage called a labrum that forms a cup for the end of the arm bone (humerus) to move within. The labrum circles the shallow shoulder socket (the glenoid) to make the socket deeper. This cuff of cartilage makes the shoulder joint much more stable, and allows for a very wide range of movements (in fact, the range of movements your shoulder can make far exceeds any other joint in the body).
