Shoulder Labral Tear
A labral tear is an injury to the glenoid labrum of the shoulder joint. Three bones, the clavicle (collarbone), scapula (shoulder blade), and the humerus (arm bone), form the shoulder joint. The upper end of the humerus is large and rounded, and it sits in a shallow concavity of the scapula called the glenoid fossa. It is the shallowness that allows for such extensive mobility of the shoulder joint, but it makes the joint fundamentally unstable. There is therefore a rim of thick fibrous tissue around the edge of the glenoid fossa that deepens the socket and helps to keep the humerus in position. Several ligaments (bands of strong connective tissue) have their attachments on the glenoid labrum.Learn More
