The glenoid cavity is the part of the scapula (shoulder blade) that forms the socket for the ball (humeral head) The glenoid cavity is relatively shallow but is made deeper by a rim of fibrocartilage called the glenoid labrum, that runs around its periphery and effectively doubles the depth of the socket. The glenoid is a relatively shallow joint compared with for example the hip socket. This allows for the unparalleled flexibility of the shoulder, but also predisposes the joint to instability – the shoulder is the most frequently dislocated joint in the body.
