Variations of shape and size of glenoid cavity
of scapula is important in order to understand of shoulder dislocation, rotator cuff disease and to determine the meticulous size of the glenoid component in the shoulder arthroplasty.
Similarly, if there is damage to the two ligaments that tie the scapula and clavicle together, or the four ligaments that hold the humerus cap into the glenoid cavity
(of the scapula), a surgeon must debride the area for reattachment and then pull the fibrous tissue back to the site of the tear with monofilament sutures.
Anterior shoulder dislocations not only lead to soft tissue injuries such as labrum, joint capsule and rotator cuff tears, but also sometimes to glenoid cavity
A morphometric study of the patterns and variations of the acromion and glenoid cavity
of the scapulae in Egyptian population.
(a) Coronal plane: the coronal plane consists of the glenoid cavity
centroid, the trigonum spinae, and the inferior angle.

The rotator cuff is important in centring the humeral head in the glenoid cavity
and superior translation of humeral head occurs if their function is compromised.
The labrum is a triangular fibrocartilagenous tissue that increases the depth of the glenoid cavity
while facilitating compression.
It expands the size and depth of the glenoid cavity
, increasing the stability of the glenohumeral joint (Cooper et al 1992).
The tendon of the long head of the biceps brachii along with the supraspinatus contributes to the prevention of superior translation of the humerus from the glenoid cavity
of the scapula.
The glenoid cavity
is located on the lateral angle of the shoulder blade.
The short head arises by a thick flattened tendon from the apex of the coracoid process and the long head arises from the supraglenoid tuberosity at the upper margin of the glenoid cavity
, and is continuous with the glenoid labrum.
The AP projection of the humerus should demonstrate the entire bony anatomy, including the glenoid cavity
Radiological investigations demonstrated an expanded lytic lesion in the scapula near the glenoid cavity
. There was no sensorial dysfunction in his left arm, but he could not use his arm due to pain.
