In other words, without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle. The anterior and posterior directions of the glenoid fossa are more susceptible to shear force perturbations, as the glenoid fossa is not as deep relative to the superior and inferior ...
The glenoid labrum (glenoid ligament) is a fibrocartilaginous (but not fibrocartilage, as previously thought) structure attached around the rim of the glenoid cavity on the shoulder blade. The shoulder joint is considered a ball-and-socket joint .

A dislocated shoulder is a condition in which the head of the humerus is detached from the glenoid fossa. [2] Symptoms include shoulder pain and instability. [2] Complications may include a Bankart lesion, Hill-Sachs lesion, rotator cuff tear, or injury to the axillary nerve. [1]
The glenoid cartilage underneath the labrum in the glenohumeral (GH) joint is disrupted by glenolabral articular disruption. [5] The articulation of the humeral head inside the glenoid fossa of the scapula forms the GH joint itself, which is a synovial ball and socket joint.
The Latin terms supra and infra meaning above and below respectively refers to the tubercles location in relation to the glenoid cavity.
