In posterior shoulder dislocation, the humeral head is displaced posteriorly out of the glenoid cavity. This injury is frequently associated with internal rotation where the humeral head rotates internally, altering its usual elliptical contour to a more rounded shape, creating the "light bulb" appearance.
Grade Description 0: No osteoarthritis signs 1: Mild: increased osteosclerosis; minor joint space narrowing (normal joint space is at least 2 mm at the superior acetabulum) [7] no or minor loss of head sphericity; 2: Moderate: small bone cyst; moderate joint space narrowing; moderate loss of head sphericity; 3: Severe: large bone cysts

A SLAP lesion (superior labrum, anterior to posterior) is a tear where the glenoid labrum meets the tendon of the long head of the biceps muscle. Symptoms include increased pain with overhead activity, popping or grinding, loss of strength, and trouble localizing a specific point of pain. [ 3 ]
Shoulder arthritis is a clinical condition in which the joint that connects the ball of the arm bone (humeral head) to the shoulder blade socket (glenoid) has damaged or worn out cartilage. Normally the ends of the bone are covered with hyaline articular cartilage , a surface so smooth that the friction at the joint is less than that of an ice ...
Glenolabral articular disruption lesions usually occur from forceful adduction of the humeral head onto the glenoid fossa. Shear force might also be present. Shear force might also be present. This results in varying degrees of underlying cartilage damage as well as a superficial tear along the anterior-inferior aspect of the labrum.
The cuff adheres to the glenohumeral capsule and attaches to the head of the humerus. [3] Together, these keep the humeral head in the glenoid cavity, preventing upward migration of the humeral head caused by the pull of the deltoid muscle at the beginning of arm elevation. The infraspinatus and the teres minor, along with the anterior fibers ...
The ligaments may be best seen by opening the capsule at the back of the joint and removing the head of the humerus: [2]. One on the medial side of the joint passes from the medial edge of the glenoid cavity to the lower part of the lesser tubercle of the humerus.
