A Bankart lesion is a type of shoulder injury that occurs following a dislocated shoulder. [3] It is an injury of the anterior ( inferior ) glenoid labrum of the shoulder. [ 4 ] When this happens, a pocket at the front of the glenoid forms that allows the humeral head to dislocate into it.
A SLAP tear or SLAP lesion is an injury to the superior glenoid labrum (fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade) that initiates in the back of the labrum and stretches toward the front into the attachment point of the long head of the biceps tendon.
Anterior shoulder dislocation while carrying a frail elder. 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 rotator cuff muscles of the shoulder produce a high tensile force, and help to pull the head of the humerus into the glenoid cavity. The glenoid cavity is shallow and contains the glenoid labrum which deepens it and aids stability. With 120 degrees of unassisted flexion, the shoulder joint is the most mobile joint in the body.
A bone fracture of the shoulder involves a partial or total crack through one of the three bones in the shoulder, the clavicle, the scapula, and the humerus. The break in a bone usually occurs as a result of an impact injury, such as a fall or blow to the shoulder. Fractures usually involve the clavicle or the neck (area below the ball) of the ...
The shoulder joint is considered a ball-and-socket joint. However, in bony terms the 'socket' (the glenoid fossa of the scapula) is quite shallow and small, covering at most only a third of the 'ball' (the head of the humerus). The socket is deepened by the glenoid labrum, stabilizing the shoulder joint. [1] [2]
The lesion is associated with anterior shoulder dislocation. [1] When the humerus is driven from the glenoid cavity, its relatively soft head impacts against the anterior edge of the glenoid. The result is a divot or flattening in the posterolateral aspect of the humeral head, usually opposite the coracoid process. The mechanism which leads to ...
