When this happens, a pocket at the front of the glenoid forms that allows the humeral head to dislocate into it. It is an indication for surgery and often accompanied by a Hill-Sachs lesion, damage to the posterior humeral head. [5] A bony Bankart is a Bankart lesion that includes a fracture of the anterior-inferior glenoid cavity of the ...
The glenoid and labrum are roughened to increase contact surface area and promote re-growth. Locations for the bone anchors are selected based on number and severity of tear. A severe tear involving both SLAP and Bankart lesions may require seven anchors. Simple tears may only require one. The glenoid is drilled for the anchor implantation.
A Hill–Sachs lesion, or Hill–Sachs fracture, is a cortical depression in the posterolateral head of the humerus. It results from forceful impaction of the humeral head against the anteroinferior glenoid rim when the shoulder is dislocated anteriorly.
Also present is a fracture of the greater tuberosity. Inferior dislocation is the least likely, occurring in less than 1%. This condition is also called luxatio erecta because the arm appears to be permanently held upward or behind the head. [18] It is caused by a hyper abduction of the arm that forces the humeral head against the acromion. [19]
Making it an uncommon cause of anterior shoulder instability. Avulsion of this ligamentous complex may occur in three sites: glenoid insertion (40%), the midsubstance (35%) and the humeral insertion (25%). [3] Bony humeral avulsion of the glenohumeral ligament (BHAGL) refers when we have HAGL with bony fracture. [3]
The Ideberg classification is a system of categorizing scapula fractures involving the glenoid fossa. Classification. Type Description Ia Anterior rim fracture Ib
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.
