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 ...
However, displaced fractures in the scapular processes or in the glenoid do interfere with movement in the affected shoulder if they are not realigned properly. [6] Therefore, while most scapular fractures are managed without surgery, surgical reduction is required for fractures in the neck or glenoid; otherwise motion of the shoulder may be ...
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.
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.

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]

Condylar fractures are classified by location compared to the capsule of ligaments that hold the temporomandibular joint (intracapsular or extracapsular), dislocation (whether or not the condylar head has come out of the socket (glenoid fossa) as the muscles (lateral pterygoid) tend to pull the condyle anterior and medial) and neck of the ...
