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.
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 ...
A scapular fracture is a fracture of the scapula, the shoulder blade.The scapula is sturdy and located in a protected place, so it rarely breaks. When it does, it is an indication that the individual was subjected to a considerable amount of force and that severe chest trauma may be present. [1]
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]
Because of the mechanism of injury, apprehension of anterior dislocation is common with provocative maneuvers. Hill–Sachs lesions have been classified as "engaging" or "non-engaging", with engaging lesions defined by the ability of the glenoid to sublux into the humeral head defect during abduction and external rotation.
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.
Mandibular fracture, also known as fracture of the jaw, is a break through the mandibular bone. In about 60% of cases the break occurs in two places. [1] It may result in a decreased ability to fully open the mouth. [1] Often the teeth will not feel properly aligned or there may be bleeding of the gums. [1]
In over 95% of shoulder dislocations, the humerus is displaced anteriorly. [8] In most of those, the head of the humerus comes to rest under the coracoid process, referred to as sub-coracoid dislocation. Sub-glenoid, subclavicular, and, very rarely, intrathoracic or retroperitoneal dislocations may also occur. [9]
