However, the failure rate following Bankart repair has been shown to increase markedly in patients with significant bone loss from the glenoid ( socket ).
42.
It involves the insertion of a hemispherical implant in place of the glenoid instead of the humerus and the cup section being added to the humerus.
43.
Shoulder subluxation is a common complication of trauma or misuse and is often anterior indicating movement of the humeral head anteriorly out of the glenoid fossa.
44.
Its articular facets with the scapula and glenoid are clearly separate, as in " Sveltonectes " but not " Acamptonectes ".
45.
Ossification of the body begins about the second month of fetal life, by an irregular quadrilateral plate of bone forming, immediately behind the glenoid cavity.
46.
Most agree that the proximal tendon of the long head of the biceps brachii muscle becomes fibrocartilaginous prior to attaching to the superior aspect of the glenoid.
47.
This anatomy includes a large, keeled breastbone, elongated coracoids and a modified glenoid joint in the shoulder, and a semi-rigid rib cage.
48.
This runs from the lower part of the glenoid cavity, downward and backward to the vertebral border, about 2.5 cm above the inferior angle.
49.
The lengthening of the glenoid corresponds with a flattening of the proximal end of the humerus, a feature common in the forelimbs of more advanced stem tetrapods.
50.
In other words, without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle.
