Updates to Article Attributes
Body
was changed:
The glenoid labrum is a fibrocartilaginous structure that attaches as a rim to the articular cartilage of the glenoid fossa and acts to deepen and increase the surface area. It acts as a static stabiliser of the glenohumeral joint, preventing dislocation and subluxation at the extremes of range of motion.
Gross anatomy
The glenoid labrum is approximately 4mm4 mm thick and is round or triangular in cross section.
Attachments
The capsule of the glenohumeral joint attaches to the glenoid labrum. The glenoid labrum is continuous with:
- superiorly: tendon of the long head of biceps brachii
- anteriorly
- anterior band of the inferior glenohumeral ligament
- middle glenohumeral ligament (variably)
