Anatomical terms of bone [edit on Wikidata]

The supraglenoid tubercle is a region of the scapula from which the long head of the biceps brachii muscle originates. It is a small, rough projection superior to the glenoid cavity near the base of the coracoid process. The term supraglenoid is from the Latin supra meaning above and glenoid meaning socket or cavity.^[1]

Clinical relevance

Biceps tendonitis originates on the long head of the biceps brachii at the supraglenoid tubercle in 30% of cases. The symptom is generally anterior biceps instability but the disease can also be characterized by chronic anterior shoulder pain which radiates towards the lateral part of the elbow.^[2] In cases of biceps tendinitis, steroids can be injected fluoroscopically at the supraglenoid tubercle to reduce pain associated with the pathology.^[3]
