supraglenoid

The supraglenoid tubercle is a region of the scapula from which the long head of the biceps brachii muscle originates.

Biceps tendonitis originates on the long head of the biceps brachii at the supraglenoid tubercle in 30% of cases.

In cases of Biceps Tendonitis steroids can be injected flouroscopically at the supraglenoid tubercle to reduce pain associated with the pathology.

It is composed of two short-fibred heads separated longitudinally by a thick internal tendon which stretches from the origin on the supraglenoid tubercle to the insertion on the medial radial tuberosity.

The extrinsic muscles include the biceps, triceps, and deltoid muscles and attach to the coracoid process and supraglenoid tubercle of the scapula, infraglenoid tubercle of the scapula, and spine of the scapula.

It originates on the scapula with two tendons: That of the long head on the supraglenoid tubercle just above the shoulder joint and that of the short head on the coracoid process at the top of the scapula.
