An avulsion fracture (where a tendon or muscle is torn off its attachment on a bone along with a part of the bone it attaches to) of the supraglenoid tubercle would be associated with which of the following tendons:

Question

BlackTom AI · Accepted Answer

When evaluating an avulsion fracture at the supraglenoid tubercle, we need to recall which tendon attaches there and thus is most likely involved in a bony fragment avulsion.
Option 1: long head of the biceps. The long head tendon of the biceps brachii traverses the intertubercular (bicipital) groove and a portion of its proximal attachment is at the supraglenoid tubercle of the scapula. An avulsion at this site would implicate this tendon, since the biceps long head anchors to the superior glenoid rim and the supraglenoid tubercle.
Option 2: coracobrachialis. This muscle originates from the coracoid process of the scapula, not from the supraglenoid tubercle. Therefore, an avulsion at the supraglenoid tubercle is not associated with the coracobrachialis.
Option 3: brachioradialis. The brachioradialis originates from the lateral supracondylar ridge of the humerus and inserts onto the distal radius. Its attachment points are far from the supraglenoid tubercle, so an avulsion there would not involve this tendon.
Option 4: brachialis. The brachialis originates from the front of the humerus shaft and inserts onto the ulna. Like brachioradialis, its origin does not involve the supraglenoid tubercle, making an avulsion at that site unlikely to be related to the brachialis tendon.
In summary, only the long head of the biceps has a direct attachment to the supraglenoid tubercle, aligning with the described avulsion fracture location, while the other tendons originate elsewhere and are not associated with this specific bony landmark.
