Which of the following structures stabilizes the tendon of the long head of the biceps as it travels through the intertubercular groove of the humerus?

Question

BlackTom AI · Accepted Answer

To tackle this question, we first identify what structure stabilizes the tendon of the long head of the biceps as it traverses the intertubercular (bicipital) groove of the humerus.
Option 1: Glenoid Labrum. This fibrocartilaginous rim deepens the glenoid cavity and helps stabilize the shoulder joint overall, but it does not directly stabilize the biceps tendon within the intertubercular groove.
Option 2: Middle Glenohumeral Ligament. This ligament contributes to anterior–posterior stability of the glenohumeral joint and is not specifically involved in securing the long head of the biceps tendon in the bicipital groove.
Option 3: Rotator Cuff Muscles. The rotator cuff provides dynamic stabilization for the humeral head and supports shoulder movement, yet it does not function to stabilize the long head of the biceps tendon within the intertubercular groove itself.
Option 4: Transverse Humeral Ligament. This is the key stabilizing structure for the tendon as it passes through the intertubercular groove; it forms a canal that keeps the long head of the biceps tendon in place, preventing subluxation during arm movements.

Thus, considering the specific role of each structure, the transverse humeral ligament is the one that stabilizes the tendon of the long head of the biceps within the intertubercular groove.
