Transverse Ligament Of The Humerus, Lateral View

Description

Shown from a lateral perspective of the male shoulder, the proximal humerus is oriented with the humeral head articulating medially with the glenoid cavity of the scapula, while the clavicle runs anterior to the acromion toward the manubrium. Spanning the intertubercular sulcus between the greater and lesser tubercles, the transverse humeral ligament forms a fibrous roof over the tendon groove as it bridges anteriorly across the proximal humerus. Superiorly, the acromion overhangs the glenohumeral joint, and inferiorly the surgical neck marks the transition toward the humeral shaft. Portions of the upper thorax, including ribs and adjacent thoracic vertebrae, provide skeletal context posterior to the shoulder girdle. Clinically, this structure matters because it relates directly to the course and stability of the long head of the biceps brachii tendon in the bicipital groove, a frequent pain generator in anterior shoulder complaints. Biceps tendinopathy, tenosynovitis, and medial subluxation of the tendon are assessed with attention to the groove and its overlying soft tissues, and surgeons encounter this region during open or arthroscopic biceps tenodesis and procedures addressing rotator interval pathology. A small band, big consequences. Educators will find this lateral view effective for clarifying the spatial relationship of the transverse humeral ligament to the greater and lesser tubercles in gross anatomy, kinesiology, and orthopedic modules on the shoulder. It also supports figures for clinical anatomy texts discussing anterior shoulder pain, bicipital groove palpation landmarks, and operative orientation during proximal humerus exposure.
