Transverse Ligament of the Humerus, Anterior View

Description

Positioned at the proximal humerus, the transverse humeral ligament spans laterally between the greater tubercle and the lesser tubercle, crossing the intertubercular sulcus (bicipital groove) on the anterior aspect of the shoulder. Deep to this bridge sits the tendon of the long head of the biceps brachii as it enters the groove, while the humeral head lies medial and superior as it faces the glenoid cavity of the scapula. Superiorly, the acromion overhangs the glenohumeral joint, and the clavicle may be suggested anterior to the acromion depending on crop. Tight, local anatomy. Functionally, this small band matters because it frames a common pain generator: instability or inflammation of the long head of biceps tendon in the bicipital groove, often discussed in the context of biceps tendinopathy and associated rotator cuff disease. An anterior, close-up perspective also supports teaching of palpable and surgical landmarks, since the intertubercular sulcus and tubercles guide orientation during shoulder arthroscopy and open approaches to the proximal humerus. It is also a useful reminder that the so-called transverse humeral ligament is frequently described as a capsular extension or fibers from the subscapularis and supraspinatus tendons, a point that comes up in anatomy lab and in operative reports. Orthopaedic and sports medicine educators will find this image well suited for lectures on biceps pulley anatomy, long head biceps pathology, and proximal humerus surface landmarks, as well as for atlas plates that need a clean anterior view without distracting musculature. Medical publishers can pair it with discussions of bicipital groove tenderness, SLAP-adjacent symptom patterns, and surgical tenodesis orientation.
