The Crest Of The Greater Tubercle Of The Humerus In Anterior View

Description

Framed in anterior view, the proximal humerus rotates subtly to center the crest of the greater tubercle (crista tuberculi majoris) along the lateral lip of the intertubercular sulcus (bicipital groove). Superior to the surgical neck and lateral to the humeral head, this ridge runs longitudinally as a palpable bony landmark on the brachium. As the camera angle eases across the proximal shaft, the groove’s floor and the opposing crest of the lesser tubercle read as parallel borders guiding the viewer’s orientation. Surface anatomy here maps cleanly onto tendon anatomy and common shoulder pain patterns. The crest of the greater tubercle receives the lateral insertion of pectoralis major, while the intertubercular sulcus transmits the tendon of the long head of biceps brachii and its synovial sheath, a region frequently involved in biceps tendinopathy, subluxation with subscapularis tears, and inflammation of the bicipital groove. Motion helps: rotating the humerus makes the lateral lip of the groove easier to discriminate from the more lateral greater tubercle facets that accept supraspinatus, infraspinatus, and teres minor insertions, a distinction that can be hard to teach from a single still. Orthopedic teaching modules can pair this sequence with proximal humerus fracture classification to clarify where tuberosity fragments and tendon insertions sit relative to the bicipital groove, and surgical education can reference it when discussing the deltopectoral approach and tenodesis landmarks. Anatomy and osteology courses will also find it useful for reinforcing anterior surface landmarks of the arm skeleton and Terminologia Anatomica naming conventions.
