Crest Of The Greater Tubercle Of The Humerus In Anterior View

Description

Crest of the greater tubercle (lateral lip of the intertubercular sulcus) is highlighted on the proximal humerus in anterior view, forming a sharp longitudinal ridge on the anterolateral aspect of the bone. Medial to this crest, the bicipital (intertubercular) groove descends between the greater and lesser tubercles, with the lesser tubercle positioned more anterior and medial. Superiorly, the crest approaches the greater tubercle and surgical neck region, while inferiorly it continues toward the lateral surface of the humeral shaft. Orientation is straightforward. Clinically, this ridge matters because it marks the insertional footprint of pectoralis major on the lateral lip of the bicipital groove, a key landmark when teaching shoulder and anterior arm anatomy and when discussing tendon rupture patterns. In proximal humerus fracture assessment, the relationship between the crest, the bicipital groove, and the tubercles helps you communicate fragment position (greater tuberosity displacement versus involvement of the surgical neck) and anticipate rotator cuff dysfunction nearby. The fixed anterior perspective also supports surgical planning discussions around the deltopectoral approach, where the intertubercular groove and its lateral lip guide orientation to the long head of the biceps tendon and adjacent soft-tissue attachments. Use this illustration in gross anatomy and musculoskeletal modules to anchor the “lips and floor” concept of the intertubercular sulcus, and in orthopedic and sports medicine teaching to localize pectoralis major insertion and correlate it with tendon avulsion or proximal humerus trauma. It also suits textbook figures and exam items that ask learners to identify the crest of the greater tubercle in anterior orientation. Anatomical accuracy verified by SciePro's Medical Advisory Board.
