Humerus Bone, Anterior View

Description

Shown from an anterior orientation, the proximal humerus is seen articulating with the glenoid cavity of the scapula, forming the glenohumeral joint, with the clavicle positioned superiorly at the shoulder girdle. The humeral head faces medially and slightly posteriorly, while the greater and lesser tubercles bracket the intertubercular sulcus on the anterior aspect of the proximal shaft. Distally, the humeral shaft broadens toward the medial and lateral epicondyles, which frame the articular region at the elbow even when the focus remains on the brachium. Joint surface highlighting on the humeral head draws attention to the hyaline cartilage bearing area. Anterior humeral anatomy matters when you are teaching or planning approaches that key off palpable landmarks and tendon corridors. The intertubercular sulcus guides the long head of the biceps brachii tendon and anchors the transverse humeral ligament, a frequent pain generator in biceps tendinopathy and a landmark during open or arthroscopic procedures in the bicipital groove. In proximal humerus fracture fixation or shoulder arthroplasty, appreciating how the tubercles sit relative to the head helps explain rotator cuff tensioning and why malreduction can limit external rotation. Landmarks matter. Use this plate in upper limb osteology labs, anatomy practical exams, and orthopedic teaching files that compare the glenohumeral joint surfaces with distal humeral epicondylar landmarks for orientation. It also suits patient education handouts for shoulder arthroscopy or biceps tenodesis discussions, where an anterior bony roadmap clarifies what is being treated.
