The junction of the articular portion and the remaining head is called the anatomic neck, whereas the junction between the head fragment and the shaft, below the tuberosities, is termed the surgical neck. The surgical neck is the most common site of proximal humerus fractures. The axillary ...
The circumference of its articular surface is slightly constricted and is termed the anatomical neck, in contradistinction to a constriction below the tubercles called the surgical neck which is frequently the seat of fracture. Fracture of the anatomical neck rarely occurs. The Anatomical Neck (...
The anatomic neck of the humerus is at the junction of the humeral head and the tuberosities. With anatomic neck fractures, the blood supply to the humeral head is disrupted, increasing the chance of avascular necrosis. The surgical neck of the humerus is below the tuberosities. Fractures he...

The anatomic structures involved in fracture of the proximal humerus include humeral head, anatomic neck, surgical neck, and greater and lesser tuberosities. The fractures to the proximal humerus result from a direct blow, fall on an outstretched hand in the elderly, or are related to ...
The proximal humerus has two necks. The anatomic neck is the old epiphyseal plate, and the surgical neck is the metaphyseal area below the humeral head. The blood supply is the anterior and posterior humeral circumflex artery with the axillary nerve as the major nerve of this region. The hume...
Shoulder trauma can damage the anatomic or surgical neck as well as the tuberosities; if trauma is severe, there maybe comminution or fracture-dislocation. [1] Related structural damage When the humerus sustains a fracture, forces of gravity and muscle cause displacement and...KENNETH A. EGOL...
