Humeral neck anatomy. The anatomical neck of the humerus is obliquely directed forming an obtuse angle with the body of the humerus. Neck of the humerus the anatomical neck is the groove that surrounds the articular surface of the head of the humerus. The anatomical neck of the humerus is located distal to the head of the humerus at an oblique angle to the shaft of the humerus.

The rhythm between the scapula and the humerus is a very important one for adequate shoulder function. Average retroversion values are 1833 the proximal humeral articular surface is a segment of a sphere that measures from 37 to 57 mm in diameter 5. The superior aspect of the articular surface is 8 mm above the greater tuberosity.

The average humeral neck angle is 130. This is where the joint capsule is attached. Anatomy the humerus has two large knobs at the top of the bone called the greater and lesser tubercles which join the scapula in order to provide movement along with stability.

The surgical neck of the humerus on the other hand is a constriction of the humerus located inferior to the greater and lesser tubercles. The anatomic neck of the humerus refers to the location of the physeal plate during development. During growth bone forms at the physeal plate as the child ages.
