Isolated anatomical neck, slight displacement

A truly isolated fracture of the anatomic neck without involvement of either tuberosity is very rare and somewhat theoretical. 

These fractures are fractures of the anatomic neck with a slight displacement. Although these fractures do not pass through the articular surface, they are termed “articular fractures”; the articular surface is detached from both tuberosities. Quite often, the blood supply of the humeral head is impaired and the risk of subsequent avascular necrosis (AVN) is high.
