Is the most common complication following fixation of 3 and 4 part proximal humeral fractures and fractures treated with locking plates. The humerus is described as having a proximal region shaft and distal regionthe humerus articulates proximal region by the scapula at the shoulder joint and radius and distal region with ulna at the elbow jointanatomical and surgical neck both of the humerus is highly susceptible to fracture. The humerus is the long bone in the upper arm that sits between.

Humeral head split fractures in which a portion of the humeral head breaks and disrupts the cartilage of the joint. See rotator cuff injuries. The shaft connects both the proximal and distal ends.
