Humerus

The humerus bone provides the skeletal structure of the upper arm. The top of the humerus is spherical (humeral head) and comprises the ball portion of the ball-and-socket shoulder joint. The humeral shaft is a tubular bone that runs from the humeral head above to the humeral condyles below. These condyles make up the upper portion of the elbow joint.

Many injuries of the humerus can be managed non-operatively but severe fractures often require surgery. When a humerus fracture fails to heal (a humeral nonunion) surgical stabilization and bone grafting is the treatment of choice.
