Forearm

The radius and ulna bones provide the skeletal structure of the forearm. The top of the radius is known as the radial head and the top of the ulna is known as the olecranon. These two bones make up the lower portion of the elbow joint. The bottom of the radius is known as the distal radius and the bottom of the ulna is known as the ulna styloid. These two bones make up the upper portion of the wrist.

Some forearm injuries can be managed non-operatively but severe fractures and dislocations always require surgery. When the bones of the forearm fail to heal (a radius or ulna nonunion, or both) surgical stabilization and bone grafting is the treatment of choice.
