S52: Fracture of forearm

S52.7: Multiple fractures of forearm

There are 2 bones in the forearm, the ulna and the radius. The ulna is on the side where your little finger is. The radius is on the side where your thumb is. Both bones in the forearm have an upper, middle and lower section. The top ends of ulna and radius, along with the humerus, form the elbow joint. The ulna and the radius both have a long, straight section in the middle. The lower ends of the ulna and the radius are connected to the hand by the wrist.

Your ulna and radius may be broken in more than one place.
