Broken Forearm: Radius, Ulna, and Both Bone Fractures
Source: Verywell Health
A forearm fracture occurs when there is a fracture of one or both of the bones of the forearm. The two bones of the forearm are the radius and the ulna. Both bones are important for proper motion of the elbow and wrist joints, and both bones serve as important attachments to muscles of the upper extremity.
