The forearm consists of two bones, the radius and the ulna, with the ulna is located on the pinky side and the radius on your thumb side.
Fractures of the forearm can occur at different levels: near the wrist at the farthest (distal) end of the bone, in the middle of the forearm or near the elbow at the top (proximal) end of the bone. They can occur through a direct blow (a fall on the forearm or direct impact from an o bject) or indirect injury. The latter is usually secondary to landing on an outstretched arm.
Forearm fractures can occur as a single (radius or ulna only) or combined (both bones) fracture.
When both bones are fractured at different levels and there is a joint injury at the wrist or elbow, these are described as Galeazzi or Monteggia fractures:
A stable, simple and isolated fracture of the ulna (secondary to a direct blow) can be treated with a cast for about four to six weeks. Your doctor will closely follow your progress with X-rays to assure nondisplacement of the fracture and proper bone healing. During this time, weight lifting and bearing is not permitted.
After removal of the cast, you will start physical therapy with specific exercises to regain full range of motion of your elbow and wrist and rotation of the forearm. Your doctor will increasingly allow you to lift weights according to how your fracture is healing.
Surgery is performed in most of the forearm cases and usually performed through one or two incisions at different levels and sides of the forearm. The fractures are reduced and held together with plates and screws. After surgery your forearm will be put in a short splint for comfort and protection. You will not be allowed to lift weight for six weeks after surgery.
