Intramedullary Nailing of the hip involves the placement of a long metal rod into the thigh bone, followed by a large single screw up into the femoral head, or the “ball” of the hip joint. A smaller screw is then placed at the end of the rod in order to stabilize it. This procedure requires three relatively small incisions on the side of the leg. Because of the strength of the rod supporting the fractured hip, the patient is able to walk immediately after surgery.
