The recovery period for ulnar hawkbone fractures is three months, and the fracture should be fixed in a cast or brace for about four weeks at that time. During the fixation period, the affected limb should be suspended in front of the chest to help the swelling of the limb to subside. If it is clear that there is a continuous bone scab at the fracture end, the external fixation can be removed and the functional training of the elbow joint can be carried out, and the functional training of flexion and extension of the elbow joint can be carried out. If you refuse functional exercise because of pain, it may cause stiffness of the elbow joint. The complete recovery period of ulnar hawk bone fracture takes three months.
