A distal radius fracture, also known as wrist fracture, is a break of the part of the radius bone which is close to the wrist. Symptoms include pain, bruising, and rapid-onset swelling. The ulna bone may also be broken. In younger people, these fractures typically occur during sports or a motor vehicle collision. In older people, the most common cause is falling on an outstretched hand. Specific types include Colles, Smith, Barton, and Chauffeur's fractures. The diagnosis is generally suspected based on symptoms and confirmed with X-rays. Treatment is with casting for six weeks or surgery. Surgery is generally indicated if the joint surface is broken and does not line up, the radius is overly short, or the joint surface of the radius is tilted more than 10% backwards. Among those who are cast, repeated X-rays are recommended within three weeks to verify that a good position is maintained. Distal radius fractures are common, and are the most common type of fractures that are seen in children. Distal radius fractures represent between 25% and 50% of all broken bones and occur most commonly in young males and older females. A year or two may be required for healing to occur. Most children with a buckle wrist fracture experience a broken wrist for life and do have an increased chance of re-fracturing the same spot or other adverse effects. Signs and symptoms People usually present with a history of falling on an outstretched hand and complaint of pain and swelling around the wrist, sometimes with deformity around the wrist. Any numbness should be asked to exclude median and ulnar nerve injuries. Any pain in the limb of the same side should also be investigated to exclude associated injuries to the same limb. Swelling, deformity, tenderness, and loss of wrist motion are normal features on examination of a person with a distal radius fracture. "Dinner fork" deformity of the wrist is caused by dorsal displacement of the carpal bones (Colle's fracture). Reverse deformity is seen in volar angulation (Smith's fracture). The wrist may be radially deviated due to shortening of the radius bone. Examination should also rule out a skin wound which might suggest an open fracture, usually at the side. Tenderness at an area with no obvious deformity may still point to underlying fractures. Decreased sensation especially at the tips of the radial three and one half digits ( thumb, index
