A wrist fracture is a medical term for a broken wrist. The wrist is made up of eight small bones which connect with the two long forearm bones called the radius and ulna. Although a broken wrist can happen in any of these 10 bones, by far the most common bone to break is the radius.
Some fractures are more severe than others. Fractures that break apart the smooth joint surface or fractures that shatter into many pieces (comminuted fractures) may make the bone unstable. These severe types of fractures often require surgery to restore and hold their alignment. An open fracture occurs when a fragment of bone breaks and is forced out through the skin. This can cause an increased risk of infection in the bone
