Dislocated thumb. Close-up of the dislocated distal phalanx in the thumb of an 8-year-old girl. Dislocation is usually accompanied by tearing of the joint ligaments; it is the tearing that makes this injury so painful. The treatment consists of manipulating the bones back in their correct position which may require a surgical operation.
