title: Ulnar sesamoid's fracture of the thumb: an unusual injury and review of the literature.
abstract: BACKGROUND
  It concerns an unusual injury which is the result of a violent hyperextension or abduction of the pollex and even less frequently by direct injury.
  
  
  OBJECTIVE
  To increase our sensitivity and observation regarding thumb's injuries, because it is possible a fracture of the sesamoid not to be diagnosed.
  
  
  METHODS
  We present a case of an adult man, 35 years old, who suffered a violent hyperextension of the right pollex. The contribution of digital X-ray examination, which demonstrated a fracture of the ulnar sesamoid of the pollex was very important. The fracture was treated with fixation with elastic bandages for two weeks.
  
  
  RESULTS
  Follow up of the patient six weeks and six months after the injury, demonstrated a total recovery of the function of the pollex and callousness of the fracture, respectively.
  
  
  CONCLUSIONS
  Fracture of sesamoid bones of the thumb is a rare injury, not usually diagnosed, but it has good prognosis when treated properly.
