Isolated dislocation of the carpal-metacarpal joint of the thumb or Trapezio-metacarpal (TMC) is a rare but challenginglesion, and represents 1% of all fractures of the hand.There is still controversy about the best treatment for this pathology. Acute TMC joint dislocation is usually managed bythree treatment modalities: closed reduction and immobilization with a cast, closed or open reduction with Kirschner wiresfixation, and reconstruction or repair of ligaments and capsulorrhaphy. Suture anchor repair is currently being used as theprimary treatment for unstable dislocations.The aim of the present work is to review two cases of carpo-metacarpal dislocation of the thumb treated by reduction andKirschner wires fixation, and show their evolution.
