Carpometacarpal and metacarpophalangeal joints of the thumb exhibit relatively wide range of motion, which may act as a shock absorber. So dislocation of these joints are relatively rare. Furthermore, a complete dislocation of the thumb metacarpal by simultaneous dislocation of carpometacarpal and metacarpophalangeal joints is a very rare injury, and only a few cases were reported in the English literatures. The authors will present a case of a complete dislocation of the thumb metacarpal in a 31 years old female.
