Aja. Santini et Dl. Douglas, 2ND CARPOMETACARPAL JOINT DISLOCATION - AN IMPOSSIBLE SITUATION, International journal of clinical practice, 52(7), 1998, pp. 517-518
We report a case of a seemingly anatomically impossible dislocation of
the second carpometacarpal joint treated by closed manipulation, and
a review the literature. Isolated second carpometacarpal joint disloca
tion is rare, whereas dislocations of the first, fourth and fifth join
ts are more common. A true lateral X-ray is necessary if the injury is
suspected clinically. We recommend that closed reduction under local
anaesthetic is attempted, although the patient should be warned that s
ubsequent open reduction may be necessary if closed reduction fails, C
hronic unreduced dislocations do not produce serious disabilities in t
he hand.
