Abstract
Carpometacarpal dislocations may be dorsal, volar or divergent type but most are dorsal with involvement of fourth and fifth metacarpal. Isolated volar dislocation of the fifth carpometacarpal joint is an uncommon injury specially when there is no associated fracture. We report a case of radial palmar dislocation of the base of fifth carpometacarpal joint associated to compression of the fourth interdigital nerve in the hand.
