Multiple pometacarpal （CMC） joints volar dislocations of car- are uncommon and have been reported rarely. A 25 years old male presented with injury to his left hand 6 days following a road traffic accident. Clini- cal examination revealed gross swelling of the hand and diffuse tenderness over the carpometacarpal area. His ra- diographs of the hand showed volar dislocation of the second, third and fourth CMC joints in association with anextra-articular fracture of the base of thumb metacarpal. He was treated by open reduction and percutaneous fixation using Kirschner wires. The functional results were excellent at one year follow-up.
