Dislocation of the carpometacarpal joint of the thumb associated with trapezium and Bennett's fractures.

We report a case of a 30-year-old man with a carpometacarpal joint dislocation of the thumb associated with trapezium and Bennett's fractures. This combined injury pattern appears to be very rare. Since, to our knowledge a similar case was not found in the literature. The lesion was managed with closed reduction and percutaneous pinning, resulting in good functional outcome.
