Trans-trapezium carpo-metacarpal dislocation of the thumb.
We report a case of carpo-metacarpal dislocation associated with an isolated horizontal fracture of the trapezium. It is a rare lesion which is difficult to diagnose by standard radiography, and CT may be necessary for the diagnosis and correct treatment. In our case, stable osteosynthesis was achieved by internal screw fixation, and at follow-up there was an unrestricted, painless range of motion of the thumb.
