[Anterior traumatic axial disruption of the middle carpal joint. Case report with literature review].

We report a case of traumatic axial disruption of the radial mid carpal joint. This unusual type of scaphotrapezo-trapezoïdal dislocation occurred after falling from a height. We performed open reduction and wire fixation. At 12months follow-up, functional outcome was satisfactory with good muscle strength (clamping force, grip strength and pinch grip: 90% compared to the opposite side) and good range of motion was preserved. Work was resumed at the tenth week. Radial midcarpal disruption is uncommon. It includes the separation of the trapezium, trapezoïdal, first and second and third metacarpal bones from the remaining wrist. This pattern of carpal derangement has not been previously described in the literature. Mechanism of the injury and treatment are discussed.
