[Traumatic axial separation of the radial mid carpal joint. Case report and review of the literature].
The authors report a case of traumatic axial disruption of the radial mid carpal joint. This unusual type of scaphotrapezo-trapezoïdal dislocation occurred after a motorcycle accident. Open reduction and pinning was performed. At three years and six months follow up, clinical exam showed less power thumb pinch than the other side. Arthritic changes were noted on X-rays control, but a good range of motion was preserved. Radial mid carpal disruption is uncommon. It includes the separation of the trapezium, trapezoïdal, first and second metacarpal bones from the remaining wrist. Only 13 other similar cases were reported in literature for the last three decades. Mechanism of the injury and treatment are discussed.
