[Reduction and osteosynthesis of displaced fractures of the distal third of the fifth metacarpal with central medullary bone wires].

We conducted a retrospective study of 80 patients who underwent axial K-wire osteosynthesis for a fracture of the distal third of the fifth metacarpal over an eight year period. We used a technique derived from Foucher's technique. After closed reduction, the fracture was maintained with two or three distal smoothed curved intra-medullary axial K-wires. The final functional result was identical to the opposite side in every case, although with persistent palmar tilt of 14 degrees +/- 11 degrees. The complications were rare. Rotation displacement was always well controlled. In comparison with functional treatment, we recommend this technique in cases of rotation displacement, absence of contact between the fractured ends and marked palmar tilt of the distal fragment.
