Limited open reduction of the lunate facet in comminuted intra-articular fractures of the distal radius.

Intra-articular incongruity of the distal radius at the radiocarpal joint is a bad prognostic feature; reduction by closed or open operative techniques is important. However, both techniques have limitations. We describe a new technique of reduction of the lunate facet under radiographic control, with very limited operative exposure and tissue trauma. In two cases anatomic restoration of the radiocarpal joint was obtained by this technique and maintained with external and limited internal fixation. Follow-up results are very encouraging. Currently we suggest use of this simple technique when faced with an incongruous radiocarpal joint after unsatisfactory attempts at closed reduction.
