Wrist arthrodesis by intramedullary rod fixation: a valuable technique.

Arthrodesis of the wrist with intramedullary rod fixation is a simple technique that provides the opportunity for performing concomitant procedures. Iliac bone graft usually is not required with this technique, as the intramedullary rod is a load-sharing construct that allows compression at the fusion site and facilitates union. Rod removal usually is optional, and the long intramedullary beam effect of the rod can function as an internal splint if fibrous or hypoplastic union occurs. Early mobilization is possible, sometimes with only minimal splinting. The results with use of this technique over a ten year period of time in ten wrists (nine patients) with endstage radiocarpal joint instability are reported.
