Radioscapholunate arthrodesis for advanced degenerative radiocarpal osteoarthritis

Abstract

Degenerative joint disease affecting the radioscaphoid and radiolunate articulations while sparing the midcarpal joint may be best treated by a radioscapholunate arthrodesis. Limited wrist fusions have been shown to reliably improve pain and maintain some wrist motion. However, nonunion rates have been reported to be relatively high with traditional forms of fixation such as multiple Kirschner wires or cannulated screws. We report a technique of using two angled 2.4-mm distal radius plates to provide locking plate stabilization for radioscapholunate fusions. Our technique also features careful preparation of the planned fusion sites and the use of iliac crest bone graft. We have not had any instances of nonunion or delayed union with this technique thus far. © 2007 Lippincott Williams & Wilkins, Inc.
