Computer-generated bone models in the planning of osteotomy of multidirectional distal radius malunions.

Abstract

Computer-assisted design and manufacturing technology has been used to create solid models of five unusually complex, multidirectional malunions of distal radius fractures. Preoperative planning was dramatically enhanced by the ability to perform the surgical procedure on these models, with a model of the uninjured limb used for comparison. All five patients had significant malunions, with malrotation in the horizontal plane in five and an impacted articular fragment in two. A satisfactory outcome was achieved in each case.
