A Follow-up Study of Surgical Treatment for Kienböck's Disease

From 1988 to 1994, we treated eleven cases of Kienbock's disease surgically.Five cases were treated with radial shortening, one with radial and ulnar shortening, four with radial shortening associated with vascular bundle transplantation, and one with resection of a fragment.Clinical results of all cases were almost good, but radiographical findings of each procedure showed little improvement.In the cases with radial shortening and vascular bundle transplantation, investigation using magnetic resonance imaging (MRI) showed improvement of circulation of the lunate.Therefore, we suggest the significance of performing revascularization with radial shortening.
