Since 1985, on the basis of anatomical observation of 50 fresh adult specimens, we designed the transposition oF vascularized capitate bone carrying the dorsal branche of the anteriot interosses artery to replace the damaged lunate bone from avascular necrosis. The operation had been done in 6 patients and the follow-up observation (from 6 months to 4 years) showed that the operation was satisfactory. The anatomic basis, the advantages and disadvantages, and the surgical indications were discussed.
