We used intercarpal fusion combining transfer of pedicled pisiform bone clinically evaluate its effectiveness in treating Kienbock disease. Eight cases of Kienbock disease (stage III) were treated with thismethod. The lunate bone was removed and was replaced with pedicled pisiform bone. Intercarpal fusion included scaphoid, trapezium and trapizoid bones fusion in 5 cases and scaphoid, capitate bone fusion in3 cases. The patients were followed up for 8-44 months with an average of 29 months. Complete reliefof pain was obtained in all the patients. The ranges of motion of the wrist were improved: the extensionand flexion averaged 58. 8% and 51. 4% of the normal side, respectively. The grip strength was increased by 46. 9%. Radiograph showed normal location of transferred pisiform bone without osteosclerosis. Atrophy of pisiform bone was found 2 years postoperatively in one case. The intercarpal fusionwas stable. Six of the eight patients returned to their original job. We conclude the technique of intercarpal fusion combining transfer of pedicled pisiform bone is an effective method to treat ischemic necrosis stage III of lunate bone'
