The present study describes the technique and results of proximal row carpectomy with resection of the head of the capitate and replacement with a pyrocarbon capitate resurfacing implant. The major indication for surgical treatment was arthritic changes on the head of the capitate. Patients were assessed by range of motion, grip strength, pain and functional scoring, and radiographic studies. In most patients, wrist function was improved and pain relief was obtained. This surgical procedure may represent a good alternative to total and partial wrist arthrodesis.
