Abstract
The treatment of Kienböck disease (KD) continues to be controversial. In this study, we report the long-term follow-up outcomes of patients who were diagnosed with stage IIIB KD treated with vascularized capitate transposition. A total of 16 patients were retrospectively reviewed. Baseline clinical information was extracted from medical records, and wrist function was clinically evaluated, including x-ray images. At the final follow-up, wrist pain was severe in 0 patients, moderate in 2 patients, mild in 5 patients, and absent in 9 patients. The mean postoperative active flexion and extension of the affected wrist was significantly improved after surgery compared with before surgery. The postoperative and preoperative mean grip strength was 35 kg and 27 kg, respectively. The Disabilities of the Arm, Shoulder, and Hand score was significantly improved after surgery compared with before surgery. Vascularized capitate transposition for the treatment of Lichtman stage IIIB KD is feasible and associated with improvements in wrist function and pain. Therapeutic IV.
