Capitate osteotomy and transposition for type III Kienböck's disease.

The aim of this study was to assess the results of capitate osteotomy and transposition for stage III Kienböck's disease. Capitate osteotomy and transposition combined with an autologous iliac bone graft was carried out in 17 patients. At the final follow-up for a mean of 68 months (range 16-127 months) after surgery, the mean visual analogue scale score was 0.6 (range 0-5). The mean Wrightington wrist function score was 8. The mean grip strength was 79% of the unaffected side. There were 16 satisfactory results. The one unsatisfactory result occurred in a woman who developed a nonunion of the osteotomy. There were no other complications of the surgery. Our results show that capitate osteotomy and transposition is a simple and reliable method for the management of stage III Kienböck's disease.
