Scapho-trapezio-trapezoid arthrodesis in the treatment of Kienböck's disease. A study of 16 cases.
Sixteen scapho-trapezio-trapezoid arthrodeses were performed for Kienböck's disease. In ten cases, a prosthetic replacement of the lunate was inserted at the same time. Clinical results were good with regard to pain and fair with regard to grip strength which was improved by an average of 32%. In contrast, the arc of flexion-extension was 38% less than on the unoperated side. Long-term radiographic assessment showed the efficacy of the procedure in maintaining carpal height. Biomechanical observations and a review of poor results showed the limits of the method and the importance of correct positioning of the scaphoid. We concluded that triscaphe arthrodesis was a useful procedure for the treatment of Kienböck's disease in Decoulx's stage 3.
