The outcomes in 20 patients with advanced Kienböck's disease treated by proximal row carpectomy (seven patients) or limited wrist arthrodesis (13 patients) were reviewed retrospectively. Postoperatively, the results were more satisfactory in terms of wrist pain, the range of wrist flexion-extension, and grip strength following limited wrist arthrodesis than after proximal row carpectomy, although the differences were not statistically significant. We recommend scaphotrapeziotrapezoid arthrodesis in selected patients with advanced Kienböck's disease who have a fragmented lunate.
