[STT arthrodesis as therapy of lunate necrosis in an advanced stage].

The results of STT-fusion for treatment of advanced Kienböck's disease were investigated in a retrospective study. The follow-up included 25 of 28 patients, the average follow-up time was 39 months. Pain relief, range of motion, grip strength and X-ray findings were the most important criteria for rating the results. On the one hand, there was a decrease of range of motion, but on the other hand, grip strength improved markedly. Of course, one part of the decrease of pain is caused by the performed partial denervation of the wrist. However, the decrease of pain was impressive.
