This study reviews the results of 59 of 84 patients with severe Kienböck's disease who were treated with STT fusion. The average follow-up period was 4 (ranges: 2-8 years).The average arc of wrist extension and flexion was 67° (60% of the contralateral side, 81% of pre-operative range) and that of ulnar and radial deviation was 31° (52% of the contralateral side, 56% of pre-operative range). Pre-operative pain values (VAS) were 56 (non-stress) and 87 (stress) and were significantly higher than the postoperative values of 12 (non-stress) and 41 (stress). Grip strength improved from 45 kPa pre-operatively to 52 kPa postoperatively. The mean modified Mayo wrist score was 63 points. The patients reported low disability in the DASH scores, with an average of 28 points. Our data show that STT fusion is a reliable and effective treatment for pain relief and offers a good functional result in advanced stages of Kienböck's disease. However the long-term effect of this procedure on radioscaphoid and other intercarpal joints is yet to be determined.
