Scaphotrapeziotrapezoid (STT) joint fusion was carried out for pain relief in eight patients with isolated arthritis. Seven patients had satisfactory relief of symptoms. The subjective results were excellent in five, good in two and bad in one patient, who had non-union of the arthrodesis and was also the only patient to develop trapeziometacarpal arthritis. Average grip strength was 0.8 and lateral pinch strength was 0.7 of that in the other hand. There was a very small relative difference in dexterity. There was an average difference of 9 degrees of flexion-extension and 13 degrees of radio-ulnar deviation. It is concluded that for isolated idiopathic STT arthritis, fusion gives very satisfactory results with minimal complications.
对8例孤立性关节炎患者进行舟大多角小多角（STT）关节融合术以缓解疼痛。7例患者症状得到满意缓解。主观结果为优5例、良2例、差1例，该例患者关节融合未愈合，也是唯一发生大多角掌骨关节关节炎的患者。患侧握力平均为健侧的0.8倍，侧捏力为健侧的0.7倍。灵活性方面存在非常小的相对差异。屈伸平均相差9度，桡尺偏平均相差13度。结论是，对于孤立性特发性STT关节炎，融合术效果非常满意，并发症极少。
