Abstract: Objective To investigate the clinical effect of arthrodesis in the treatment of thumb first carpometacarpal arthritis. Methods From May 2011 to April 2017, 31 patients with the first carpometacarpal arthritis were treated by arthrodesis, including 8 males and 23 females, aged 42-55 years, with an average age of 48 years. According to Eaton little staging, there were 5 cases in stage Ⅱ and 26 cases in stage Ⅲ. All patients were fixed with Kirschner wire. The first carpometacarpal joint fusion was observed by X-ray film regularly after operation. The grip strength, pinch strength and visual analogue scale （VAS） of pain in each group were measured, and the above results were statistically analyzed. Results All patients were followed up for an average of 26.3 months. Postoperative X-ray showed that all the joints were well fused. The grip strength and interphalangeal pinch strength were increased compared with those before operation, and the VAS score was significantly higher than that before operation. Conclusion Arthrodesis is one of the effective methods to treat the first carpometacarpal arthritis of thumb.

摘要： 目的 探讨关节融合术治疗拇指第一腕掌关节炎的临床疗效。方法 选择自2011年5月至2017年4月,通过关节融合治疗第一腕掌关节炎患者31例,男8例,女23例,年龄在42~55岁,平均48岁。术前依据影像学Eaton-Little分期：Ⅱ期5例,Ⅲ期26例.所有患者均行克氏针固定。术后定期复查X线片观察第一腕掌关节融合情况,分别测量每组握力、指间捏力及痛觉视觉模拟评分（VAS）,对上述结果进行统计学分析。结果 所有患者术后平均随访26.3月。术后X线显示所用关节均融合良好,握力和指间捏力较术前增加,VAS评分较术前下将,差异均有统计学意义。结论 关节融合术是治疗拇指第一腕掌关节炎的有效方法之一。
