摘要(Abstract)：

[目的]探讨微骨折技术应用于关节镜下踝关节融合术的临床疗效,尤其是伴有踝关节内外翻畸形时,能否通过微骨折技术提升踝关节融合率,避免关节内植骨。[方法]回顾分析2011年1月～2017年12月本科关节镜下踝关节融合术治疗的终末期关节炎患者48例。依据术前站立位踝关节正位X线片测量胫距关节面夹角,将内外翻角度在10°～20°的19例患者分为A组,将10°以内的29例患者分为B组。常规进行关节镜下踝关节融合术,术中应用微骨折技术,比较两组术后踝关节骨性融合时间和美国足踝外科学会踝-后足评分(AOFAS)等评估指标。[结果]术后2例患者出现足背前外侧感觉麻木,术后6周缓解,术后3个月感觉恢复。48例患者平均随访(25.60±7.87)个月,术后12周复查X线片提示A组患者骨性融合率与B组相比差异有统计学意义(P<0.05)。术后两组病例均达到骨性融合,但两组融合时间差异有统计学意义(P<0.05)。术后末次随访时两组AOFAS评分差异无统计学意义(P>0.05)。[结论]对于胫距关节面夹角内外翻在10°～20°的终末期踝关节炎患者,在关节镜辅助下踝关节融合术中应用微骨折技术可避免关节内植骨,近期临床疗效满意,但对于踝关节内外翻畸形明显时,骨性融合时间会延长。
