了解行胫骨滑移植骨的胫距关节融合效果。

分析2015年1月至2018年12月在青岛市黄岛区第三人民医院骨科行胫距关节融合的病例资料。用疼痛视觉模拟评分法(VAS)和Mazur评分，评估踝关节融合后的疼痛及功能改善；并了解胫距关节融合情况和并发症情况。采用配对样本的Wilcoxon符号秩检验进行比较。

根据纳入、排除标准，共纳入11例研究对象，术前VAS评分5～8分，术后18个月VAS评分1～3分，术后疼痛明显改善(Z＝-2.684，P<0.05)；术前Mazur评分21～77分，术后18个月Mazur评分69～86分，较术前明显改善(Z＝-2.666，P<0.05)。术后12个月后，所有患者的胫距关节均融合，随访期间均未发现感染。有1例59岁的终末期骨关节炎患者术后出现外侧足背皮肤浅感觉减退。

采用胫骨滑移植骨联合空心螺钉进行胫距关节融合对踝关节疼痛及功能改善明显，并发症少、融合率高。

To study the effect of tibiotalar arthrodesis with tibial sliding graft.

The data of patients who underwent tibiotalar arthrodesis in the orthopedics department of the Third People’s Hospital of Huangdao District from January 2015 to December 2018 were analyzed. The visual analogue scale (VAS) and Mazur score were used to evaluate the pain and functional improvement after ankle arthrodesis; and to study the incidence of tibiotalar fusion and complications, the Wilcoxon signed rank test of paired samples was used for comparison.

According to the inclusion and exclusion criteria, a total of 11 subjects were included. The preoperative VAS score was 5-8 and was 1-3 in 18 months after the operation, which showed significant improvement in postoperative pain (Z=-2.684, P<0.05). The Mazur score was 21-77 preoperatively while 69-86 in 18 months postoperatively, which was significantly improved (Z=-2.666, P<0.05). After 12 months of the operation, the tibiotalar joints of all the patients were fused successfully, and no infection was found during the follow-up period. A 59-year-old patient with end-stage osteoarthritis developed superficial sensation of the lateral dorsal skin after surgery.

The use of tibial sliding graft for tibiotalar arthrodesis can significantly improve the pain and function of the ankle joint, with fewer complications and high fusion rate.
