Posterior arthroscopic subtalar arthrodesis for end- stage arthropathy

摘要:

[目的] 探讨后侧入路关节镜距下关节融合术治疗终末期关节病的临床疗效。[方法] 回顾性分析 2016 年 8 月— 2019 年 6 月采用后侧入路关节镜距下关节融合术的 31 例严重距下关节炎患者资料。总结围手术期资料及随访临床和影像资料。[结果]所有患者均顺利完成手术，无术中并发症，随访时间平均(19.1±2.9)个月。随时间推移，31 例患者 VAS 评分显著降低(P＜0.05)；AOFAS 评分显著增加(P＜0.05)。影像方面，末次随访时 30 例后足对线正常，仅 1 例存在轻度内翻(＜5°)，与术前相比后足对线显著改善(P＜0.05)。末次随访时 X 线片显示融合率为 100%。[结论]后侧入路关节镜距下关节融合术治疗终末期距下关节病疗效显著，术后融合率高。

Abstract:

[Objective] To evaluate the clinical efficacy of posterior arthroscopic subtalar arthrodesis for the end- stage arthropathy. [Methods] A retrospective study was conducted on 31 patients who underwent posterior arthroscopic subtalar arthrodesis for severe subtalar arthritis in our hospitals from August 2016 to June 2019. The perioperative, follow-up and imaging data were summarized. [Results] All the patients had operation performed successfully without intraoperative complications, and followed up for (19.1±2.9) months on an average. The VAS scores of 31 patients significantly decreased (P＜0.05) , whereas the AOFAS scores significantly increased over time (P＜0.05) . In terms of imaging examination, 30 patients had normal hindfoot alignment, whereas the remaining one patient got mild varus (＜5°) , which did not impact the joint function. By the time of the latest follow-up, all the 31 patients got solid subtalar fusion with fusion rate of 100%. [Conclusion] This posterior arthroscopic subtalar arthrodesis is effective treatment for end-stage subtalar arthropathy with a high fusion rate.
