关节镜辅助距下关节融合术治疗距下关节炎

Treating subtalar arthritis with arthroscopy assisted subtalar arthrodesis

目的:探讨关节镜辅助距下关节融合术治疗距下关节炎的疗效。方法:选择距下关节炎患者15例,采用关节镜辅助距下关节融合术治疗,观察患者术前及末次随访的AOFAS评分、优良率、VAS评分及融合时间。结果:随访时间(22.3±3.8)个月。术前AOFAS评分、VAS疼痛评分分别为(55.6±4.5)分、(6.9±0.8)分,术后末次随访评分分别为(88.7±4.2)分、(1.5±0.4)分,术前及末次随访评分比较差异具有统计学意义(t=20.826,P=0.00;t=23.383,P=0.00)。随访期间均未出现感染、麻木、皮肤坏死、螺钉断裂等并发症。关节融合时间为(9.4±0.5)周。结论:关节镜辅助距下关节融合术创伤小,对跟骨和距骨的血供破坏少,且操作简便,患者痛苦小,临床疗效较佳,值得临床推广。

Objective：To investigate the curative effect of treating subtalar arthritis with arthroscopy assisted subtalar arthrodesis. Methods： There were 15 cases of patients with osteoarthritis who were selected and treated with arthroscopic assisted subtalar arthrodesis. The AOFAS score,VAS score preoperative or at last follow-up,excellent rate and fusion time were observed. Results： The follow-up time was（ 22. 3 ± 3. 8） months. The preoperative AOFAS score,VAS pain scores were 55. 6 ± 4. 5,6. 9 ± 0. 8,at the last follow-up were 88. 7 ± 4. 2,1. 5 ± 0. 4. There was statistical significance between preoperative and at last follow-up（ t = 20. 826,P = 0. 00;t = 23. 383,P = 0. 00）. During follow-uping,there were no infection,numbness,skin necrosis,screw breakage and so on. Joint fusion time was（9. 4 ± 0. 5） weeks. Conclusion： Arthroscopy assisted subtalar arthrodesis has small trauma,less damage to blood supply of talus calcaneus,and simple operation,little pain. Clinical curative effect is good and worth clinical promotion.
