目的 分析跟骨骨折采用跗骨窦切口以及反向牵引器微创复位治疗作用。方法 选择实施跟骨骨折治疗的50例患者为研究样本,其研究时间均在2017年2月—2020年2月。对全部患者均实施跗骨窦切口和反向牵引器微创复位治疗,手术过程中利用小钢板实施内固定。观察患者随访情况,比较手术前后患者骨折部位各项指标;不同骨折类型患者治疗总有效率。不同骨折类型病患Bohler角恢复率以及距下关节炎出现率。结果 全部患者手术后均获得随访,随访平均时间是（13.85±1.08）个月。50例患者中有42例（84.00%）距下关节活动范围大于75.00%。手术后跟骨长度以及高度高于手术前,跟骨宽度低于手术前,Gissane角、Bohler角均高于手术前（P<0.05）。Ⅱ型与Ⅲ型病患治疗总有效率依次是96.55%、95.24%（P>0.05）。Ⅲ型病患Bohler角恢复率低于Ⅱ型,距下关节炎出现率高于Ⅱ型（P<0.05）。结论 跟骨骨折病患实施跗骨窦切口以及反向牵引器微创复位治疗,可获得满意的治疗效果。

Objective To investigate the effect of tarsal canal approach and minimally invasive reduction with reverse retractor on calcaneal fracture. Methods Fifty calcaneal fracture patients treated from February 2017 to February 2020 were selected. Tarsal canal approach and minimally invasive reduction with reverse retractor were performed; during surgery, small plate fixation was applied. The follow-up visit data, clinical indicators before and after surgery, as well as total effective rate, Bohler's angle recovery rate, and subtalar arthritis incidence rate among patients with different fracture types were compared. Results All of patients were followed-up after surgery, and the average follow-up time was （13.85±1.08） months. Among the 50 patients, 42 patients （84.00%） had a range of subtalar motion larger than 75.00%. After surgery, the calcaneal length and height were larger than before, the calcaneal width was lower, and the Gissane's angle and Bohler's angle were larger （P<0.05）. The total effective rates in type Ⅱ patients and type Ⅲ patients were 96.55% and 95.24%, respectively （P>0.05）. The Bohler's angle recovery rate in type Ⅲ patients was lower than that in type Ⅱ patients, and the incidence of subtalar arthritis was higher （P<0.05）. Conclusion The tarsal canal approach and minimally invasive reduction with reverse retractor are proven to be effective in treating calcaneal fracture.
