摘　　要：目的探索3D打印镜像对比技术在sandersⅡ型跟骨骨折中应用的安全性检验及其临床疗效评价。方法回顾性分析2014年5月~2021月10月,承德医学院附属医院手足外科收治的46例sandersⅡ型跟骨骨折患者。按照术前方案制定的方法,分为镜像对比技术组(23例),放射学技术组(23例)。取镜像对比技术组患侧、健侧的足舟状骨、第五跖骨的测量数据,进行对称性分析,评价其安全性。记录2组术前指标、围手术期及随访指标等评价临床效果。结果镜像对比技术组的患侧、健侧的测量数据,2组比较差异均无统计学意义(P>0.05),应用镜像对比技术实施术前规划具有安全性;手术前计划相关费用、手术前计划相关时间、骨折复位时间,2组间比较差异均有统计学意义(P<0.05)。患者均获得随访,随访时间9~15个月,平均随访(12.48±2.26)个月,骨折愈合率2组间比较差异有统计学意义(P<0.05),Maryland足功能评分2组间比较差异无统计学意义(P>0.05)。结论3D打印镜像对比技术在sandersⅡ型跟骨骨折中应用,具有安全性及可靠性,临床疗效确切,但会增加患者的经济及时间负担。Objective To explore the safety test and clinical efficacy evaluation of 3D printing image contrast technology model in Sanders typeⅡ(sanders I)calcaneal fractures.Methods Retrospective analysis of 46 cases of sandersⅡcalcaneal fracture treated in Afiliated Hospital of Chengde Medical University from May 2014 to October 2021 was made.According to the preoperative plan,patients were divided into mirror image technique group(23 cases)and radiology technique group(23 cases),the measured data of scaphoid bone and fifh metatarsal bone of the affected side and the healthy side were compared by mirror image.The clinical effects were evaluated by preoperative,perioperative and follow-up indexes.Results The measured data of scaphoid bone and fifth metatarsal bone of the affected side and the contralateral side were compared in the mirror image technique group,there was no significant difference between the two groups(P>0.05),so it was safe to use the mirror image technique in preoperative planning.There were significant differences in pre-operative planning related cost,pre-operative planning related time and fracture reduction time between the two groups(P>0.05).All patients were followed up for 9-15 months with an average of(12.48+2.26)months.There was a significant difference in fracture healing rate between the two groups(P>0.05),and there was no significant difference in Maryland foot function between the two groups(P>0.05).Conclusion The application of 3D printing mirror image contrast technique in sandersI type calcaneal fracture is safe and reliable,and the clinical effect is definite,but it will increase the economic and time burden of patients.
