3D打印辅助治疗后Pilon骨折的效果观察

Effect observation of 3D printing adjuvant therapy in treatment of patients with posterior Pilon fracture after treatment

目的 观察3D打印辅助治疗后Pilon骨折的临床疗效。方法 回顾性分析2012年1月—2020年12月溧阳市人民医院骨科收治的92例后Pilon骨折患者的临床资料,其中术前应用3D打印模拟手术的47例患者设为3D打印组,未应用3D打印模拟手术的45例患者设为对照组。记录2组患者的手术相关并发症,比较2组患者手术时间、术中X线透视次数、手术复位情况、骨折临床愈合时间、末次随访时美国足踝外科协会(AOFAS)足踝评分系统评分及踝关节疼痛视觉模拟评分法(VAS)评分。结果 所有患者均获12~20个月随访。所有患者术后切口均达到Ⅰ期愈合,无患者发生切口感染、皮肤坏死、下肢深静脉血栓、足趾马缰绳畸形等并发症。3D打印组手术时间、术中透视次数分别为(81.4±9.4) min、(13.0±2.3)次,对照组分别为(94.9±11.6) min、(18.4±3.2)次,差异有统计学意义(P<0.05)。对照组有3例患者后踝骨折复位不良,3D打印组无患者发生后踝骨折复位不良,差异无统计学意义(P>0.05)。3D打印组骨折愈合时间、术后AOFAS评分、VAS评分分别为(12.9±1.0)周、(92.8±4.2)分、(1.1±0.8)分,对照组分别为(13.2±1.3)周、(90.8±4.5)分、(1.3±0.8)分,差异无统计学意义(P>0.05)。结论 应用3D打印技术辅助治疗可以优化后Pilon骨折手术方案,缩短手术时间,减少术中透视次数,实现个体化精准治疗。

Objective To observe the clinical effect of 3 D printing adjuvant therapy in treatment of patients with posterior Pilon fracture after treatment.Methods The clinical materials of 92 patients with posterior Pilon fracture from January 2012 to December 2020 in the Department of Orthopedics of Liyang People′s Hospital were retrospectively analyzed.Among them,47 patients with preoperative 3 D printing for simulating operation were selected as 3 D printing group,and 45 patients without 3 D printing for simulating operation were selected as control group.The operation related complications were recorded in both groups,and the operation time,intraoperative X-ray fluoroscopy times,condition of surgical reduction,clinical healing time of fractures,the score of ankle scoring system of the American College of Foot and Ankle Surgeons(AOFAS) and the score of Visual Analogue Scale(VAS) of ankle pain at the last follow-up were compared between the two groups.Results All the patients were followed up for 12 to 20 months.All the patients achieved primary healing after operation,and no patient had complications such as incision infection,skin necrosis,deep venous thrombosis of lower limbs,and checkrein deformity of toes.The operation time and intraoperative fluoroscopy times in the 3 D printing group were(81.4±9.4) min and(13.0±2.3) times respectively,which were significantly shorter and less than(94.9±11.6) min and(18.4±3.2) times in the control group(P0.05).The fracture healing time,postoperative AOFAS score and VAS score in the 3D printing group were( 12.9 ± 1.0)weeks,( 92.8 ± 4.2) points and( 1.1 ± 0.8) points respectively,while were( 13.2 ± 1.3)weeks,( 90.8 ± 4.5) points and( 1.3 ± 0.8) points respectively in the control group,and there were no significant differences between two groups( P > 0.05).Conclusion Application of 3D printing adjuvant therapy can optimize the operation plan of posterior Pilon fracture,shorten the operation time,reduce the number of intraoperative fluoroscopy,and achieve individualized precision treatment.
