3D打印接力截骨导板技术对踝关节骨折的应用价值

Application value of 3D printing relay osteotomy guide in ankle fracture

目的探讨3D打印接力截骨导板技术对踝关节骨折的应用价值。方法选取收治的踝关节骨折患者40例为研究对象,按乱数表法将其分为观察组和对照组各20例。观察组采用3D打印接力截骨导板技术辅助截骨矫正术进行治疗,对照组采用单纯截骨矫正术治疗,比较2组围术期相关临床指标(术中出血量、手术时长、骨折愈合时间),观察2组治疗前后疼痛视觉模拟评分(VAS)、美国骨科足踝外科协会(AOFAS)评分、踝关节活动度(背伸、跖屈、内翻、外翻、旋转)、超敏C反应蛋白(hs-CRP)、白介素-6(IL-6)、白介素-18(IL-18)水平,统计2组术后并发症发生率。结果观察组术中出血量、手术时长、骨折愈合时间明显低于对照组,差异有统计学意义(P<0.05)。观察组治疗后VAS评分明显低于同组治疗前及对照组治疗后,差异有统计学意义(P<0.05),观察组治疗后AOFAS评分明显高于同组治疗前及对照组治疗后,差异有统计学意义(P<0.05)。观察组治疗后背伸、跖屈、旋转明显高于同组治疗前及对照组治疗后,差异有统计学意义(P<0.05);2组治疗后内翻、外翻明显高于治疗前,差异有统计学意义(P<0.05)。观察组并发症发生率明显低于对照组,比较差异有统计学意义(P<0.05)。结论3D打印接力截骨导板技术辅助矫正截骨术治疗可提高临床疗效,加快关节功能的恢复,并对创伤性关节炎有一定的预防价值。

Objective To explore the application value of 3D printing relay osteotomy guide plate in ankle fracture.Methods 40 cases with ankle fracture patients were randomly divided into observation group and control group.The observation group was treated with 3d-printed relay osteotomy guide plate technology to assist osteotomy correction,and the control group was treated with osteotomy correction.The perioperative clinical indicators(intraoperative blood loss,duration of surgery and fracture healing time)of the two groups were compared.The visual analogue score(VAS)of pain before and after treatment and American Orthopedic Foot and Ankle Society score(AOFAS),ankle range of motion(dorsal extension,plantar flexion,varus,valgus and rotation),serum inflammatory factor such as hs-CRP,IL-6 and IL-18 were detected,and the incidence of postoperative complications were compared.Results The intraoperative bleeding volume,operation duration and fracture healing time in the observation group were significantly lower than those in the control group(P<0.05).After treatment,the VAS score in observation group were significantly lower than that in the same group before and after treatment(P<0.05).After treatment,the AOFAS scores in the observation group were significantly higher than those in the same group before and after treatment(P<0.05).The incidence of complications in the observation group were significantly lower than those in the control group(P<0.05).Conclusion 3D printing relay osteotomy guide assisted with orthopedic osteotomy can improve the clinical effects,accelerate the recovery of joint function,and has a certain value on prevention for traumatic arthritis.
