计算机辅助设计联合3D打印技术在颈椎骨折脱位的临床运用分析

Clinical application of computer-aided design combined with 3D printing technology in cervical spine fracture and dislocation of cervical spine fracture

目的分析计算机辅助设计联合3D打印技术在颈椎骨折颈椎骨折脱位的运用效果。方法颈椎骨折或脱位病人70例根据治疗方式不同分为两组:观察组35例采用计算机辅助设计联合3D打印技术辅助手术治疗,对照组35例采用常规CT辅助手术治疗。记录分析两组病人治疗过程中的指标参数以及术后螺钉置钉位置情况。分析评价治疗前后JOA评分和VAS情况,统计并分析病人术后不良反应发生情况。结果观察组病人术中出血量(148.9±8.2)ml、手术时间(95.2±10.4)分钟、排气时间(2.5±1.1)天,均优于对照组的(208.8±9.1)ml、(108.3±7.6)min和(3.1±0.6)天,观察组病人术后置钉成功率85.71%高于对照组的68.57%(P<0.05)。两组病人治疗后JOA评分均高于治疗前,观察组治疗后JOA评分(15.64±1.48)分高于对照组的(14.73±1.51)分;两组病人治疗后VAS评分均低于治疗前,观察组治疗后病人VAS评分(3.16±0.46)低于对照组的(3.42±0.33)分(P<0.05)。观察组不良反应发生率8.57%,低于对照组的17.14%,差异不具有统计学意义(P>0.05)。结论颈椎骨折颈椎骨折脱位病人采用计算机辅助设计联合3D打印技术进行治疗,具有手术时间短、损伤小、治疗效果好及安全性高等优点,值得临床上推广应用。

Objective Exploration and analysis of the clinical application of computer-aided design combined with 3 D printing technology in cervical spine fracture and dislocation of cervical spine fracture.Methods The clinical data of 70 patients with cervical spine fractures and dislocations who were treated in our hospital were collected and divided into two groups according to different treatment methods:The observation group(35 cases)was treated with computer-aided design combined with 3 D printing technology,and the control group(35 cases)was treated with conventional CT-assisted surgery.The parameters of the operation time,intraoperative blood loss,and exhaust time of the two groups were recorded and analyzed,and the position of the postoperative screw was set.Analysis and evaluation of JOA score and VAS before and after treatment.Statistics and analysis of the occurrence of postoperative adverse reactions in patients.Results The operation time(95.2±10.4)min,the amount of bleeding(148.9±8.2)ml and the exhaust time(2.5±1.1)d in the observation group were better than the control group[(108.3±7.6)min,(208.8±9.1)ml,(3.1±0.6)d](P<0.05).The success rate of postoperative fixation(85.71%)in the observation group was higher than that in the control group(68.57%)(P<0.05).The JOA scores of the two groups were higher than those before treatment.The JOA score of the observation group(15.64±1.48)was higher than that of the control group(14.73±1.51)(P<0.05).The VAS scores of the two groups were lower than before treatment.The VAS score of the patients(3.16±0.46)was lower than that of the control group(3.42±0.33)(P<0.05).The incidence of adverse reactions in the observation group(8.57%)was lower than that in the control group(17.14%),the difference was not statistically significant(P>0.05).Conclusion Cervical spine fractures and cervical dislocation patients with computer-aided design combined with 3 D printing technology for treatment,with short operation time,low damage,good therapeutic effect and high safety,it is worthy of clinical application.
