摘　　要：目的探讨3D打印技术在骨盆骨折修复术中的应用价值。方法选取2015年1月~2016年5月我院收治的42例骨盆骨折修复患者作为研究对象。采用随机数字表法将其分为对照组、观察组,每组21例。观察组患者在修复术前进行CT扫描断层图像,并应用3D技术按与实体1∶1大小打印患者骨盆模型,实行术前评估、规划及修复设计,对照组患者采取常规的骨盆骨折修复方式。分析骨盆骨折修复手术情况,定期复查骨折愈合和复位情况。结果观察组患者的术中出血量及术中输血量显著少于对照组,手术时间短于对照组,差异均有统计学意义(P<0.05)。观察组的术后并发症发生率(0),明显低于对照组(38.10%),差异有统计学意义(χ~2=9.882,P=0.002)。两组患者的复位优良率比较,差异无统计学意义(χ~2=1.273,P=0.259)。结论对于骨盆骨折修复患者进行术前评估、规划及修复,采取3D打印技术可明确骨折移位情况,便于手术的精准操作,有利于缩短手术时间及减少出血量、并发症等,3D打印技术可有效地对骨盆骨折修复术前评估、规划。Objective To investigate the value of 3 D printing technique in pelvic fracture repair.Methods From January 2015 to May 2016,42 patients with pelvic fracture were selected as the research object.The patients were divided into control group and observation group by random number table,with 21 cases in each group.The patients in the observation group underwent CT scan before repair,and the pelvis model was printed with 3 D technology according to the size of 1：1 with the entity.the preoperative evaluation,planning and repair design were carried out.The patients in the control group were treated with conventional pelvic fracture repair methods.The pelvic fracture repair surgery,regular review of fracture healing and reduction were analyzed.Results The amount of intraoperative blood loss and intraoperative blood transfusion in the observation group was significantly less than that in the control group,and the operation time was shorter than that in the control group,the differences were statistically significant（P〈0.05）.The incidence of postoperative complications in the observation group（0） was significantly lower than that in the control group（38.10%）,the difference was statistically significant（χ-2=9.882,P=0.002）.There was no significant difference in the excellent and good rate of reduction between the two groups（χ-2=1.273,P=0.259）.Conclusion For patients with pelvic fracture repair preoperative evaluation,planning and repair,3 D printing technology can be used to determine the displacement of the fracture,facilitate the precise operation of the operation,is conducive to shorten the operation time and reduce the amount of bleeding,complications,etc.,3 D printing technology can be effective for pelvic fracture repair preoperative evaluation and planning.
