摘要:


文题释义:

3D打印技术:是一种快速成型技术,以数字模型文件为基础,使用粉末状塑料或金属等可黏合材料,经逐层堆叠累积方式构造物体,用于骨盆骨折术前指导中,便于手术医师充分考虑术中可能存在的风险,提出更完善的手术计划,并在实物模型上反复练习,预测术中风险与手术疗效。
Majeed骨盆功能评分系统:是一种临床常用的骨盆功能评分系统,包括疼痛、工作、坐立、性生活和站立项目,包含广泛,实用性强,评分越高功能越好。

背景:骨盆骨折是严重骨折类型,单纯多层螺旋CT三维影像显示效果存在二维平面局限性,在骨盆骨折术前方案指导上存在不足。
目的:分析多层螺旋CT联合3D打印进行术前指导应用于旋转不稳定性骨盆骨折的临床效果。
方法:纳入2017年1月至2020年12月喀什地区第一人民医院收治的90例旋转不稳定性骨盆骨折患者,按随机数字表法分组,研究组(n=47)进行切开复位内固定前采用多层螺旋CT联合3D打印进行术前指导,对照组(n=43)进行切开复位内固定前采用多层螺旋CT进行术前指导。术后随访1年,记录两组骨折愈合时间,评估骨盆复位质量,参考Majeed骨盆量化评分标准评价术后骨盆功能恢复结果,以及术后不良事件发生率。
结果与结论:①研究组螺钉错位率低于对照组(P < 0.05),骨折愈合时间短于对照组(P < 0.05),术后3个月的骨盆骨折复位质量优良率高于对照组(P < 0.05);②与术后3个月比较,两组术后6,12个月的骨盆功能评分升高(P < 0.05),两组间术后3,6,12个月的骨盆功能评分比较差异无显著性意义(P > 0.05);③研究组47例中,发生骨折移位1例、创伤性关节炎2例,不良事件发生率为6%;对照组43例中,发生畸形愈合1例、异位骨化1例、骨折移位2例、创伤性关节炎2例、骨盆不稳2例,不良事件发生率为19%;两组间不良事件发生率比较差异无显著性意义(P > 0.05);④结果表明,对于旋转不稳定性骨盆骨折,相较于单纯采用多层螺旋CT进行术前指导,采用多层螺旋CT联合3D打印进行术前指导可提升骨折复位质量、缩短骨折愈合时间及降低螺钉错位率。

Abstract: BACKGROUND: Pelvic fractures are a serious type of fracture, and there are limitations in the two-dimensional plane display effect of pure multi-slice spiral CT three-dimensional images, and there is a lack of preoperative planning guidance for pelvic fractures.  
OBJECTIVE: To analyze clinical effect of multi-slice spiral CT combined with 3D printing in patients with rotationally unstable pelvic fractures.
METHODS: From January 2017 to December 2020, clinical data of 90 patients with rotationally unstable pelvic fractures admitted to the First People’s Hospital of Kashgar were included. They were grouped according to the random number table method. In the study group, 47 patients underwent multi-slice spiral CT combined with 3D printing technology to guide the operation. In the control group, 43 patients used multi-slice spiral CT for preoperative guidance before open reduction and internal fixation. After 1 year of follow-up, the fracture healing time of the two groups was recorded to evaluate the quality of pelvic reduction. The pelvic function recovery results were evaluated with reference to the Majeed pelvic quantitative scoring standard. The postoperative adverse event rate in the two groups was calculated.  
RESULTS AND CONCLUSION: (1) The screw dislocation rate in the study group was lower than that in the control group (P < 0.05), and the fracture healing time was shorter than that in the control group (P < 0.05). The excellent and good rate of pelvic fracture reduction 3 months after operation was higher in the study group than that of the control group (P < 0.05). (2) Compared with 3 months after operation, the pelvic function scores of the two groups at 6 and 12 months after operation were higher (P < 0.05). There was no significant difference in pelvic function scores between the two groups at 3, 6, and 12 months after operation (P > 0.05). (3) Among the 47 cases in the study group, 1 case of fracture displacement and 2 cases of traumatic arthritis occurred, and the incidence of adverse events was 6%. Among the 43 cases in the control group, malunion occurred in 1 case, heterotopic ossification in 1 case, fracture displacement in 2 cases, traumatic arthritis in 2 cases, and pelvic instability in 2 cases, with an adverse event rate of 19%. There was no significant difference in the adverse event rate between the two groups (P > 0.05). (4) It is suggested that for rotationally unstable pelvic fractures, compared with multi-slice spiral CT alone, the use of multi-slice spiral CT combined with 3D printing technology in the guidance of the surgical plan can improve the quality of fracture reduction, shorten the fracture healing time and reduce the screw dislocation rate.
