打印技术辅助后路截骨治疗脊柱畸形的分析(6)

结果与结论：①共纳入6 篇文献，282 例患者，其中3D 打印组139 例，常规组143 例；②Meta 分析结果显示，3D 打印组在手术时间、手术出血量及手术放射暴露时间方面均小于常规组(P＜0.05)；③在Cobb 角、Cobb 角矫正率、置钉准确率及Oswestry 功能障碍指数评分方面均优于常规组(P＜0.05)；④3D 打印组和常规组在并发症方面差异无显著性意义(P＞0.05)；⑤上述数据证实，3D 打印辅助后路截骨能够明显降低手术间和手术出血量，改善手术效果。

BACKGROUND:3D printing technology was more and more widely used in spine surgery，and it had a good auxiliary surgery ，there is currently no evidence-based medical evidence to confirm the efficacy and safety of 3D printing-assisted posterior osteotomy for spinal deformities.

OBJECTIVE:To systematically evaluate the efficacy of 3D printing-assisted posterior osteotomy in the treatment of spinal deformity.

METHODS:Such databases as PubMed，Embase，Cochrane Library，CNKI，Wanfang，VIP，and CBM were searched from their inception to December 2019 for the research investigating 3D printing in the treatment of spinal and Chinese search terms were “3D printing”，“rapid prototyping”，“spinal deformity”.Literature review，data extraction，and quality evaluation were performed independently by two meta-analyses were performed using the RevMan 5.3 software.

RESULTS AND CONCLUSION:(1) Six literatures involving 282 patients were were 139 cases in the 3D printing group and 143 cases in the conventional group.(2) Meta-analysis results showed that in the 3D printing group，the operation time and surgical radiation exposure time were shorter，and intraoperative blood loss was less than in the conventional group (P＜0.05).(3) Cobb angle，Cobb angle correction rate，screw placement accuracy，and Oswestry disability index were all superior to the conventional group (P＜0.05).(4) In terms of complications，the difference was not statistically significant between the 3D printing group and conventional group (P＞0.05).(5) Above data verified that 3D printing-assisted posterior osteotomy can significantly reduce operation time and intraoperative blood loss and improve the surgical effect.
