3D打印技术骨科临床应用效应系统性综述

目的 评价3D打印技术骨科临床应用的效应。方法 通过系统性综述和Meta分析，比较3D打印技术与传统常规技术在骨科临床应用的效应。 结果 对25篇纳入的文献进行Meta分析显示，3D打印技术可减少骨科手术时间（26分钟左右），降低术中出血量（77毫升左右），提高植钉准确率或成功率（为传统常规技术的2.10倍），但未减少并发症发生率。结论 3D打印技术骨科临床应用的短期效应总体较好，但在我国骨科临床应用应谨慎发展。

Systematic Review of the Effects of Clinical Application of Three-dimensional Printing Technology in Orthopedics

Objective To assess the effects of clinical application of three-dimensional printing technology (3D printing) in orthopedics. Methods To compare the effects of clinical application of three-dimensional printing technology with traditional standardized technology, using a systematic review and Meta analyses. Results Meta analyses of 25 studies included in the research showed that application of 3Dprinting reduced operat ion time by 26 minutes , decreased intraoperative blood loss by 77 ml , and increased accuracy rate or success rate of screw implanting. Conclusion The application of 3D printing in orthopedics have good short-term effects. But its development in clinical application should be cautious.
