Three-dimensional printing has evolved into a cost-effective and accessible tool. In orthopedic surgery, creating patient-specific anatomical models and instrumentation improves visualization and surgical accuracy. In pediatric orthopedics, three-dimensional printing reduces operating time, radiation exposure, and blood loss by enhancing surgical efficacy. This review compares outcomes of three-dimensional printing-assisted surgeries with conventional surgeries for upper and lower extremity pediatric surgeries.
A complete search of medical literature up to August 2023, using Ovid Medline, EMBASE, Scopus, Web of Science, and Cochrane Library was conducted in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Broad search terms included "pediatrics," "orthopedic," and "3D-printing." Eligible studies were assessed for intraoperative time, blood loss, and fluoroscopy exposure.
Out of 3299 initially identified articles, 14 articles met inclusion criteria. These studies included 409 pediatric patients, with ages averaging 9.51 years. The majority were retrospective studies (nine), with four prospective and one experimental study. Studies primarily utilized three-dimensional printing for navigation templates and implants. Results showed significant reductions in operative time, blood loss, and radiation exposure with three-dimensional printing. Complication occurrences were generally lower in three-dimensional printing surgeries, but there was no statistical significance.
Three-dimensional printing is an emerging technology in the field of orthopedics, and it is primarily used for preoperative planning. For pediatric upper and lower extremity surgeries, three-dimensional printing leads to decreased operating room time, decreased intraoperative blood loss, and reduced radiation exposure. Other uses for three-dimensional printing include education, patient communication, the creation of patient-specific instrumentation and implants.

三维打印已发展成为一种经济高效且易于使用的工具。在骨科手术中，创建针对患者的解剖模型和器械可改善可视化效果并提高手术准确性。在小儿骨科中，三维打印通过提高手术效果减少了手术时间、辐射暴露和失血量。本综述比较了三维打印辅助手术与传统手术在小儿上下肢手术中的效果。
按照系统评价和Meta分析的首选报告项目指南，使用Ovid Medline、EMBASE、Scopus、Web of Science和Cochrane图书馆对截至2023年8月的医学文献进行了全面检索。广泛的检索词包括“儿科”、“骨科”和“3D打印”。对符合条件的研究评估其术中时间、失血量和透视暴露情况。
在最初识别的3299篇文章中，有14篇符合纳入标准。这些研究包括409名儿科患者，平均年龄为9.51岁。大多数是回顾性研究（9项），4项前瞻性研究和1项实验性研究。研究主要将三维打印用于导航模板和植入物。结果显示，三维打印可显著减少手术时间、失血量和辐射暴露。三维打印手术中的并发症发生率通常较低，但无统计学意义。
三维打印是骨科领域的一项新兴技术，主要用于术前规划。对于小儿上下肢手术，三维打印可减少手术室时间、减少术中失血量并减少辐射暴露。三维打印的其他用途包括教育、患者沟通、创建针对患者的器械和植入物。
