文题释义:
骨缺损:因创伤和手术所致的骨质短缺,称为骨缺损。由于骨缺损的存在,常造成骨不连接、延迟愈合或不愈合及局部功能障碍。临床上的骨缺损常是由于肿瘤、感染、创伤造成的。
增材制造技术:是融合了计算机辅助设计、材料加工与成型技术为一体的新型技术,可以通过软件将金属材料、非金属材料以及医用生物材料逐层打印出来,在骨缺损的临床应用方面有很大前景。
 
 
背景:增材制造技术凭借其能快速精准制备出假体的优点,在骨缺损治疗方面应用广泛。
目的:对增材制造技术在骨缺损方面的临床应用现状做一综述。
方法:由第一作者检索PubMed、CNKI、万方数据库2000至2018年收录的有关增材制造与骨缺损的文献,中文检索词为“骨缺损,增材制造,3D打印技术,骨肿瘤”,英文检索词为“Bone defect,Additive Manufacturing (AM),3D Printing,Bone tumour”。
结果与结论:①增材制造技术能结合现代影像技术,快速进行体外的假体三维重建;②治疗骨缺损时不仅能在术前构建骨缺损模型进行模拟手术,熟悉和对比手术方式,有效减少实际手术时间;还能快速精准的制备出形状各异的植入物,明显提高手术成功率;③增材制造技术展现出在骨缺损临床应用方面的优势。

Abstract:

BACKGROUND: Additive material manufacturing technology is widely used in the treatment of bone defects because of its advantages of rapid and accurate preparation of prostheses.
OBJECTIVE: To review the current situation of material addition technology applied in bone defects.
METHODS: The first author searched the articles related to additive manufacturing and bone defect repair in PubMed, CNKI, and WanFang databases published from 2000 to 2018. The keywords were “bone defect, additive manufacturing (AM), 3D printing, bone tumour” in Chinese and English, respectively.
RESULTS AND CONCLUSION: (1) The additive manufacturing technology can rapidly reconstruct the three-dimensional prosthesis in vitro with modern imaging technology. (2) In the treatment of bone defects, we cannot only establish the model of bone defects before operation to simulate the operation, familiarize and compare the operation methods, and effectively reduce the operation time, but also can quickly and accurately prepare different varieties of implants, significantly improving the success rate of surgery. (3) Additive manufacturing technology shows good prospects in the clinical application of bone defects.
