摘要
背景:脊柱侧凸是脊柱外科中常见的脊柱畸形疾病,常好发于许多儿童和青少年。严重的脊柱侧凸给患者带来身体与心理上的伤害,接受适当的手术治疗成为解决问题的有效方法。目的:文章综述了3D打印技术与有限元分析的研究背景及发展,总结并归纳了3D打印技术与有限元分析的广泛使用推动了脊柱外科矫形的发展。方法:以"Scoliosis,3D printing,finite element analysis"为英文检索词,应用计算机在PubMed数据库检索2000至2020年的相关文献共200篇;以"脊柱侧凸、3D打印、有限元分析"为中文检索词,应用计算机在知网数据库检索2000至2020年的相关文献共11篇。文章对3D打印技术与有限元分析应用于脊柱侧凸矫形研究的相关文献进行综述。结果与结论:文章最终纳入52篇进行综述分析。(1)3D打印技术可以有效结合有限元方法模拟脊柱矫形手术,以预测、分析植入物及相邻结构之间的应力变化,辅助医务人员进行术前规划并指导手术过程,减少术中出血及降低相应并发症的风险;(2)3D打印技术与有限元分析具有一定局限性,其成本价格相对昂贵,且还未形成完整的数据库,可能会为患者的治疗带来一定的影响;(3)总之,3D打印技术与有限元方法虽然有不足之处,但两者对于脊柱侧凸矫形具有重要的贡献,其在医学领域的发展前景值得期待。
BACKGROUND:Scoliosis is a common spinal deformity disease in spinal surgery,which often occurs in many children and adolescents.Severe scoliosis brings physical and psychological damage to patients,and receiving appropriate surgical treatment has become an effective way to solve the problem.OBJECTIVE:To review the research background and development of three-dimensional(3D)printing technology and finite element analysis,and summarize and conclude that the widespread use of 3D printing technology and finite element analysis has promoted the development of spinal orthopedics.METHODS:Using"Scoliosis,3D printing,finite element analysis"as the English search term,a computer was used to retrieve 200 related documents from 2000 to 2020 in the PubMed database;"Scoliosis,3D printing,finite element analysis"were used as Chinese search terms,a computer was used to retrieve 11 related documents from 2000 to 2020 in CNKI database.This paper reviews the related literature of 3D printing technology and finite element analysis applied to scoliosis correction research.RESULTS AND CONCLUSION:Finally,52 articles were included for review and analysis.(1)3D printing technology can effectively combine finite element methods to simulate spinal orthopedic surgery to predict and analyze the stress changes between implants and adjacent structures,assist medical staff in preoperative planning and guide the surgical process,and reduce intraoperative bleeding and reduce the risk of corresponding complications.(2)3D printing technology and finite element analysis have certain limitations;their cost is relatively expensive,and a complete database has not yet been formed,which may have a certain impact on the treatment of patients.(3)In short,although 3D printing technology and finite element method have shortcomings,they have important contributions to scoliosis correction,and their development prospects in the medical field are worth looking forward to.
