Abstract: 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.
