A Screening Method for Dangerous Models of 3D Printed Bionic Artificial Vertebral Bodies - Finite Element Analysis

Spinal tumors can occur in or around the spine and may cause defects in the anterior column of the vertebral body, spinal instability, nerve and spinal cord damage, and other symptoms. Benefiting from the rapid development of spinal internal fixation and reconstruction instruments, total spine en bloc resection is gradually being accepted by more and more spinal surgeons. In recent years, with the increasing maturity of 3D printing technology, 3D printing artificial vertebral bodies have been used clinically to reconstruct the spine. In this study, a reliable 3D printed artificial vertebral body screening program is provided, and the finite element analysis results are used to improve the artificial vertebral body design to save expensive economic and time costs.KeywordsFinite element analysisBionic artificial vertebral bodySpinal tumors3D printedCervical body prosthesis
