Assessment of spinal tumor treatment using implanted Three-Dimens

This study included 14 patients with spinal tumors from December 2017 to Jun 2018. Before surgery, all patients were subjected to CT scan and 3D data of the corresponding vertebral segments were collected. Titanium alloy formed 3D-printed vertebral body implantation and robotic stereotactic radiotherapy were performed for the reason of postoperative residual, high risk of recovery or recurrence after surgery. The main outcomes included the remission of symptoms, the vertebral body stability, the robotic stereotactic surgical precision and the local tumor control.
