3D Printing in Spine Surgery.

Abstract

In the past 5 years, the application of 3D printing technology in the field of spine surgery had obtained enormous and substantial progress. Among which, vertebral skeleton model (including lesion model) printing has been widely used in clinical application due to its relatively simple technology and low cost. It shows practical value and becomes popular as the reference of clinical education, auxiliary diagnosis, communication between doctor and patient, and the planning of surgical approaches as well as the reference of more accurate operation in surgery. On the basis of vertebral skeleton model printing, it can be used to design and make navigation template to guide internal fixation screw, which also obtains some remarkable clinical effects. However, 3D printing technology has a more profound influence on spine surgery. The part with full expectation is undoubtedly the clinical application of 3D printing microporous metal implant and personalized implant as well as the clinical application of 3D printing biological materials in the future.
