This is where 3D printing becomes far more than a manufacturing trick. It can create an implant shaped specifically around the anatomy of one individual patient.
For some spinal cancers, surgeons must remove an entire vertebra, or even several vertebrae, to take out the tumor. That leaves a major structural gap in the spine. Chinese surgical teams have been using patient-specific titanium artificial vertebrae, designed from CT scans, to reconstruct these missing sections.
The clever part is the implant’s microscopic structure. Instead of being a completely solid block of metal, sections can be printed with thousands of interconnected pores that imitate the architecture of spongy bone. These surfaces give the patient’s own bone somewhere to grow, helping the implant gradually become biologically integrated with the surrounding spine.
In one Chinese series involving complex multi-level spinal tumors, six patients successfully received customized 3D-printed titanium vertebrae. Follow-up imaging showed bone growing into the porous implant interface, and the successfully implanted patients were moving freely without pain at a median follow-up of 11.5 months.
A 2026 systematic review has since examined the broader evidence for 3D-printed artificial vertebral bodies after spinal tumor removal, showing how this technology is moving from remarkable individual operations toward a more established method of spinal reconstruction.
The idea sounds almost science fiction: remove a cancer-damaged part of the skeleton, digitally design a replacement for that exact patient, print it from titanium, and create its surface so living bone can eventually grow into it.
