Direct 3D Printed Titanium Alloy Spinal Implants

News 02,Sep,2021

Traditional Method

In the past, the surgery often uses titanium mesh to fill in autologous or allogeneic bone as an interbody support material. However, once the titanium mesh is displaced compressing the spinal cord, the patient is at risk of paralysis.

Solution

Establish a precise 3D model based on the CT scanned data. Design the surface of 3D polygonal structure and a mechanically optimized lattice structure inside. The spongy microporous structure combined with the topological frame structure facilitates the growth of bone cells, and finally achieves bone fusion, which has stronger bearing capacity than the conventional titanium mesh.

Workflow

Advantages:

The 3D printed artificial vertebral body is completely reconstructed and fixed according to the anatomy of the patient. After installing the precise and personalized artificial spine, the patient who was a truck driver recovers well and was able to drive a few months later.

Machine: Eplus3D Metal 3D Printer EP-M260 

Material: Titanium Alloy
