What is a Spinal Cage?

A spinal cage, also known as an interbody, is used in procedures that remove intervertebral discs from the spine. The spinal cage is placed in the disc space to help fuse the spine for stabilization and/or to restore lordosis, or curvature of the spine. The shape of the cage differs based on the procedure and location on the spine.

Spinal cages may be comprised of solid titanium, PEEK, allograft, or 3D printed titanium alloy. To learn more about different spinal cage materials, click here. ​
