Trans-sacral Interbody Fusion (AxiaLIF) is a surgical procedure in which the front part of the lumbar spine is fused from below. The surgeon makes an incision just above the tailbone. The trans-sacral fusion surgery applies only to the lower-most disc(s). Instruments are passed through a tube into the disc space. Disc material is removed, and a fusion graft is placed into the disc space. The graft is usually a screw-like cage combined with bone.
