Posterior Thoracolumbar Fusion

Posterior lumbar interbody fusion (PLIF) involves adding bone graft to an area of the spine to set up a biological response to promote bone growth between the two vertebral elements and thereby stop the motion at that segment. The PLIF achieves spinal fusion in the low back by inserting a cage made of either allograft bone or synthetic material (PEEK, PEKK or titanium) directly into the disc space.
