Transforaminal lumbar interbody fusion (TLIF) is a surgical technique designed to stabilize the spinal vertebra and disc absorber among the spinal cord. Lumbar fusion is used to create solid bone among the open areas of the spinal cord to prevent any movement between the bones. TLIF surgery is approached from the back in where spinal hardware and pedicle screws/rods are used to hold the spine in place during the procedure. The bone graft substitute, either artificially made or taken from the pelvis area, is placed among the open-spaced area of the spine. The anterior and posterior columns of the spinal cord are then fused together in creating one long spinal connection and grafting is molded among the vertebrae.
