Lumbar – Transforaminal Lumbar Interbody Fusion (TLIF)

1 Transforaminal Lumbar Interbody Fusion (TLIF) A Transforaminal Lumbar interbodyfusion ( tlif ) is performed toremove a portion of a disc that isthe source of back or leg pain. Likethe PLIF (posterior lumbarinterbody Fusion ) procedure, bonegraft is used to fuse the spinalvertebrae after the disc is , the tlif procedureplaces a single bone graft betweenthe vertebrae from the side, ratherthan two bone grafts from the rearas in the PLIF procedure. Insertingthe graft from the side where thefacet joint has been removed is aneffort to avoid moving or damagingnerve roots during the content is for informational purposes only.

3 Inserting the graft from the sidewhere the facet joint has been removed is an effort to avoidmoving or damaging nerve roots during the incision is made in the middle of the low back. Surgicalinstruments are used to remove the entire facet joint on one side inorder to allow access to the degenerated disc. A graspinginstrument is used to remove most of the intervertebral the facet joint and disc relieves pressure on thecompressed spinal nerve, allowing it to return to the PlacementA single bone graft is placed in the disc space from the lateral(side) aspect through the area exposed when the facet joint wasremoved.

4 The bone graft will provide stability to the spine when itfuses with the vertebrae above and below it. In variations of thisprocedure, spacers, cages packed with graft material, or groundbone graft material may also be packed into the disc space to aidwith the content is for informational purposes only.

A drill is used to make holes in the pedicle areaof the vertebrae, and screws are placed in the drilled holes.

6 Next,rods are positioned between the screws and fastened in rod and screw instrumentation provides stability to the spineand prevents the vertebrae from moving while the bone graftfusion takes GraftBone grafting can be done with pieces of a patient s own bone(autograft), processed bone from a bone bank (allograft), or a bonegraft substitute (demineralized bone, ceramic extender, or bonemorphogenetic protein). To harvest a patient s own bone forgrafting, a second incision is made over the back of the is removed from the iliac crest and placed along theprepared site where the top layer of bone was removed.
