PLIF: Poterior Lumbar Interbody Fusion

PLIF is a procedure used to treat problems such as disc degeneration, disc herniation, and spine instability. In this procedure, the surgeon works on the spine from the back (the posterior) and removes a spinal disc in the lower (lumbar) spine. In this procedure, the surgeon works on the spine from the back (the posterior) and removes a spinal disc in the lower (lumbar) spine. The surgeon inserts bone graft material into the space between the two vertebrae where the disc was removed (the interbody space). The graft may be held in place with a special fusion cage. The goal of the procedure is to stimulate the vertebrae to grow together into one solid bone (known as a fusion). A fusion creates a rigid and immovable column of bone in the problem section of the spine.
