What Is PLIF?
PLIF surgery is a form of spinal fusion that treats lower back pain and leg pain that occurs when the round discs that separate your vertebrae wear out or are damaged. During a PLIF procedure, a surgeon removes the worn-out or damaged disk in your lower spine and replaces it with interbody spacers made from bone, plastic or metal.
Posterior lumbar interbody fusion has advantages and disadvantages. With PLIF, surgeons can achieve a 360-degree spinal fusion with a single incision. With one incision, surgeons insert interbody spacers into the front of the spine — this area has a high fusion rate as there is more surface area. One of the drawbacks of PLIF is that prolonged muscle retraction could delay recovery.
