Posterior Lumbar Interbody Fusion (PLIF) is a surgical technique that attempts to eliminate instability in the back and pain in the lower back and lower extremities. A Maximum Access Surgery Posterior Lumbar Interbody Fusion (MAS PLIF) achieves this by using a less disruptive approach to decompress nerve roots and fuse one or more vertebrae together to reduce their motion.
The distinct difference between a traditional “open” PLIF and a MAS PLIF is the medialized surgical approach. The MAS PLIF procedure is designed to eliminate the need to retract muscle laterally, therefore requiring a smaller incision than an “open” PLIF. By minimizing the amount of muscle disruption, this procedure is intended to reduce postoperative approach-related muscle pain and enable a faster recovery for the patient.
