Ligament Preservation

The spinal ligaments help stabilize the spinal column when in motion, which is why it is important to preserve the supporting ligamentous structures as much as possible during surgery. Most spinous process plates require removal of both the interspinous ligament and the supraspinous ligament for proper implantation.

The PercLIF surgical technique preserves the supraspinous ligament and only partially removes the interspinous ligament.
