Posterior Lumbar Interbody Fusion: With and Without Pedicle Screw Fixation
We are presently using posterior lumbar interbody fusion (PLIF)  for posterior decompression and simultaneous interbody fusion mainly in one or two segments in the lumbar and lumbosacral areas for selected intervertebral disk hernia cases, failed back cases, and various sorts of spondylolisthesis cases. Internal fixation with pedicle screw systems is also being conducted in selected cases so as to diminish pseudarthrosis, shorten postoperative bed rest, and reduce spondylolisthesis. In this paper we compare the results of simple PLIF and PLIF with pedicle screw fixation in order to investigate the differences between these two methods based on various parameters.
