Abstract: | Various intervertebral spacers with or without posterior instrumentation use pedicle screw fixation in posterior lumbar interbody
fusion (PLIF). Recently we harvested an autologous cortical bone graft from a spinous process by en bloc resection and inserted
it between two intervertebral spacers during PLIF surgery. Due to better balance, this procedure provides greater mechanical
strength, larger contact area, and better bilateral restoration of disc height than PLIF using intervertebral spacers only,
and there is no need to take a bone graft from the iliac crest. This technique appears to result in effective spinal fusion
in PLIF surgery.
