[Effects of posterior lumbar spinal fusion on the stability of unstable lumbar segment and biomechanical properties of adjacent segments: a finite element study].
To explore the effects of posterolateral lumbar fusion (PLF) and posterior lumbar interbody fusion (PLIF) on the stability of postoperative unstable single lumbar segment and the biomechanical alterations of the adjacent segments. ⋯ Lumbar segmental stability after posterior laminectomy and facetectomy can be recovered by both PLF and PLIF. Both PLF and PLIF may increase the possibility of adjacent segment degeneration because of the augmentation of maximum stress on adjacent discs.
