    This study aimed to investigate the effect of transforaminal lumbar interbody fasion (TLIF) with bilateral pedicle screw fixation
    (BPSF) on dynamic responses of the adjacent spinal segments to whole body vibration (WBV) after nucleotomy. A previously validated
    finite element model of an intact Li -sacrum lumbar spine was modified to simulate nucleotomy with and without TLIF and BPSF
    at L4-L5. Transit dynamic analyses were conducted on the nucleotomy alone and the fasion models under a vertical vibration load
    The computed dynamic responses for the two models at adjacent levels were recorded and compared The results showed that at level
    (L5-SJ) below the denucleated disc, maximum response values of the disc bulge, annulus stress and intradiscal pressure decreased
    due to thefasion by 5.6%, 5.2% and 7.2%, and their vibration amplitudes decreased by 30.5%, 25.7% and 24.3%. At levels (LJ-L2,
    L2-L3 and L3-L4) above the denucleated disc, maximum response values and vibration amplitudes of the strains and stresses also
    produced 5.2-8.9% and 25.9-29. 7% deceases due to the fasion. It implies that after nucleotomy, application of the TLIF with BPSF
    might be helpfal to prevent negative effects of the vertical WBV on adjacent disc levels.
