The purpose of this study was to compare the initial stiffness of two techniques for posterior interbody lumbar fusion (
PLIF
) by a finite element approach. Thus a finite element model of a human L3/4 spinal segment was generated.
Stiffness
of the intact model was tested under compression (600 N), torsion (25 Nm) and shearing forces (250 N) without preload. The results were compared to the stiffness following simulation of
PLIF
with two BAK-Cages and
PLIF
with two Harms-Cages and additional posterior screw-rod-osteosynthesis.
PLIF
with two BAK-Cages resulted in a loss of stiffness in compression, torsion and shearing.
PLIF
with two Harms-Cages and posterior osteosynthesis resulted in an increase of stiffness in compression, torsion and shearing.
