Abstract EN
The present study was conducted to examine the effects of body weight on intradiscal pressure (IDP) and annulus stress of intervertebral discs at lumbar spine.
Three-dimensional finite element model of osseoligamentous lumbar spine was developed subjected to follower load of 500 N, 800 N, and 1200 N which represent the loads for individuals who are normal and overweight with the pure moments at 7.5 Nm in flexion and extension motions.
It was observed that the maximum IDP was 1.26 MPa at L1-L2 vertebral segment.
However, the highest increment of IDP was found at L4-L5 segment where the IDP was increased to 30% in flexion and it was more severe at extension motion reaching to 80%.
Furthermore, the maximum annulus stress also occurred at the L1-L2 segment with 3.9 MPa in extension motion.
However, the highest increment was also found at L4-L5 where the annulus stress increased to 17% in extension motion.
Based on these results, the increase of physiological loading could be an important factor to the increment of intradiscal pressure and annulus fibrosis stress at all intervertebral discs at the lumbar spine which may lead to early intervertebral disc damage.
