Its degeneration causes lower back pain, which causes economiclosses due to treatment and absence from work. Finite element analysis has beenused for understanding the complex degeneration process. However, such studiesassumed the disc to behave linearly in the elastic region under static loading. In thiswork, nonlinear FE analysis was used to model the degeneration process asrealistically as possible. This was accomplished using an advanced FE capable ofsimulating the flow of bodily fluid through the living tissues of the disc. This allowedthe material properties to change according to time, load and deformation, whichoccurs in reality. Furthermore, an innovative approach – DOE – was applied toanalysis the effect of changing fluid permeability of the annulus fibrosus (AF) andnucleus pulposus (NP), which are the two main parts of the IVD. The analysisrevealed that permeability has a strong effect on the value of deformation of the IVDunder load. In addition, there is even a clear interaction effect between thepermeability of AF and NP on deformation.}, keywords = {lumbar spine,intervertebral,vertebrate,back pain,Finite Element}, url = {https://amme.journals.ekb.eg/article_35023.html}, eprint = {https://amme.journals.ekb.eg/article_35023_bd813906eecf179f51b0d578c976ce27.pdf} }
