Intervertebral disc degeneration is believed to be the main cause of low back pain and has mostly been treated with lumbar interbody fusion or arthrodesis. Although fusion is a very common solution to low back pain it has been associated with disc degeneration and degenerative spondylolisthesis in the adjacent segment. A number of studies have been performed to study the effect of fusion, however there has not been any significant study to observe a fused spine with a degenerated disc at an adjacent level. This study involved a finite element model of the Lumbar spine L1-L5 which was fused with a bone graft at the L4-L5 level and degenerated in two stages at the L3-L4 level and also analyzed with reduced disc heights all in different cases.
