Can someone explain this to me
 

I had two spinal fusions and a laminectomy The first one bone graft did not take. I just found out that I have spondolysis of cervical ,thorasic,lumbar spine. Many buldging disc throughout my spine.My biggest problem is in coccyx area I cant sit due to pain. I then had a mri done.Results as follows l3 l4 posterior facet hypertrophic changes are noted producing mild deformity of lateral recess.atl4 l5 of the residual disc material is noted with posterior facet hypertrophic change and spondylitic change.evidence of prior laminectomy is noted.the theal sac is quite capacious at this level.expected enhancement is noted within operative bed. At l5 s1 dorsal disc buldging is noted with ligamentum flavum thickening andposterior facet hypertrophic change. What is schmoris nodes noted adjacent to the l3 l4 disc alsoposterior facet hypertrophic changes are noted producing mild deformity of the lateral recess.
