What does limited scoliosis with spondylosis and facet arthropathy mean?

Degenerative change. If occuring in the lower back usually a small scoliosis has developed as a result of degenerating discs which also leads to facet joint degeneration- spondylosis means degenerative disc changes and facet arthropathy is a term for facet joint degeneration. Occasionally, a scoliosis present in the lower back alters the normal mechanics leading to these changes at an increased rate over normal.
See below. I suspect they mean mild scoliosis if they say "limited". Scoliosis is not necesarily a painful condition. Spondylosis and facet arthropathy are 2 fancy ways to say that there is some arthritis in the back.
