Each vertebrae has a thick drum-shaped area in front called a vertebral body. Between the vertebrae are spaces that allow nerves (nerve roots) to go from the spinal cord to other parts of the body.

In anterolisthesis, the upper vertebral body is positioned abnormally compared to the vertebral body below it. More specifically, the upper vertebral body slips forward on the one below.

The amount of slippage is graded on a scale from 1 to 4. Grade 1 is mild (20% slippage), while grade 4 is severe (100% slippage).
 
How is this different from spondyliolithesis? This is all very confusing. Thanks
 
Spondylolisthesis is the overall term - meaning the displacement of one vertebra over another. There are two types, depending on whether the displacement is forward (anterolisthesis) or backward (retrolisthesis).

I hope this helps
 
Did surgery solve your problems with your grade 1 anterolisthesis of L5 on S1? Or did you have other back problems after surgery? Would you recommend surgery for other people or not?
 
Surgery is not usually indicated with a grade 1 spondylolisthesis, forward or backward. However, a study was recently concluded testing the efficacy of doing surgery on grade 1's and the future of the spine....will it get worse anyhow or will it stabilize and prevent further problems. The results are still not out. I missed the date for signing up for the study by 1 week(shoot!).

Maybe when the results are known, we will know if it's worth operating and fixing those problems.....I only wish I could have been part of it and gotten mine fixed.

PS...good explanation SpineAZ.
