What Is Spondylolisthesis?
I. Definition
The word spondylolisthesis derives from two parts - spondylo which means spine, and listhesis which means slippage. So, a spondylolisthesis is a forward slip of one vertebra (i.e., one of the 33 bones of the spinal column) relative to another. Spondylolisthesis usually occurs towards the base of your spine in the lumbar area.
II. Description
Spondylolisthesis can be described according to its degree of severity. One commonly used description grades spondylolisthesis, with grade 1 being least advanced, and grade 5 being most advanced. The spondylolisthesis is graded by measuring how much of a vertebral body has slipped forward over the body beneath it.
