Unlike isthmic spondylolisthesis, the degree of the slip of a degenerative spondylolisthesis is typically not graded as it is almost always a grade 1 or 2 in cases of degenerative spondylolisthesis, the degenerated facet joints tend to increase in size, and enlarged facet joints then encroach upon the spinal canal that runs. In general, physicians use the meyerding grading system for classifying slips this is a relatively easy to understand system slips are graded on the basis of the percentage that one vertebral body has slipped forward over the vertebral body below thus a grade i slip indicates that 1-24% of the vertebral body has slipped.
