Spondylolisthesis grading system

A commonly adopted method of grading spondylolisthesis is the Meyerding classification, based on the ratio of [overhanging part of the superior vertebral body] to [anteroposterior length of the adjacent inferior vertebral body]: 

  • grade I: 0-25%
  • grade II: 26-50% 
  • grade III: 51-75% 
  • grade IV: 76-100%  
  • grade V (spondyloptosis): >100%
