In brief: Grading
Defined by how much the bone has shifted (translated) compared with the bone next to it.
Grade 1- 0-25% translation, 2-25-50% translation, 3-50-75% translation, 4-75-100% translation. Greater than 100% is called spondyloptosis.

In brief: Grade 1-4
The standard grading system most people use is how far the bone above is slipped off the bone below.
Grade 1 is 0-25%, grade 2 is 25-50%, grade 3 is 50-75% and grade 4 is 75-100%. If the bone is slipped all the way off it is called spondyloptysis.
