Meyerding grade (1932): percent anterior slip = (anterior displacement / caudal-endplate AP width) x 100; grades I-V by 25% bands.

Example
- Anterior displacement
- 14 mm
- Caudal-endplate AP width
- 40 mm
Result: Meyerding grade II — 35% anterior slip.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- I-II (1-50%)
- Low-grade spondylolisthesis.
- III-V (> 50%)
- High-grade (III 51-75%, IV 76-100%, V > 100% spondyloptosis). A radiographic grade, not a diagnosis.
What you enter
- Anterior displacement
- Caudal-endplate AP width
