Clinical takeaway

Standing lateral lumbar radiograph (± flexion/extension).

When to use

Spine imaging: standing full-spine films, flexion/extension views, CT/MRI — scoliosis follow-up, adult deformity, stenosis reporting and surgical planning.

How it works

Slip percentage < 25%: Meyerding grade I Slip percentage 25–50%: grade II Slip percentage 50–75%: grade III (high-grade) Slip percentage 75–100%: grade IV Slip percentage > 100%: grade V (spondyloptosis)

Key points

  • Standing lateral lumbar radiograph (± flexion/extension).
  • Each value is graded against published reference ranges.
  • Measurement technique and positioning change the numbers — compare like with like on follow-up.
  • Part of the YuanDoctor MSK measurement topic.
