Clinical takeaway

Weight-bearing AP foot.

When to use

Foot & ankle imaging: weight-bearing foot and lateral calcaneal views — hallux valgus, flatfoot and calcaneal fracture assessment.

How it works

Hallux valgus angle < 15°: normal Hallux valgus angle 15–20°: mild Hallux valgus angle 20–40°: moderate Hallux valgus angle > 40°: severe Intermetatarsal angle < 9°: normal Intermetatarsal angle 9–11°: mild Intermetatarsal angle 11–16°: moderate (often proximal osteotomy) Intermetatarsal angle ≥ 16°: severe (proximal osteotomy or Lapidus) DMAA ≤ 10°: normal DMAA > 10°: lateral articular tilt (biplanar / distal correction)

Key points

  • Weight-bearing AP foot.
  • 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.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

FAQ

Frequently asked questions

What are the limits and cautions when using Hallux Valgus Measurements (HVA / IMA / DMAA / Sesamoid Position)?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Hallux Valgus Measurements (HVA / IMA / DMAA / Sesamoid Position) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Hallux Valgus Measurements (HVA / IMA / DMAA / Sesamoid Position) calculated in practice? Can you show a worked example?
Inputs: Sesamoid position (Hardy-Clapham) 4, Hallux valgus angle 32 °, Intermetatarsal angle 14 °, DMAA 8 ° → Result: Hallux valgus angle 32 °（Hallux valgus angle: 32 ° → 20–40°: moderate, Intermetatarsal angle: 14 ° → 11–16°: moderate (often proximal osteotomy), DMAA: 8 ° → ≤ 10°: normal）
