How this service works
Hevesi 2018 hip RAPID: sex (female 0, male 1) + Tonnis 0/1/2 (0, 2, 3 points; grade 3 invalid) + caller-assigned cam (1 if present). Max 5. Bands 0-1 low, 2-3 intermediate, 4-5 high. High-grade (ALAD 3-4) damage percent only at score 0 (10.5) and 5 (88.0). Not Rahman 2014 pleural RAPID. Not a diagnosis or operative plan. magent does not read radiographs or measure alpha angle.
Output
Returns the computed RAPID score (integer 0–5), the corresponding risk band (low 0–1, intermediate 2–3, high 4–5), and — where applicable at scores 0 and 5 — the published percent probability of high-grade (ALAD grade 3–4) acetabular labral and articular damage from the Hevesi 2018 derivation cohort.
Example use cases
Pre-arthroscopy labral damage risk stratification
“I have a female hip arthroscopy candidate with Tonnis grade 0 and no cam morphology — can you calculate her RAPID score and tell me if she's low, intermediate, or high risk for acetabular labral damage?”
High-risk male FAI patient scoring
“Run the Hevesi hip RAPID score for a male patient with Tonnis grade 2 and cam morphology present — I need the score, the risk band, and the high-grade ALAD damage probability if it applies.”
Comparing risk across Tonnis grades
“What's the RAPID score and risk band for a female patient with Tonnis grade 1 and no cam morphology? I want to see how it compares to a grade 2 case I'm evaluating.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rapid_hipWhen to prefer
Use this endpoint when you need to arithmetically apply the Hevesi 2018 hip RAPID scoring system to discrete, caller-assigned clinical variables (sex, Tonnis grade 0–2, cam morphology). It is not a diagnostic tool, does not interpret imaging, and should not be used for Rahman 2014 pleural RAPID or any other RAPID variant. Prefer this over manual calculation when building clinical workflow agents, pre-operative risk summaries, or decision support pipelines that already have Tonnis grade and cam morphology assessed by a clinician or radiologist.
Side effects
- Tonnis grade 3 supplied — invalid input, no grade 3 in derivation cohort, returns error
- Missing required parameter (sex, tonnis_grade, or cam_morphology) — 400 bad request
- tonnis_grade out of range (negative or >2) — validation error
- Payment not provided or insufficient — 402 Payment Required
- Incorrect type for cam_morphology (non-boolean) — schema validation error
