Get StartedTests and diagnosis
By Mayo Clinic staffDiagnosis of Legg-Calve-Perthes disease is often based on:
- Your child's signs and symptoms
- A physical exam
- Imaging studies
Your child's doctor may recommend X-rays, magnetic resonance imaging (MRI) or bone scans to detect changes in the bones. Sometimes Legg-Calve-Perthes disease is detected incidentally during an X-ray done for other reasons.
