Risk factorsBy Mayo Clinic staff
Risk factors for Legg-Calve-Perthes disease include:
- Age. Although Legg-Calve-Perthes disease can affect children of nearly any age, it most commonly occurs between ages 4 and 8.
- Your child's sex. Legg-Calve-Perthes is up to five times more common in boys than in girls.
- Race. White children are more likely to develop the disorder than are black children.
- Family history. In a small number of cases, Legg-Calve-Perthes appears to run in families.
