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.
