Legg-Calve-Perthes disease (LCPD) is a rare hip disease. It affects children 2-12 years old. LCPD is a disorder of the top of the leg bone. The disorder interrupts blood flow to the hip. The loss of flow causes death of bone and impairs bone growth. Over time, it causes deformity as the bone breaks and reforms causing the child to limp. LCPD most often occurs in just one hip.
The cause of LCPD is unknown. Infection, trauma, and inflammatory processes are possible causes.
LCPD is more common in male and at ages 4-8 years. It is also more common in children with European, Asian, or Eskimo ancestry. Other factors that may increase your child’s chance of developing LCPD include:

Medical treatment is used to improve healing and prevent further injury to the hip.
In some cases, your child may need surgery.
There are no known ways to prevent this rare disease.
