Legg-Calve-Perthes disease happens when the ball of the thighbone in the hip doesn’t get enough blood. This causes the bone to die. As a result, the bone may break easily, even without a major injury. These breaks take a long time to heal. The disease is also known as avascular necrosis of the hip. The cause of this disease is not known. It generally happens between ages 4 and 10. It most often affects boys.
The earliest sign of the disease is limping. There may also be pain or stiffness in the hip. One leg may be shorter than the other.
The earlier the disease is found, the better the outcome. However, if the problem develops after age 8, there may be long-term effects. These include deformity of the hip joint and osteoarthritis as an adult.
Your child’s treatment will vary based on the severity of the disease. The goals of treatment are to relieve symptoms, maintain hip motion, and keep the hip in the correct position. Treatment may include any of the following:
-
Over-the-counter pain medicines
-
Physical therapy
-
Crutches
-
Cast or brace
-
Surgery
Most children with the disease can return to normal activities within 2 years of treatment.
Home care
-
Limit activity as advised by your child’s health care provider. Initially, it's generally advised to not put weight on the affected leg.
-
You may use over-the-counter pain medicine to control pain, unless another medicine was prescribed. If your child has chronic liver or kidney disease or has ever had a stomach ulcer or gastrointestinal bleeding, talk with your health care provider before using these medicines.
Follow-up care
Follow up with your child's health care provider, or as advised.
When to get medical advice
Contact your child's health care provider if either of the following occur:
-
Sudden increase in hip pain with or without injury
-
Increased limping
