At what average age does Legg-Calvé-Perthes disease typically onset?

Legg-Calvé-Perthes disease typically has an onset around the age of 6 years old. This condition is a childhood hip disorder that occurs when blood supply to the femoral head is temporarily disrupted. As a result, the bone begins to die and can lead to issues with hip joint function. The average age for diagnosis often falls between 4 and 8 years, with the peak incidence occurring around 6 years old. This age range aligns with the typical developmental phase of children, where growth and physical activity levels might influence the condition's manifestation. Recognizing this average age is crucial for early diagnosis and intervention, which can help in managing the disorder effectively.
