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

Legg-Calvé-Perthes disease typically presents in children between the ages of 2 and 10 years. This condition is characterized by avascular necrosis of the femoral head, which occurs due to a temporary loss of blood supply. The age range is significant because it highlights the vulnerability of the developing hip joint during early childhood when the bones are still growing and changing.

During this period, children may present with symptoms such as limping, hip or knee pain, and reduced range of motion. The disease is less common in infants and teenagers, which aligns with why the other age ranges provided in the question are not considered typical for onset. Consequently, understanding that Legg-Calvé-Perthes disease usually affects younger children helps in recognizing the importance of early diagnosis and management to prevent potential long-term complications, including osteoarthritis.
