What is the general age range for diagnosis of Legg-Calvé-Perthes disease?

Legg-Calvé-Perthes disease is typically diagnosed in children between the ages of 2 and 13 years. This condition primarily affects the hip joint, and its onset usually occurs in early childhood, with the most common ages ranging between 4 and 8 years.

The physiological processes underlying Legg-Calvé-Perthes disease involve a temporary loss of blood supply to the femoral head, leading to avascular necrosis. Since this condition arises during a period of rapid growth and development, particularly in young children, the age range of 2 to 13 years is fitting. It allows for an understanding of how the disease can progress during developmental stages and emphasizes the importance of early diagnosis and management to prevent long-term complications such as osteoarthritis or hip deformity later in life.

Understanding this age range is crucial for physical therapists, pediatricians, and parents, as it aids in recognizing symptoms and seeking timely intervention for a condition that can significantly impact a child's mobility and overall quality of life.
