Perthes disease is a rare childhood hip disorder which affects children from the age group of four to ten years. The disease affects a child’s hip when blood supply is interrupted to the head of the femur (thigh bone) temporarily. Because of lack of blood supply to head the cells gradually start dying and results in deformed head. Over the period of time cells start regenerating and end with deformed head. Early diagnosis and timely intervention gives better results.

Early diagnosis and timely intervention gives better result. So any child during early age group with pain in and around hip and knee should be examined thoroughly by expert pediatric orthopedic surgeon. Normally, the younger children respond to the treatment more effectively without developing any hip joint disorder in the future. But if the child is more than 8 years of age, there are always chances that he may experience stiffness, arthritis, and similar hip joint problems in future.
