Management of Perthes' disease Benjamin Joseph ABstrAct The main complication of Perthes' disease is femoral head deformation. Evidence from the literature highlights two important factors related to the cause and timing of this complication.(1) Extrusion of the femoral head appears to be a major factor that leads to femoral head deformation. Perthes disease, also called Legg-Calvé-Perthes disease, is a rare condition of the hip that affects only children. It develops when there is a temporary loss of blood supply to the rounded head of the femur (thigh bone) - the "ball" part of the "ball and socket" hip joint. Blood supply is important for bone, as it delivers oxygen Legg-Calve-Perthes disease usually occurs between the ages of 3 to 12 years old, with the highest rate of occurrence at 5 to 7 years. It affects 1 in 1200 children under the age of 15. Legg-Calve-Perthes disease occurs most commonly in male patients, with a male to female ratio between 4:1 and 5:1. It is bilateral in 10% to 20% of affected cases. Perthes disease is also known as Legg-Calve-Perthes, named after the three doctors who first described the condition. It typically occurs in children aged 4 to 10 years. It is five times more common in boys than in girls. In 10% to 15% of all cases, both hips are affected. In the first stage of Perthes disease, the bone in the head of the femur Perthes disease (Legg-Calvé-Perthes disease) is a relatively common disease of the hip in childhood, affecting 10.8 of every 100 000 children. Its cause and treatment are still topics of controversy. The disease was described nearly simultaneously in the year 1910 by G. C. Perthes in Germany, A. T. Legg in the United States, and J.
