Perthes Disease (Legg-Calve-Perthes Disease)
Perthes disease is a rare childhood condition that affects the hip. It occurs when the blood supply to the head of the femur (thighbone) is disrupted. Without an adequate blood supply, the bone cells die, a process called avascular necrosis.
Although the term “disease” is still used, Perthes is a complex process of stages that last several years. As the condition progresses, the weakened bone of the head of the femur (the “ball” of the “ball-and-socket” joint of the hip) gradually begins to break apart. Over time, the blood supply to the head of the femur returns and the bone begins to grow back.
Treatment for Perthes focuses on helping the bone grow back into a rounded shape that fits into the socket of the hip joint, to allow smooth movement, and prevent hip problems in adulthood.
The long-term outcome for children with Perthes depends upon how round the ball and smooth the ball and socket joint is when the child stops growing. After 18 months to 2 years of treatment, most children return to daily activities without major limitations.
