Legg–Calvé–Perthes disease is a childhood hip disorder that occurs when the blood supply to the head of the femur gets disrupted and leads to death or necrosis of the tissue.
The disease was named after three doctors; Arthur Legg, Jacques Calvé, and Georg Perthes.
This gives the hip joint the ability to move nearly in all directions, as long as the ball can smoothly rotate inside the socket.
In Legg–Calvé–Perthes disease, for some children, the blood supply to the femoral head becomes interrupted for some reason - and it’s not known why exactly.
The result is that the tissue begins to die off - a process called avascular necrosis.
Over time, there’s new blood vessel formation into the necrotized bone and that allows the dead tissue to get removed by immune cells called macrophages.
That process causes the head of the femur to lose mass, leaving it weak and prone to fractures.
Now, over time, Legg–Calvé–Perthes disease typically self-resolves and the bone is able to heal - once again it’s not known exactly why or how this happens.
Legg �Calv� �Perthes disease (LCPD) refers to a childhood hip disorder that occurs when the blood supply to the head of femur is disrupted for unknown reasons, resulting in avascular necrosis of the head of femur. The disease was named after three doctors; Arthur Legg, Jacques Calv�, and Georg Perthes. Children with LCPD develop hip limping and pain which worsens with activity, and it may be referred to the knee. The condition is often treated with surgery and physiotherapy to help restore movement and function.
