Legg-Calve-Perthes disease is a rare bone disorder in children that causes the femoral head component (ball part) of the hip joint to lose blood supply.
This soft bone eventually fractures and loses its spherical form. The ball regains blood flow once the body has enough of it. However, if the ball does not regain its roundness after healing, it might cause discomfort and stiffness. The entire process of bone death, fracture, and regeneration might take many years.
Doctors employ a variety of treatments to keep the ball portion of the joint as spherical as possible. The socket serves as a mold for the fractured femoral head while it heals.
Signs and symptoms of Legg-Calve-Perthes disease include:
Legg-Calve-Perthes disease usually involves just one hip. Both hips are affected in some children, usually at different times.
