Perthes Disease, also known as Legg-Calve Perthes Disease is a childhood disorder that affects the head of the femur bone, where it connects to the hip bone. Begins in childhood and affects boys more than girls between the ages 4-8 and is more common in Caucasian children than those of an ethnic back round. Usually it only affects one hip, but in 10% of some cases it affects both. This is not an infectious disease, so other children in the house won’t be affected.
It occurs when blood supply is temporarily cut off from the bone. The bone begins to die, a process that doctors call avascular necrosis, making the bone more susceptible to breaking and heals poorly.This causes the head of the femur to no longer be round, causing hip pain, limping, and little leg movement. The bone will begin the process of remodeling, but it won’t heal to back to its state of round and smooth. The hip joint may become flat. It can go through 4 phases.
The signs or symptoms that a child could have this disease is limping, pain or stiffness in the hip, groin, thigh, and or knee, and lastly limited movement in the hip joint. If a child is saying they have any of these they should have their doctor, take a look at it, but if he/she has a fever or can’t put any weight on that leg, then they should seek emergency medical help. It is still unknown for how or what causes this disease. Once a diagnosis is made, which is by a doctor listening to the symptoms. An x-ray is the ordered and that will confirm the diagnosis.
