Hip Pain

 

Legg-Calve-Perthes disease

Legg-Calve Perthes disease is a childhood condition in the hip where there is reduced blood supply to the ball portion of the thighbone in the hip (femoral head).
Without efficient blood supply to the bone, the bone can begin to weaken and loose its shape. As a result, the femoral head is no longer round and does not move efficiently in the hip socket. This can lead to hip pain, limping, and restricted leg movement.
Eventually the bone begins to heal itself through the natural process of bone remodeling. This process includes the old bone being removed and new bone is created to replace it. This cycle of breakdown and healing can occur several times

Causes/risk factors:

As mentioned above Legg-Calve-Perthes disease occurs when there is reduced blood supply to the ball portion of the hip joint (femoral head). The underlying causes of what causes the disruption of blood supply to the femoral head is still unknown. Risk factors can include:
* Age- between 4 and 8
* Sex- 5x more common in boys than girls
* Genetic mutation- in some cases Legg-Calve-Perthes disease can be linked to certain genetic mutation.
Signs & symptoms:
* Pain in the hip, groin, thigh or knee
* Limping
* Limited range of motion in the hip
* Legs appear to be different lengths
* Upper thigh muscle gets smaller
* Commonly occurs in only one hip. In some cases both can be affected.
Treatment:
* Imaging to confirm diagnosis
* Referral to orthopedic surgeon
* Casting/braces
* Activity modification
* Stretching exercises to loosen muscles and allow the hip to be more flexible.
* Surgery
