Child Symptoms of Perthes Disease

Perthes disease is a condition where a temporary loss of blood supply to the hip causes the rounded head of the femur to die, leading to pain and restricted movement. This condition is most common in children between 4 and 10 years old, and is five times more common in boys, according to the American Academy of Orthopaedic Surgeons. However, girls typically experience a more severe condition if they do get Perthes disease.

Early Symptoms

Initially, the child may begin limping, either without pain or only mild pain. Pain often occurs first in the knee. These symptoms can come and go for several months.

Pain and Spasms

Other symptoms may include pain in the thigh or groin, and muscle spasms around the hip. Often the pain is relieved by resting, but begins again during activity.

Hip Stiffness

The child may experience hip stiffness that restricts movement, causes difficulty walking and results in a limited range of motion.

Later Symptoms

Eventually, there may be shortening of the affected leg, as well as muscle wasting in the upper thigh.

Treatment

Treatment can include anti-inflammatory medication and physical therapy. The child may need to use crutches or wear casts on a temporary basis, or might be prescribed bed rest in traction. The doctor may also advise surgery.
