Pert Health Dictionary

Whooping cough... pertussis

A condition of the hip in children, due to death and fragmentation of the epiphysis (or spongy extremity) of the head of the femur. The cause is not known. The disease occurs in the 4–10 year age-group, with a peak between the ages of six and eight; it is ten times more common in boys than girls, and is bilateral in 10 per cent of cases. The initial sign is a lurching gait with a limp, accompanied by pain. Treatment consists of limiting aggressive sporting activity which may cause intact overlying CARTILAGE to loosen. Where there are no mechanical symptoms and MRI scanning shows that the cartilage is intact, only minor activity modi?cation may be necesssary – but for several months or even years. Any breach in the cartilage is dealt with at ARTHROSCOPY by ?xing or trimming any loose ?aps. Eventually the disease burns itself out.... perthes’ disease

Inflammation of an epiphysis of the head of the femur.

The disease is a type of osteochondritis juvenilis, thought to be due to disrupted blood supply to the bone.

The condition is most common in boys aged 5–10, and usually affects 1 hip.

Symptoms include pain in the thigh and groin, and a limp on the affected side.

Diagnosis is made with X-rays.

Treatment may be rest for a few weeks, followed by splinting of the hip, or surgery.

The disease usually clears up by itself within 3 years, but the hip may be permanently deformed.... perthes’ disease

(Perthes disease, pseudocoxalgia) necrosis of the head of the femur (thigh bone) due to interruption of its blood supply (see osteochondritis). Of unknown cause, it occurs most commonly in boys between the ages of 5 and 10 and causes aching and a limp. The head of the femur can collapse and become deformed, resulting in a short leg and restricted hip movement. Affected boys are kept under observation and their activities are restricted; surgery may be required in more severe cases. [A. T. Legg (1874–1939), US surgeon; J.
