Legg–Calvé–Perthes disease (LCPD) is a disorder in children were the head of the femur dies due to a lack of blood flow (avascular necrosis).[1] The most common symptom is a gradual onset of a limp.[1] Ability to move the leg may be deceased.[1] Pain is variably present and may occur in the hip, knee, or bum.[1] Both side are affected in up to 15% of cases.[1] Complications may include osteoarthritis.[1]
The cause is unknown but it is believed to involved multiple factors.[1][2] Proposed risk factors include genetics, hyperactivity, blood clotting problems, exposure to cigarette smoke, and extreme motion at the hip.[1][2] Diagnosis is by X-rays after ruling out other causes of osteonecrosis of the femoral head.[1]
There is no cure.[1] Treatments may include NSAIDs, decreasing physical activity, and physical therapy.[1] If these measures are insufficient surgery may be recommended.[1] Outcomes are usually good.[2]
The condition affects 1 in 1,200 people (1 to 21 per 100,000 people per year).[1][3] Those between the ages of 4 and 8 years are most commonly affected, but it can start at 18 months until growth stops.[1] Males are more commonly affected.[1] The first detailed description was in 1910 by Arthur Legg, Jacques Calvé, and Georg Perthesin.[1][2]
