Legg-Calvé-Perthes disease (LCPD); (1910)
LCPD develops as a result of proximal femoral epiphysis ischaemia of unknown aetiology; aka avascular necrosis (AVN) of the proximal femoral head.
The disease is usually insidious in onset and may occur after an injury to the hip. It is most common in male children aged 4-10 years, unilateral in 90% of cases. In cases which are bilateral, the joints are involved successively, not simultaneously.
In 1910, Legg, Calvé and Perthes independently reported a hip disease in children with a symptomatic picture resembling that described by Henning Waldenström in 1909. These authors believed the process to be unrelated to tuberculosis:
Arthur Thornton Legg: 5 cases between the ages of 5 and 8 years. Legg was most inclined to believe that the disease was caused by trauma because he had found such in all of his cases.
The fifth case (Dr. Goldwaith’s) was a boy of six, who came to him in December, 1908. One year previous he had a fall in which the legs were spread apart. He was lame for a week, and apparently recovered. Seven months later a limp on the left was noticed. He was restless at night and had indefinite pain referred chiefly to the left groin…
The Roentgenogram showed a flattened head and a distinct necrotic area just outside the epiphyseal line in the neck, with apparently some thickening of the neck…
…and at this time it seems to me that a possible explanation of the condition is that the injury may indirectly cause this condition by causing injury or displacement at the epiphyseal line, whereby the nutrition of the head, coming mostly through the neck, is impaired, and by the poorly nourished epiphysis bearing on the acetabulum, it becomes flattened.Legg A. 1910
