[Recurrent Perthes disease in a 6-year-old boy]. / Rezidiv eines M. Perthes bei einem 6-jährigen Jungen.

Two episodes of avascular necrosis in the same femoral capital epiphysis have been reported in Gaucher's disease and in six cases of Legg-Calvé-Perthes disease. The present case report is an additional example of a recurrent avascular necrosis in a six years old boy two years after complete healing of the first occurrence had been documented clinically and radiologically.
