title: Legg-Calvé-Perthes disease, protein C deficiency, and beta-thalassemia major: report of two cases.
abstract: Legg-Calvé-Perthes disease is an idiopathic osteonecrosis or avascular necrosis of the capital femoral epiphysis and the associated complications thereof occurring in an immature growing child. The association between osteonecrosis of the femoral head and thrombophilia was postulated by Glueck in 1994. We describe Legg-Calvé-Perthes disease associated with protein C deficiency and beta-thalassemia major in two children among a cohort of 79 beta-thalassemia patients treated in our clinic. The association of thrombophilia, aseptic necrosis of the femoral head, and beta-thalassemia has not been previously described in the literature.
