Coagulation parameters were studied in a population of 118 children with Perthes disease in order to determine the possible role of thrombophilia as a causative factor for the disease and to determine if thrombophilia could affect its course. We found 27 children presenting one or more coagulation disorders. The statistical analysis concurs with previous findings of a relationship between Legg-...

Osteochondral lesions most commonly occur about the knee but may affect any articular surface of the pediatric appendicular skeleton. Osteochondral lesions include osteochondritis dissecans, osteochondral fractures, and osteochondral abnormalities associated with secondary processes such as Legg-Calvé-Perthes disease. These abnormalities should not be confused with normal subchondral irregulari...

Osteopetrosis is a rare inherited disorder of bone causing increased bone density. Legg-Calvé-Perthes disease (LCPD), by contrast, is a more common idiopathic condition leading to variable avascular necrosis of the immature femoral head. We present a case of a 5-year-old boy presenting with these co-morbidities. We have found only one previous reference suggesting these two conditions can coexi...

OBJECTIVE The aim of this study was to determine the intra and interobserver concordance rates of the Waldenström, Catterall and Herring classifications for Legg-Calvé-Perthes disease. METHODS One hundred radiographs of the pelvis in anteroposterior and Lauenstein views, from patients with this disease, were selected. The radiographs were classified by four physicians with different levels of...

About a hundred years after the first reports about the disease Legg-Calvé-Perthes that Perthes also called, since it is still the main cause of this disease is unknown. Perthes with the loss of femoral head blood flow in growing children, between the ages of 2-13 years is determined and is considered as a vascular disease. The outbreak, one in every 1,200 children younger than 15 years is. 5-4...

This paper discusses the differential diagnosis of unusual and distinct pathological changes in two left femurs and one left pelvic bone fragment from the Necropolis of Santa Maria, Sintra (Portugal), dated from the 14-17 centuries. The differential diagnosis of the lesions gave rise to several possible pathological conditions, namely, slipped femoral capital epiphysis, Legg-CalvéPerthes diseas...
