BACKGROUND Accurate and reliable radiographic classifications of the relative severity and outcome of Legg-Calve-Perthes disease are essential in the study of that disease. As part of a prospective multicenter study, we sought to define more clearly the lateral pillar classification of severity and the Stulberg classification of outcome; we sought especially to define the borderlines between cl...

In this paper we wish to emphasise the danger of avascular necrosis of the capital femoral epiphysis arising as a late complication of osteomyelitis of the intertrochanteric region. This necrosis is primarily aseptic and is believed to follow interference with the vulnerable vascular channels supplying the capital femoral epiphysis rather than spread of infection into the joint. If, however, th...

Background Legg-Calve-Perthes (LCP) disease during early childhood might lead to impaired blood circulation the femoral head causing osteoarthritis and avascular necrosis of head. In most cases children diagnosed after age nine years, progression LCP is associated with poor outcomes disability. This study aimed evaluate clinical radiological varus derotation osteotomy in LCD a late presentation...

Synonyms for this disease include “avascular necrosis of the femoral head” and “aseptic necrosis of the femoral head”, “Perthes disease” and “Legg Perthes” disease, “osteochon-dritis”, “coxae juvenilis”, “coxa plana” and “idiopathic osteosis”. The terms “avascular/aseptic necrosis of the femoral head” are also used to describe a process of femoral head necro-sis in dogs following traumatic frac...
