legg-calvé-perthes disease (lcpd) is an idiopathic osteonecrosis of the femoral head with variable complications and resultant deformity of the femoral head and osteoarthritis. suggested risk factors are acetabular retroversion, obesity, latitude, hyperactivity, and coagulopathy. the most commonly applied classification is based on radiolucency in the lateral pillar of the femoral head, which i...

OBJECTIVES The objective of this study was to investigate cases of femoroacetabular impingement (FAI) and analyze the risk factors for a painful hip at skeletal maturity after Perthes disease. We hypothesized that FAI occurs as a sequela of Perthes disease and that coxa plana and triple osteotomy of the pelvis (TOP) may be risk factors. METHODS Ninety-five hips were included from 1981 to 2011...

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...

The possible role of coagulatory disorders in pathogenesis of Legg-Calve-Perthes disease (LCPD) and osteochondrosis (OC) was examined. A decrease in protein C level in dogs with LCPD (94.31±4.74%) in comparison with healthy dogs (95.8±6.35%) was observed. Moreover, in OC affected animals, the value varied between 92.25±2.5% and 94.33±5.5%. The mean plasma fibrinogen level in control group was 2...

Introduction: Legg-Calve-Perthes Disease (LCPD) is a complex condition with limited understanding about its healing process. The mechanism of LCPD believed to differ significantly from adult hip avascular necrosis (AVN), thus necessitating an exploration into alternative mechanisms. Our research focused on these mechanisms using review histologic specimens, thorough literature review, and trans...
