Meyer's dysplasia strongly mimics Legg-Calve-Perthes' disease despite differing markedly in eventual outcome. This study presents the clinicoradiologi-cal features which differentiate it from Perthes' disease in a group of 178 children with a preliminary diagnosis of Perthes' disease, of whom nine were subsequently diagnosed with Meyer's dysplasia. All had a near normal development of the femor...

BACKGROUND Legg-Calvé-Perthes disease (LCPD) is an idiopathic hip osteonecrosis prevalent in children < age 15 years. The etiology remains incompletely understood, partly because of multiple potential environmental risk factors and partly because of lack of genetic markers. It has been hypothesized that hyperactivity may induce mechanical stress and/or vascular damage at a fragile joint. OBJE...

In 1910, Legg, Calvé and Perthes described almost simultaneously the major features of a disease, which was, by that time, confused with hip tuberculosis. The disease is described as a self-limiting disorder affecting the hip, and is characterized by total or partial aseptic necrosis of the femoral head, yielded by blood supply interruption, followed by subchondral fracture, revascularization a...

OBJECTIVE Osteonecrosis of the hip has been reported in human immunodeficiency virus (HIV)-infected adults; whether this is related to HIV infection or its treatment is unknown. There has been 1 report of osteonecrosis among HIV-infected children. Specifically, avascular necrosis of the hip consistent with Legg-Calvé-Perthes disease (LCPD) was reported in 3 HIV-infected children with AIDS from ...

Background In a previous study, we reported clinical and radiographic results of our modified Salter innominate osteotomy technique in 16 hips affected by Legg-Calvé-Perthes disease (LCPD) with an average follow-up of 31.8 months. In this study, we present the long-term results of the osteotomy in LCPD patients followed until physeal closure. Methods Thirty hips of 29 patients were followed u...

BACKGROUND AND PURPOSE Hyperactive behavior pattern (such as attention deficit hyperactivity disorder (ADHD)) is proposed to be present in individuals with Legg-Calvé-Perthes disease (LCPD). We investigated whether individuals with LCPD have a higher risk of ADHD, depression, and mortality. SUBJECTS AND METHODS We identified 4,057 individuals with LCPD in Sweden during the period 1964-2011. 4...
