Legg-Calve-Perthes disease (LCPD) is a degenerative condition of the hip joint characterised by idiopathic avascular necrosis of the femoral head. Loss of bone mass causes a degree of collapse of the joint and may result in deformity of the ball of the femur and the surface of the hip socket. A reduction in hip joint range of motion, alternation in growth of femoral head, and associated pain ar...

BACKGROUND Coxa profunda is commonly viewed as a radiographic parameter that is indicative of pincer-type femoroacetabular impingement, and this finding can impact diagnostic and surgical decision-making. Validation of coxa profunda as a measure of pincer-type femoroacetabular impingement has not been rigorously analyzed. Our hypothesis was that coxa profunda is a very common radiographic findi...

We develop a point-vortex equilibrium statistical model for baroclinic quasigeostrophic vortices within the context of a two-layer quasigeostrophic fluid that evolves in all of space. Angular momentum, which follows from the rotational symmetry of the unbounded domain, is the key conserved quantity, introducing a length scale that confines the most probable states of the statistical theory. We ...

The aim of this paper is to determine the late results of idiopathic pseudocoxalgia (Legg-Calv#{233}-Perthes disease) in adult life. It is hoped to obtain some idea of the efficiency of treatment and of the factors that influence prognosis. In the enormous literature of this condition, only three papers can be found which contain reports of cases which have been observed for long periods. Legg ...

BACKGROUND Legg-Calve´-Perthes disease is a juvenile idiopathic osteonecrosis in which the blood supply of femoral head is not sufficient and the bone dies provisionally. The aim of this study is to evaluate outcome of Femoral osteotomy in children with LCPD in our University Hospital. METHODS In a descriptive analytic study, between 2008 and 2013, patients with the diagnosis of Legg-Calve'-P...

Legg-Calve-Perthes (LCP) disease is characterized by idiopathic avascular osteonecrosis of the epiphysis of the femur head. The main factor that plays a role in the etiology of the disease is decreased blood flow to the epiphysis. Many predisposing factors have been suggested in the etiology of LCP disease, and most have varying degrees of effects. Here we present the case of a boy aged 4 years...

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...
