INTRODUCTOIN: Legg-Calve-Perthes disease (LCPD) is a common juvenile form of ischemic osteonecrosis of the femoral head that affects children between the ages of 2 to 14 years and has the attack rate of 1 in 740 boys and 1 in 3700 girls. LCPD is due to blood supply disruption to the femoral head. Ischemic osteonecrosis of the femoral head remains one of the most challenging conditions to treat ...

”Intelligence” is a natural language, ”folk psychology” concept, with all the imprecision and contextuality that this entails. One cannot expect any compact, elegant formalism to capture all of its meanings. Even in the psychology and AI research communities, divergent definitions abound; Legg and Hutter [6] lists and organizes 70+ definitions from the literature. Practical study of natural int...

Femoral varus osteotomy (FVO) has been widely used in the surgical treatment of Legg-Calve-Perthes disease (LCPD). Axer in 1965 reviewed FVO as a treatment of LCPD and reported a very favorable results comparing with those observed after conservative treatment. Since then, many authors have demonstrated that it can prevent femoral head deformity and restore spherical congruity, provided that th...

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...

  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-Calv...

Thirty-two patients (out of 52 undergoing surgery) with Legg-Calvé-Perthes disease (LCP) were examined retrospectively to assess the efficacy of surgical treatment on epiphyseal morphology at the primary healing. The analysis of the clinical results of the 33 hips considered indicated that it is necessary to operate above all on 3rd grade hips. For these the most frequent operation indicated is...
