BACKGROUND: Although hinge abduction is recognized as an important finding in children with Legg-Calvé-Perthes disease, variable diagnostic criteria exist. The purpose of this study was (1) to test the interobserver and intraobserver agreement of the current definition of hinge abduction and (2) to develop consensus regarding key diagnostic features that could be used to improve our diagnostic criteria. METHODS: Four orthopaedic surgeons with subspecialty pediatric hip interest independently assessed 30 randomly ordered cases of Legg-Calvé-Perthes disease...

BACKGROUND: Evaluating postoperative patients with hardware is challenging following surgical intervention for hip maladies such as femoral neck fractures and slipped capital femoral epiphysis (SCFE). These children are at increased risk of developing avascular necrosis, and imaging may be requested to confirm or exclude this diagnosis. Children with Legg-Calvé-Perthes disease can be monitored for restoration of blood flow to the capital femoral epiphysis to guide management and help with prognosis...

BACKGROUND: The Herring lateral pillar classification is widely used for the classification of Legg-Calvé-Perthes disease, but is not applied at the early stage of Legg-Calvé-Perthes disease because it is typically applied at the late fragmentation stage. The purpose of this study was to investigate the correlation between the early appearance on magnetic resonance imaging of the acetabular labrum and lateral pillar involvement in Legg-Calvé-Perthes disease. METHODS: Non-contrast magnetic resonance images of 26 hips in 25 children with early-stage Legg-Calvé-Perthes disease were retrospectively reviewed...

Current knowledge of the causes and risk factors of Legg-Calvé-Perthesdisease (LCPD) does not allow effective preventive strategies. The outcome in adulthood is usually good. Hip osteoarthritis rarely develops before 50 years of age. The risk of osteoarthrosis depends chiefly on the final degree of joint incongruence. Age at onset and the lateral pillar classification are the two main outcome predictors and serve to guide the surgical indications based on the studies by Herring's group. Non-operative treatment is not effective...

INTRODUCTION: The goal of intervention in Legg-Calvé-Perthes disease (LCPD) is to prevent femoral head deformation by containing the head within the acetabulum. Currently, surgical containment methods are the mainstay of treatment, and pelvic osteotomies have been shown to be successful. They include triple pelvic osteotomy (TPO), Salter osteotomy, Chiari osteotomy and shelf procedure. The purpose of this study was to compare clinical and radiologic results for Chiari osteotomy and TPO in LCPD...

BACKGROUND: Most of the information available about Legg-Calve-Perthes disease (LCPD) at present is gained through imaging modalities including plain radiographs and magnetic resonance imaging (MRI). But the accuracy of MRI in this disease and its predictive value to reveal various intra-articular pathologies is not known. We correlated the findings of MRI with those seen on hip arthroscopy in children with active stage of LCPD. METHODS: We conducted a prospective observational study in which MRI findings were correlated with corresponding findings on hip arthroscopy in a cohort of 25 patients of active LCPD below 12 years of age...

BACKGROUND: The role of vascular endothelial growth factor (VEGF) after ischaemic necrosis of the femoral head in Legg-Calve-Perthes disease (LCPD) has not been adequately studied in humans, especially in Indian population. Therefore, we aimed to evaluate the serum levels of VEGF-A in Indian children with various stages of LCPD and compare them with those of an age- and sex-matched control group of healthy children. METHODS: In this case-control study, we enrolled 42 children (below 14 years age) suffering from LCPD and 21 age- and sex-matched healthy controls...

BACKGROUND: Variations in femoral and acetabular version are becoming increasingly recognized as contributing factors to the development of hip pain in patients with femoroacetabular impingement (FAI) and hip dysplasia. It is still unknown what the true prevalence of these rotational abnormalities is in this patient population. PURPOSE: To determine (1) the prevalence of femoral version abnormalities in symptomatic hips with FAI and hip dysplasia, (2) the prevalence of combined abnormalities of femoral and acetabular version in these patients, and (3) which specific hip morphologies are associated with abnormalities of femoral version...

Legg-Calve-Perthes disease (LCPD) is a childhood form of ischemic osteonecrosis marked by development of severe femoral head deformity and premature osteoarthritis. The pathogenesis of femoral head deformity has been studied extensively using a piglet model of ischemic osteonecrosis, however accompanying acetabular changes have not been investigated. The purpose of this study was to determine if acetabular changes accompany femoral head deformity in a well-established piglet model of LCPD and to define the acetabular changes using 3 dimensional computed tomography (3-D CT) and modeling...

This is a retrospective observational study. Greater trochanteric epiphysiodesis (GTE) has been recommended to prevent Trendelenburg gait and limitation of the hip joint motion due to trochanteric overgrowth after femoral varus osteotomy (FVO) in Legg-Calvé-Perthes disease (LCPD). However, capital femoral physeal arrest frequently occurs in patients with severe disease (lateral pillar C), so GTE might not be as effective in these patients. The aim of this study was to compare trochanteric growth inhibition due to GTE after FVO between 2 age groups (<8 or >8 years) in patients with lateral pillar B and B/C border LCPD and evaluate the effectiveness of GTE compared with the normal, unaffected hip...

Parvinder Sujlana, Jan Skrok, Laura M Fayad
Although postcontrast imaging has been used for many years in musculoskeletal imaging, dynamic contrast enhanced (DCE) MRI is not routinely used in many centers around the world. Unlike conventional contrast-enhanced sequences, DCE-MRI allows the evaluation of the temporal pattern of enhancement in the musculoskeletal system, perhaps best known for its use in oncologic applications (such as differentiating benign from malignant tumors, evaluating for treatment response after neoadjuvant chemotherapy, and differentiating postsurgical changes from residual tumor)...

INTRODUCTION: Legg-Calvé-Perthes Disease (LCPD) represents idiopathic avascular necrosis of femoral head in pediatric population. Indications for treatment depend mostly on prognosis about femoral head sphericity and hip congruence at the end of growth. The aim of this review is to highline prognostic factors of LCPD. METHODS: Bibliographic search in PubMed allowed selection of 33 articles concerning prognostic factors and/or classification of LCPD. CONCLUSION: Clinical factors of poor prognosis are overweight, female sex, age exceeding 6 years old, and lack of hip abduction...

BACKGROUND: Arthroscopic labral base repair (LBR) in the hip is a previously described technique designed to restore the native functional anatomy of the labrum by reproducing its seal against the femoral head. LBR has been shown to have good short-term outcomes. Hypothesis/Purpose: The purpose was to evaluate clinical outcomes of an LBR cohort with a minimum 5-year follow-up. It was hypothesized that patients who underwent LBR would continue to have significant improvement from their preoperative scores and maintain scores similar to their 2-year outcomes...

The periacetabular quadruple osteotomy of the pelvis (QOP), with the osteotomy of ischial spine to release the sacrospinal ligament, is reserved for older children with low potential of remodeling. Different parameters were studied with computed tomography (CT) scan before (pre-OH) and after surgery (post-OH) and for nonoperated hip (NOH). The study determined an optimal method to avoid retroversion and excessive anterior coverage. Fifteen QOP were performed in 13 patients, ranging in age from 10 to 15 years...

BACKGROUND: Total hip arthroplasty (THA) in patients with sequelae of Legg-Calvé-Perthes disease (LCP) is technically demanding because of the disease related deformities occuring in the proximal femur and/or the multiplanar deformities secondary to corrective osteotomies in childhood. Little is known about the long-term outcome of the procedure in this challenging group of patients. METHODS: We carried out a systematic review of the literature to determine the functional outcome, complications and revision rate of THA in patients with sequelae of LCP disease...
