BACKGROUND Accurate and reliable radiographic classifications of the relative severity and outcome of Legg-Calve-Perthes disease are essential in the study of that disease. As part of a prospective multicenter study, we sought to define more clearly the lateral pillar classification of severity and the Stulberg classification of outcome; we sought especially to define the borderlines between cl...

OBJECTIVES To determine whether the clinical variables and preoperative classification of patients with Legg-Calvé-Perthes disease (LCPD) who undergo Salter osteotomy correlate with the radiographic result at the time of skeletal maturity. METHODS In this retrospective cohort study, 47 individuals with LCPD who were treated using Salter osteotomy (1984-2004) were evaluated. The patients were ...

In this study, clinical and radiological results were evaluated in patients with Legg-Calve-Perthes disease treated with Salter pelvic osteotomy. Between 2004 and 2008, 16 patients underwent a Salter osteotomy as treatment for Legg-Calve-Perthes disease (15 male, 1 female; 10 right hip, 6 left hip). The mean age at the time of surgery was 8.1 +/- 1.4 (range: 6 to 10) years. Surgical indications...

BACKGROUND Standard treatments may provide adequate containment in mild to moderate Legg-Calve-Perthes disease (LCPD), but they can be problematic in more severe cases. The purpose of this study was to report the results of combined shelf acetabuloplasty with femoral varus osteotomy in severe LCPD. METHODS We reviewed 12 patients who had undergone combined shelf acetabuloplasty with femoral v...

The goal of all therapies for Perthes' disease is to achieve an optimal shape of the acetabulum and an optimal coverage of the femoral head. Thirty patients who were included in this follow-up study (mean follow-up 12 years) underwent a shelf acetabuloplasty for Catterall group III or IV. The mean IOWA hip score at follow-up was 96 (max. 100 points, range 74-100). The mean acetabular-head quoti...

BACKGROUND To evaluate the usefulness of the modified lateral pillar classification as a prognostic factor in Legg-Calvé-Perthes disease (LCPD). METHODS Thirty nine patients diagnosed with lateral pillar C in LCPD from May, 1977, to October, 2001 were reviewed, and their skeletal maturity was followed. The mean follow up duration was 12 years and 7 months (4 years, 6 months to 24 years, 9 mon...

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...

BACKGROUND Within the lateral pillar classification of the Legg-Calvé-Perthes (LCP) disease, hips seem quite variable in the pattern of fragmentation as seen in radiographs. The purpose of this study was to determine: if it is possible to reliably subdivide the lateral pillar groups into femoral head fragmentation patterns, and if such a subdivision of the lateral pillar groupings is clinically...

BACKGROUND To evaluate the efficacy of arthrodiastasis for Legg-Calve-Perthes disease. METHODS Arthrodiastasis was conducted using external fixator devices (Orthofix) in 7 patients at least 8 years of age with a diagnosis of Legg-Calve-Perthes disease. The average follow-up was 80 months (range, 32 to 149 months), and their average age was 9.1 years (range, 8 to 12 years). The results of trea...

BACKGROUND The prognosis for children in whom Legg-Calvé-Perthes disease develops before the age of six years was initially reported to be good, but later studies demonstrated a less favorable prognosis. To assess the natural history of this condition in this age group, we reviewed a large cohort of children who had received minimal treatment for the disease. METHODS The medical records and r...
