Prognostic Value of Modified Lateral Pillar Classification in Legg-Calvé-Perthes Disease

چکیده
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 months). Lateral pillar C classification was divided into C1 (50-75% collapse of the lateral pillar) and C2 (> 75%). All radiological and clinical prognostic factors were evaluated. The final results were evaluated according to the Stulberg classification. RESULTS Twenty one and 18 of the affected hips were in groups C1 and C2, respectively. According to the Stulberg classification, the final results of group C1 were better than those of C2 (p = 0.002). Patients with more head-at-risk signs had significantly poorer outcomes. CONCLUSIONS The modified lateral pillar classification has significant value for predicting the prognosis of LCPD.

Evolution in diagnosis and treatment of Legg-Calve-Perthes disease
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...
متن کاملRadiographic classifications in Perthes disease
Background and purpose - Different radiographic classifications have been proposed for prediction of outcome in Perthes disease. We assessed whether the modified lateral pillar classification would provide more reliable interobserver agreement and prognostic value compared with the original lateral pillar classification and the Catterall classification. Patients and methods - 42 patients (38 bo...

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...
متن کاملClassifications in brief: the Herring lateral pillar classification for Legg-Calvé-Perthes disease.
Classifications of Legg-Calvé-Perthes disease (LCPD) may be divided into three categories: those defining the stage of the disease, those attempting to prognosticate outcome, and those defining outcome. Although Arthur Legg MD [13], Jacques Calvé [2], and Georg Perthes MD [17] share credit for their descriptions of the disease published between 1909 and 1910, according to Wenger and Pandya, Hen...
متن کاملWhat Is the Usefulness of the Fragmentation Pattern of the Femoral Head in Managing Legg-Calvé-Perthes Disease?
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...
