- Variability between Clarke's angle and Chippaux-Smirak index for the diagnosis of flat feet Cristina Gonzalez-Martin Salvador Pita-Fernandez Teresa Seoane-Pillado Beatriz Lopez-Calviño Sonia Pertega-Diaz Vicente Gil-Guillen Medicina Foot Chippaux Podiatry Flatfoot Footprint Background: The measurements used in diagnosing biomechanical pathologies vary greatly. The aim of this study was to determine the concordance between Clarke's angle and Chippaux-Smirak index, and to determine the validity of Clarke's angle using the Chippaux-Smirak index as a reference.Methods: Observational study in a random population sample (n= 1,002) in A Coruña (Spain). After informed patient consent and ethical review approval, a study was conducted of anthropometric variables, Charlson comorbidity score, and podiatric examination (Clarke's angle and Chippaux-Smirak index). Descriptive analysis and multivariate logistic regression were performed. Results: The prevalence of flat feet, using a podoscope, was 19.0% for the left foot and 18.9% for the right foot, increasing with age. The prevalence of flat feet according to the Chippaux-Smirak index or Clarke's angle increases significantly, reaching 62.0% and 29.7% respectively. The concordance (kappa I) between the indices according to age groups varied between 0.25-0.33 (left foot) and 0.21-0.30 (right foot). The intraclass correlation coefficient (ICC) between the Chippaux-Smirak index and Clarke's angle was -0.445 (left foot) and -0.424 (right foot). After adjusting for age, body mass index (BMI), comorbidity score and gender, the only variable with an independent effect to predict discordance was the BMI (OR= 0.969; 95% CI: 0.940-0.998).Conclusion: There is little concordance between the indices studied for the purpose of diagnosing foot arch pathologies. In turn, Clarke's angle has a limited sensitivity in diagnosing flat feet, using the Chippaux-Smirak index as a reference. This discordance decreases with higher BMI values. 2017 artículo científico 0120-8322 https://www.redalyc.org/articulo.oa?id=28351074004 https://www.redalyc.org/journal/283/28351074004/ https://www.redalyc.org/journal/283/28351074004/html/ https://www.redalyc.org/journal/283/28351074004/28351074004.epub https://www.redalyc.org/journal/283/28351074004/movil en http://www.redalyc.org/revista.oa?id=283 Colombia Médica application/pdf Universidad del Valle Colombia Médica (Colombia) Num.1 Vol.48
