ABSTRACT

Introduction: The investigation on the medial longitudinal arch is aimed at addressing the diagnostic problems of flat foot. The diagnosis is currently based on clinical tests and the appropriate identification of both postural and gait abnormalities. Risk factors are associated with pre-school ages, but there is no adequate analysis of such factors during school ages, when the longitudinal arch reaches its conformational maturity. Material and methods: Probabilistic methods were used to obtain a sample of 476 patients from elementary schools in the Federal District and the state of Puebla. Once the approval of the research committee was obtained, an analytical, prospective, cross-sectional study was conducted. Anthropometric measurements were performed, together with anamnesis, physical exam of the students, and conventional wet footprint analysis in a standardized and duplicate way. Results: Of the 476 patients, 101 had flat foot (21.2%) and 49 of them had pain symptoms in the feet, knees or both (48.5%), accounting for 10.2% of the patients examined. Forefoot pronation and valgus hindfoot resulted in an increased risk of symptomatic flat foot in the school population in the study. Conclusions: In cases of flat or cavus foot, the presence of foot and/or knee pain symptoms in the school population was associated in a statistically significant way with one or more of the factors analyzed (overweight, genu valgus, valgus hindfoot, forefoot pronation and claw toes). Girls with such factors had a 3-7 higher chance of having symptomatic flat foot.
