Abstract
in English, French

The purpose was to evaluate the value of radiology to distinguish between symptomatic and asymptomatic flexible flatfeet in young male adults. Among young male army recruits, 56 feet of 28 recruits were diagnosed as otherwise normal, flexible flatfoot with invisible longitudinal arch on stance and either symptomatic or asymptomatic unilaterally or bilaterally. The talus-first metatarsal and calcaneal pitch angles were measured on weight-bearing lateral radiographs, and the results were evaluated statistically. The talus-first metatarsal angle showed statistical significance in both non-parametric and logistic regression tests, but the calcaneal pitch angle showed statistical significance only in non-parametric test between symptomatic and asymptomatic flatfoot groups. Although the single gender and number of samples limit the applicability of our study, these results caused us to make an interpretation that increased talus-first metatarsal angle might be an important risk factor of being symptomatic in otherwise normal flexible flatfoot.

Le but de cette étude est d’évaluer la valeur de la radio dans les pieds plats d’adultes jeunes qu’il soit symptomatique ou asymptomatique.Matériel et méthode : parmi des sujets recrutés dans l’armée, 56 pieds sur 28 recrues ont été considérés comme plats avec ou sans symptômes, qu’ils soient uni ou bilatéraux. L’angle astragale premier métatarse et le calcanéum a été mesuré en charge sur des radiographies de profil.Résultats : cet angle a une valeur significative seulement dans le test non paramétrique entre le groupe des pieds plats symptomatiques et des pieds plats asymptomatiques.Conclusion : ces résultats nous permettent de penser que l’aggravation de cet angle est un important facteur de risques d’évolution symptomatique chez les sujets avec pieds plats normaux, asymptomatiques.
