[Gait disorders and lower leg deformities in children].

Gait disorders and lower legs deformities in children are frequent causes of parental concern and of medical advice. These deformities should be analysed systematically as well as their consequences for daily activities. We should define precisely type, localisation and importance of the deformity: femoral or tibial torsion, knock knees, bow legs. The evaluation should always be done according to age of the child because these deformities are most often a step toward adult morphotype. Sometimes they could be the manifestation of some generalised or localised pathology that should be investigated and treated. Nevertheless patience and explanations, regular follow-up allow to reassure the parents. There is in the great majority of case no place for any conservatrice and especially surgical treatment for theses disorders spontaneously healing in 95% of cases.
