This obtuse angle is what we mean by the name of genu valgum physiologicum. Many clinicians forget this physiological phenomenon; others, with Lange and Spitzy at the head, believe that the X-foot is formed only in the 2nd year, considering the characteristic for the 1st year of life the O-foot, which is the result of adaptation to the ovoid shape of the uterine cavity.</p>Kazan Medical archiveКазанский медицинский архив
