hi,I am quoting some of the causes of bowing of legs in children
Parents of children who have bowed legs often want to know if the child's legs are abnormal. First, bowing or the technical term
genu varum (genu = knee, varus / varum = angles in) is a part of the normal development of a child. The role of the physician is to determine if the bowing is physiologic (part of normal development) or pathologic (due to some disease process). Physiologic bowing will improve as the child grows without treatment, while pathologic bowing will tend to worsen over time without treatment. Many disease processes effecting bone growth cause pathologic bowing. Two of the more common diseases known to cause bowing are
Rickets and Blount's disease.
