Leg curvature at birth usually resolves around 6 to 12 months of age, and leg curvature that occurs after 1 year of age does not recover on its own without effective treatment.
Leg curvature at birth is a normal physiological phenomenon related to the position of the fetus in the mother’s body. With the normal growth and development of the child, leg curvature usually improves gradually after 6 months.
However, if the infant’s body lacks vitamin D, causing abnormal deformation of bone development, the child’s legs gradually develop into O-shaped legs or X-shaped legs, which is clinically known as vitamin D deficiency rickets, then this condition can not be recovered on its own if it is not treated in time.
Therefore, it is necessary to give vitamin D to newborns to prevent rickets. At the same time, parents should be guided by the doctor to the baby’s leg manipulation intervention, to promote the baby as soon as possible to straighten the legs.
