Many people see that their children have o-shaped legs, which may be caused by sleeping posture or other factors such as genetics. When they find out that their child has o-shaped legs, some parents plan to start correcting them when the child is small, so that it will be difficult to correct the o-shaped legs when the child grows up and the bones are set. So, when is the best time to correct o-leg in children? The best time to correct O-leg is the period of infancy, at this time, the child’s bones have not been fully formed, and can still affect the shape of the bones through the correction afterwards, so patients with O-leg will get the best results if they correct it at this time. However, it is not true that the correction cannot be done at other times except during infancy, in fact, it is possible, but often the effect is not as good as during infancy, and it will often take a long time to correct, so if your child has O-leg, it should be adjusted in time. Do not think that O-leg just affects the aesthetics, in fact, O-leg may lead to more serious situations, the first is rickets, which is also one of the most serious conditions caused by O-leg, because O-leg is the lack of vitamin D leads to bone problems, so it should still pay attention to.
