Most of the newborn’s leg bending is a normal phenomenon, it may also be caused by disease factors, such as congenital hip dysplasia, rickets and so on.
1. Normal phenomenon: newborns grow up in the womb before birth, limited space in the womb, the fetus in the womb in order to adapt to the environment and does not affect the growth of the limbs as much as possible to bend, especially the legs bent inward, which is a normal phenomenon, with the newborns slowly grow up, the leg bends will gradually get better.
2. Congenital hip dysplasia: it is a congenital malformation, which can be seen as excessive flexion of the lower limbs, external rotation, bilateral dermatoglyphic asymmetry, etc., which will trigger the phenomenon of neonatal leg bending.
3. Rickets: if the newborn’s body lacks vitamin D, it will be prone to vitamin D deficiency rickets, rickets will trigger newborn leg bending phenomenon.
There may be other reasons for newborns legs bent, after excluding physiological factors, it is recommended to improve the relevant examinations in a timely manner, so as to avoid delay in treatment.
