Asymmetry of the thigh and hip lines of the baby’s lower limbs is a concern for many parents, and the biggest worry is whether the baby has unilateral hip dislocation. This is a developmental hip dislocation, and if it can be detected, the earlier the treatment, the better the result. However, because nowadays babies are fed properly, are relatively fat, fat accumulation will also lead to hip and leg lines asymmetric, so this situation is not necessarily a developmental hip dislocation, you can ask the pediatrician or orthopedic surgeon to check: check, the baby lying on his back, to observe whether the two lower limbs are equal in length, equal in length is normal, the two lower limbs are unequal, said that there may be a unilateral dislocation of the hip joints. The baby is lying on his back and bending the hip and knee and putting both feet on the bed, if the height of both knees is equal, it is normal, when the unilateral hip is dislocated, the height of both knees is not equal, and ultrasound can be done to further confirm the diagnosis. Do babies with ”O” shaped legs and “inside eights” need to be treated? Many babies’ calves are a little bent before the age of 2, and will grow straight later. Some babies have a certain degree of “inward curvature”, which usually disappears after 7 years of age. Whether the baby has “O-shaped legs” or “internal eights”, it is only a slight deviation from normal, and does not need treatment. Braces, orthopedic shoes and special training are generally useless, and may even hinder the baby’s physiological development and cause unnecessary psychological stress. Very few babies with “O-shaped legs” or “internal eights” are caused by disease and need to be treated by a doctor. Vitamin D deficiency rickets can cause O-shaped legs, therefore, the baby must take vitamin D preventive amount before the age of 3, 400 international units per day. Here also want to say, many of the old generation will be through the small months of age of the baby tied candle package or tied legs to “prevent” the baby legs not straight, this practice does not have any scientific basis, very undesirable. Tying candles and legs will limit the baby’s space to move, and on the other hand, tying too tightly can lead to the hip dislocation mentioned above, so please be careful. If you want to swaddle your baby, you can adopt a tight top and loose bottom wrapping method. What to do if your baby has pronated feet The phenomenon of your baby’s toes tucking in when he walks is called pronated feet. There are two types of this condition, one occurs during infancy and the other occurs after the age of 2 years. Both have a familial tendency to occur. The most common cause of inward tucking of the front of the toes at birth is that the fetus is squeezed into a narrow uterine space. It is characterized by an inward tucking at the front of the foot and a crescent-shaped, raised, curved gnarl on the outside of the foot, which is relatively mild and usually recovers on its own at 1 year of age. Parents can give the child a reset massage, which is conducive to recovery. At the age of 2 years, the baby develops a foot with an inward curvature, which is often caused by the tibia bone twisting to the inside. This kind of pronated foot will heal on its own after some time. If your child’s hallux valgus foot does not improve by the age of 3 years or older, you can consult a surgeon.
