During the physical examination, the doctor will ask the mothers to take off the baby's diapers and turn over to take a look, which is to check whether the baby's hip lines are symmetrical.
Baby's hip wrinkles refer to the skin folds between the baby's buttocks, while the asymmetry of the buttocks refers to the difference in depth, lightness, length, shortness, number, position, etc. of the baby's hip lines on both sides.
Asymmetry of hip striae in infants and young children is actually a very common normal physiological phenomenon.
Babies have a lot of fat, and the fat accumulation is asymmetrical
Some small babies have more fat, the skin wrinkles on the body will be more, and the legs are shorter and smaller than adults, which can easily lead to asymmetrical accumulation of fat, resulting in asymmetry of hip lines.
In general, the baby's legs can move normally and the amplitude of movement is symmetrical. Parents don't have to worry too much, and they don't have to think of ways to correct it.
Hip dysplasia
Hip dysplasia refers to a range of diseases associated with hip development that may occur in infants and young children.
If the hip is dysplasia, it cannot form a normal joint "nest", which causes the hip joint to be too loose, so that the joint "ball" can easily slide out of the joint. Once the joint "ball" has completely slipped out of the joint, then a joint "dislocation" occurs.
Hip dysplasia may occur during the fetal period or after birth, and babies with this disease generally have other manifestations in addition to asymmetric hip lines, including:
asymmetry of leg striations (asymmetry of skin folds between the baby's thighs and calves);
The leg on the side where dysplasia occurs will appear shorter;
The hip movement on the side of dysplasia is limited, there is little strength, and the legs often maintain a bent posture and are reluctant to straighten;
When the mother changes her baby's diapers or bathes, she can always hear abnormal joint bouncing sounds.
In fact, most babies with asymmetric hip streaks do not mean that there is hip dysplasia. Therefore, parents do not have to worry too much.
However, for the sake of caution, it is best to take your baby to the pediatric or child health department as soon as possible for a detailed examination. If necessary, hip ultrasound (babies under 6 months) or X-rays (babies over 4 to 6 months old) are also done to further diagnose whether hip dysplasia has occurred.
To prevent asymmetrical hip lines, mothers need to pay attention to the fact that in daily life, the baby's legs have enough room for movement.
In daily care, it is best for mothers to do the following two things to ensure the movement space of the baby's legs, so that the legs can be bent up and out of the hips. This is beneficial to the natural development of the hip joint and minimizes the risk of hip dysplasia and dislocation.
1. Do not wrap the newborn baby's butt and legs tightly together, let alone leggings for the baby, and always ensure that the baby's legs have enough room to move;
2. In daily life, you should hold or carry the baby in the correct position, so that the baby's legs can naturally maintain a "frog posture", and avoid forcibly holding the baby's legs together.
