What should children do when they walk "outside eight characters, inside eight characters"?

"Doctor, how can our children walk in figure 8? Too ugly! " , "what? Maybe it will get better when I grow up. Girls! What if it is not good in the future! " "We heard that children's problems should be treated early, otherwise they will not be corrected in the future. Is there any good way to make him get better soon? " These are common problems in pediatric orthopedic clinics. During fetal development, the lower limbs gradually bend to adapt to the narrow space in the uterus. When the first fetus, oligohydramnios, breech position, uterine malformation and fetal size are too large, the fetus, especially the lower limbs, is most vulnerable to compression and deformation. Moreover, because the posture of each fetus in the uterus is different, the deformation at birth is also inconsistent, some are varus and some are eversion. Generally speaking, the calf has obvious pronation bending, while the hip joint is in flexion and supination posture. So some parents say that their children are different from their neighbors' children, of course. After birth, most of this deformation caused by intrauterine compression can return to normal as long as the compression is lifted. Some people with genetic predisposition are unlikely to recover naturally and need special attention and treatment. N After learning to walk, some children who have just learned to stand will get better, and parents will notice the obvious phenomenon of "external eight characters". When standing, your feet curl outward, almost in a straight line. This kind of child's lower limbs are prone to eversion, but the internal rotation is quite tight. This is because the child's hip joint flexes and rotates outward in the fetal period, which leads to the tension of the external rotator of the hip joint. Generally speaking, after you start walking, your muscles can relax and your external horoscope will gradually improve. If you really want to do something to speed up your recovery, it is recommended to do lower limb internal rotation. Because few people come to see a doctor when they grow up, it is enough to prove that this situation will naturally get better. Children with eight characters in N need "lacing". As for n, there are quite a few. As mentioned above, most fetuses are in the state of varus, calf pronation and hip flexion in the uterus. Therefore, after giving birth, some children have varus due to too much intrauterine pressure, but their flexibility is still quite high, that is to say, they can be pulled back to their normal positions with a slight force, and joint activities are not restricted. Generally speaking, this situation does not require treatment. At best, as long as you do "stretching" exercise, that is, massage outward and upward, you will return to normal in a month or two. This is different from "clubfoot". The foot of clubfoot has been deformed, the heel is tight, it is not easy to pull back to the normal position, and the movement in all directions is also restricted. Treatment must be covered with plaster, and those who have not fully recovered need surgery. N There is also a situation where children under one year old are corrected by massage, corrective shoes and plaster, that is, metatarsal adduction, which is different from varus foot. When the metatarsal bone is adducted, only the front end of the foot bends inward, and its softness varies with each child. If you can easily pull back to the normal position, you don't need special treatment, just stretch your muscles and massage. If considerable force is needed to pull back to the normal position or it cannot be completely pulled back to the normal position, corrective shoes or plaster are needed for treatment. Only in this case, it makes sense to change shoes left and right, and the inside of the shoes should be hard. We believe that the effect of customized orthopedic shoes or gypsum is relatively certain. A few serious people, after four years old, the front end of their feet still bends inward, which is unsightly and affects wearing shoes. Some people think that this kind of foot is prone to hallux valgus deformation in the future This situation can be considered for surgical correction. N Sleeping on your stomach and kneeling, O-shaped legs are not easy to get better over one year old. Children under three years old, especially toddlers, are most often in the shape of an inner character, which will merge with O-shaped legs. The reason is that the calf pronation caused by fetal position is completely restored, and the stability of the child is not enough. The foot needs to be opened to stabilize the pronation of the foot. This situation, with the growth of age, the development of nerves, muscles and ligaments is becoming more and more mature, and will gradually return to normal, so parents don't have to worry. However, prone sleeping and kneeling posture hinder its natural recovery and should be avoided as much as possible. Children with "TV legs" encourage them to sit in the pan. Children under three years old, especially girls, have different reasons for taking the figure of eight, all of which are caused by excessive forward leaning of the upper femur. Because of this kind of bone problem, when a child walks, his lower limbs must rotate inward, that is, in the shape of an inner figure of eight, which is more powerful and stable. When parents often tell their children to walk straight or pay special attention, children can "walk well", but if they don't pay attention, they will "relapse". In fact, children don't mean it. Walking upright is really laborious and tiring. This kind of child likes to sit back and spread his feet back, which is the "W" sitting posture, or commonly known as "TV feet". When running fast, his calf kicked backward and outward, which was very ugly. Because girls are more likely to have this kind of situation, and they have grown up gradually, especially if someone in their family has not fully recovered, so parents are more worried and hope that doctors can cure this problem quickly. However, according to foreign long-term research, any corrective shoes or brackets have no corrective effect on the internal splay caused by the anteversion of the upper femur. It may be better to wear a bracket, but it will return to its original state without it. It is generally recommended in the medical field that sitting backwards is absolutely forbidden, because it hinders the natural recovery of femoral anteversion and encourages sitting backwards. Another thing worth encouraging is riding a bike or skating, because in these two sports, the feet must be outward. Children over the age of eight receive surgical treatment. Although most of the internal splays caused by femoral anteversion will get better, some people still have persistent problems. Some people have compensatory calf external rotation, and they will not have internal splays when walking, but their knees are inward. Whether this kind of person is more likely to get knee arthritis or physical arthritis in the future, although some people doubt it, it is still inconclusive. Therefore, unless you are particularly bad at walking and easy to trip yourself, and you are over eight years old and have compensatory external rotation at the end of your calf, you can consider surgical treatment, osteotomy to correct the internal splay phenomenon, and your appearance and walking can be improved. In short, the "internal horoscope" or "external horoscope" is somewhat hereditary, which is basically an extension of posture in the fetal period, and will return to normal in the process of growth and development, with some posture obstacles.
