Medical guidance/Director of Children's Orthopaedics Department of the Third Affiliated Hospital of Southern Medical University
Does the asymmetry of baby's buttock lines possibly hide diseases? yes! What should I do with my baby's "O" leg and "8" character when walking? Don't be too tangled. Recently, Professor Li Xu, Director of Children's Orthopaedics Department of the Third Affiliated Hospital of Southern Medical University, visited the Guangzhou Daily Health Appointment Doctor Microclass to explain in detail various problems of bone health in various stages of children's growth, overturning many people's understanding of children's bone development. For example, valgus deformity of the knee joint is common in many cases. O-shaped legs, X-shaped legs and even every child must grow up. Not every kind of bone development that seems to be "abnormal" requires "calcium deficiency".
Observation of gluteal wrinkles and early intervention without surgery
Li Xu introduced that when the baby was born, some bone problems were easier to find directly, but some problems were more hidden. For example, the incidence of developmental dysplasia of the hip joint is one thousandth in clinic, but most of the children go to the hospital only after they walk independently and have abnormal gait after the age of one year. At this time, surgical intervention is often required, and the effect is naturally not as ideal as that of early detection.
In fact, this disease can be observed at the earliest time when a child is born, so that it can be treated with the simplest method to avoid surgical intervention.
The specific methods are: when the baby is 1 month old, carefully observe whether the skin lines (wrinkles) on both sides of the baby's thighs, the length of both legs are symmetrical, and whether the abduction of both hips is consistent or unilateral restricted; In case of any inconsistency, it is necessary to seek the help of a child care doctor and a pediatric orthopedic doctor as soon as possible, find out the clues in time through a simple B-ultrasound examination, and seek further medical treatment.
Parents often think that joint dislocation can only be seen clearly by X-ray or even CT examination, but they are worried that these examinations will cause too much damage to the newborn (radiation damage).
Here, Director Li Xu reminds that all babies within 4 months can be screened with safe, non-invasive and radiation free B-ultrasound, and for children with hip dislocation, B-ultrasound alone is enough.
Slight "O leg" within 2 years old is normal
Many mothers are concerned about whether "genu varus" or "O leg" is calcium deficiency. Li Xu introduced that the growth of most children needs to go through a special process: before the age of 2, most children will have mild genu varus, that is, O-shaped legs, and correct themselves when they are 2 years old; However, at the age of 2-4 years old, they gradually became X-shaped legs, and gradually corrected themselves after the age of 4 years old. After the age of 6 years old, most people had slight genu valgus.
Li Xu suggested that children should take vitamin D supplements every day and drink milk when they are born in primary school. According to research, children from kindergarten to primary school need 500 ml of milk every day to provide enough calcium for bone growth.
In the past, due to the lack of understanding of diseases, in many cases, children's bone problems, even diseases requiring surgical treatment, are attributed to calcium deficiency. In fact, as long as children eat a balanced diet, they will not suffer from calcium deficiency.
If there is no clear medical evidence to prove calcium deficiency (such as abnormal blood calcium index), it is not necessary to supplement calcium through calcium tablets, and parents are opposed to blindly taking drugs to supplement calcium without the guidance of doctors.
O-shaped legs can be straightened with braces before the age of 6
As for the "O leg" problem of children of all ages after the age of 2, Li Xu said that it can be roughly judged whether they need to see a doctor according to their age and the severity of genu varus. It should be reminded that normal children learn to walk between 12 months and 18 months, and it is normal that they can walk 10 months earlier, but parents should not deliberately let children learn to walk too early. Because if the baby's skeleton has not grown to the stage where he can walk, he will stand and bear weight too early, which is more likely to cause "O leg".
If the children's genu varus and genu valgus are too obvious, it is likely to be pathological, but it is difficult for ordinary parents to distinguish this situation, which requires professional diagnosis by pediatric orthopedic doctors.
It should be noted that the degree of genu varus in some children has seriously affected their beauty, but from a medical point of view, it has not reached the level of pathological manifestations.
In this case, children can be treated by wearing orthopedic shoes and braces before they are six or seven years old. Generally, children over six or seven years old have hard bone development and can not be completely corrected by simply wearing orthopedic shoes or braces, which may require further evaluation by children's orthopedic doctors, See if surgery or other more active corrective treatment is necessary. Therefore, if parents feel that the child's situation needs further treatment, they should consult the pediatric orthopedic doctor as soon as possible.
Don't wear shoes if you want your baby to be healthy and barefoot
As for the factors affecting the healthy development of lower limbs, Director Li Xu put forward the following points in view of the problems raised by fans: first, for children's interests, playing football does not lead to "O" legs; Second, ballet practice requires standing on tiptoe for a long time, which is not good for developing children; Third, the correct approach to the healthy development of children's lower limbs is to start from the children's learning to walk and let the children move barefoot as far as possible. Research shows that children with more barefoot activities are less likely to have flat feet than children with more shoes.
Shoes mainly play a protective role for children, such as preventing skin scratches and reducing the formation of calluses (calluses). In general, good shoes need to have the following characteristics: first, the upper is hard enough to prevent deformation; second, the height of the shoe waist is high enough to protect the ankle; third, the soles are moderately soft and hard, preferably slightly hard, and the soles have arch radians, which is conducive to the development of the arch of the foot.
Many people like to use walkers and walkers for toddlers, which is not necessary for normal children, but for children with stunted growth, they can use walkers and walkers to help. It is not all bad for children to fall a few times in the process of learning to walk. (Reporter Zhou Jieying, Correspondent You Hualing)
