When it comes to children's foot varus, it is a very common sign in pediatric orthopedics, commonly known as clubfoot. Its cause is not closely related to the bones, but to the abnormal development of tendons and ligaments.
Where does clubfoot come from? Some children can be diagnosed with clubfoot through B-ultrasound in the second and third trimester of pregnancy before they are born. This means that it is probably not an embryonic malformation, because it is almost not seen in B-ultrasound during the first trimester.
Clubfoot has appeared.
The general medical explanation is that clubfoot occurs when the mother is pregnant, and the child changes from a normal foot to a clubfoot. The reason may be that the fetus is in an incorrect position or the fetus is too large, and the child is compressed in the mother's uterus, causing the foot to deform.
.Since medical science cannot completely determine the only cause, and other causes cannot be ruled out, doctors have been investigating whether genetic and other factors may cause abnormal foot pronation during the development of children.
Clubfoot, like other diseases, may be a simple congenital foot deformity, or it may be a symptom secondary to other diseases. The most common secondary disease among other diseases is neurosurgical disease, and neurosurgical diseases include
Nervous central system diseases and peripheral nervous system diseases. Nervous central system diseases are problems with the brain and spinal cord. This is a major matter and requires careful examination and identification by a doctor.
Neurosurgical examinations in pediatrics are similar to those in adults. They examine the child's state of consciousness and examine various shallow and deep reflexes. The only difference between children and adults is that infants and young children are still growing and developing, unlike adults who have completed development.
This leads to the fact that the child's head is not fully grown at birth. The brain will continue to develop after the child is born, and the head will gradually become larger along with the development of the entire body, which is reflected in the normal physiological range of head circumference.
Measuring head circumference is a routine item in the normal physical examination of infants and young children. Emergency re-examination is mainly to prevent children from sudden diseases, and some parents are careless and do not take their children for physical examination on time.
By measuring the head circumference, we can know that the child's brain is developing, and the brain must expand outward during the development process. In order to meet the needs of growth in this area, human physiological structure deliberately does not close all the cranial sutures immediately after birth, but waits for the child to
When the brain is developed, the entire skull will grow together to form the strongest helmet to protect the brain. Because of this, before the skull grows together, the head of an infant is much more fragile than that of an adult. Once a trauma occurs to the brain of an infant, it can be imagined that
It is very serious to be informed that it is heavier than an adult.
Before several skull bones grow together and close, the gap area left between them is like a temporarily opened door, so it is called a fontanel. There are two such fontanels, one is in the front center of the child's head, diamond-shaped,
It is the anterior fontanel, which needs to be completely closed until the child is one to one and a half years old. The posterior fontanel is the triangular shape at the back of the head. Some children are already closed when they are born, and the latest it can close is six to eight weeks.
Sometimes we can see clinically that the child's head seems to be deformed when he is born. This is mostly due to the fact that the anterior fontanel is not closed. There is no need to be nervous. It will grow back naturally after it closes. Experienced elderly people say that it is when the front fontanel is born.
It is not entirely unreasonable to say that the child has a pointed head squeezed out by the mother. Because the baby's unclosed fontanel is also an adjustment for the baby's head to adapt to the changes in the mother's birth canal, making it easier for the mother to give birth smoothly.
