Why do you get scoliosis? There are many causes of scoliosis, which can be broadly classified as congenital or acquired.
Congenital refers to the abnormal development of the crest during the fetal stage before birth. The critical period of crestal development during the embryonic period is the 5th and 6th weeks of gestation, which is the time when the crestal segmentation occurs. If the fetus is affected by drugs, viruses, and physical and chemical factors during this period, it is prone to crestal developmental malformations. In contrast, acquired scoliosis often occurs in adolescence, mostly after the age of 10 years.
The causes of scoliosis in adolescents are not known, but in general it does not occur simply because of improper sitting and sleeping postures or incorrect backpacking.
Rather, there are more intrinsic causes, related to developmental abnormalities, neuromuscular imbalances, endocrine disorders, or impaired homeostasis. There is no way to predict who will develop adolescent scoliosis and who will not. Is scoliosis hereditary? Although some patients have a family history of scoliosis, the vast majority of patients do not pass the scoliosis on to the next generation. Is there a high incidence of scoliosis? The prevalence of scoliosis is not low, about 3%, or 3 out of every 100 people. What is this concept? It means that if you look at 200 people on the street, one in 200 people will have scoliosis.
Or if there are 300 people in your child’s grade, if they all go for screening, they can find almost 10 people with scoliosis.
But why do we all think we rarely see people with scoliosis? This is because although the prevalence of scoliosis is not low, as high as 3%, the majority of cases are mild.
Scoliosis is generally only visible when wearing tight clothing when it is over 30 degrees, and it is generally only visible when wearing less tight clothing when it is over 40 degrees.
The incidence of scoliosis above 40 degrees is much lower, at about 3 in 1,000. Is there a difference in the incidence of scoliosis between men and women? Congenital scoliosis is more common in boys, with a male to female ratio of about 4:1, while acquired scoliosis, or adolescent idiopathic scoliosis, is significantly more common in girls than boys, especially in patients with a curvature of more than 40 degrees.
Girls account for more than 90% of patients with a curvature of more than 40 degrees. Why is the incidence of girls so higher? Now the cause of its onset is not particularly clear, until now we are still studying the problem, but it is true that there is such a phenomenon, the incidence of girls is high, which shows that the genes in the onset of idiopathic scoliosis or have a certain role.
