Scoliosis: The structural scoliosis subtype commonly seen in adolescents is “adolescent idiopathic scoliosis. It is defined as a scoliosis and rotational deformity of the spine in the three-dimensional plane without congenital spinal anomalies or comorbid neuromusculoskeletal disorders. The etiology of AIS is still unclear, and the associated factors include hormonal, genetic, neuroendocrine system abnormalities, or neurosystemic balance dysfunction. Scoliosis is detected in 70-80% of adolescents. According to the screening results in recent years, the incidence of scoliosis among adolescents in Shenzhen is close to 6%, while the global incidence of scoliosis is 1%-3%, indicating that the spinal health of adolescents in Shenzhen needs urgent attention. Do not think that scoliosis only affects the appearance, serious may compress the spinal cord or nerves, leading to hemiplegia, and even shorten life expectancy due to serious impairment of cardiopulmonary function. 1, idiopathic: the most common, accounting for 75% to 85% of the total, the cause of the onset is not clear, so called idiopathic scoliosis. According to the age of onset, it can be divided into three categories. (1) Infant type (0 to 3 years old) ① natural healing type; ② progressive type. (2) Juvenile type (4 to 10 years old) (3) Juvenile type (>10 years old to skeletal maturity). Among the above three types, the adolescent type is the most common. 2, congenital: (1) poorly formed ① congenital hemivertebrae; ② congenital cuneiform vertebrae. (2) poorly segmented type. (3) Mixed type, combining both of these types. Congenital scoliosis is caused by incomplete segmentation of the spine during the embryonic period, a bone bridge on one side or incomplete development of one vertebra or a combination of both of these factors, resulting in asymmetric growth on both sides of the spine, resulting in scoliosis. It is often combined with other deformities, including spinal cord deformity, congenital heart disease, and congenital urinary tract deformity, and the spinal developmental deformity is usually detected on X-ray.
