γγThe spine of a normal person is straight from the back, and when standing in the front and back position, the shoulders should be parallel and equal, and the body straight. As the longitudinal axis of the human body, the spine should be as vertical as a plumb line, vertical on the central axis. Whether in the standing position, or bending forward, from behind should see the back profile of both sides of the spine flat and symmetrical, if the shoulders are not equal, the back is not flat, the spine deviates from the central axis, there may be scoliosis problems. In short, a normal standing person, observed in the front and back position, whose spine deviates from the central axis, is called scoliosis, also known as scoliosis. The type of scoliosis is often divided according to the cause and can be divided into: 1, idiopathic scoliosis: this type of scoliosis is the most common, accounting for about 85% of the total number of patients with scoliosis, the exact cause is not clear. The onset of the “female light male” phenomenon, that is, the prevalence of women, the ratio of men to women is about 1:4. It is divided into three categories: infantile scoliosis (0-3 years), early childhood scoliosis (3-10) years, adolescent scoliosis (> 10 years), especially the most common adolescent type.γγ2, congenital scoliosis: its common cause is vertebral dysplasia, such as hemivertebrae, cuneiform vertebrae, etc.; 3, acquired scoliosis: more types, common can be: 4, postural scoliosis: due to long-term body posture; 5, compensatory scoliosis: such as limb inequality or pelvic tilt caused by scoliosis; 6, neurogenic scoliosis: such as poliomyelitis, pediatric cerebral palsy, etc. Scoliosis caused by muscle imbalance on both sides of the trunk; 7, thoracic scoliosis: such as children with abscess chest or thoracoplasty caused by scoliosis; 8, traumatic scoliosis: due to trauma to the spine.
