Scoliosis is a three-dimensional spinal deformity in which one or several segments of the spine are bent laterally with vertebral rotation. The classification of scoliosis is as follows: 1. Idiopathic scoliosis Scoliosis of unknown origin is the most common, accounting for about 75% to 80% of the total. According to its age of onset, it is divided into infantile type (0-3 years old), juvenile type (3-10 years old) and adolescent type (after 10 years old). 2. Congenital scoliosis is divided into three types according to the developmental disorders of the spine: (1) formation disorders, with hemivertebrae and cuneiform vertebrae. (2) poor segmentation, with unilateral undifferentiated formation of bony bridges and bilateral undifferentiated (blocked vertebrae bloc vertebrae). (3) Mixed type: both impaired formation and malsegmentation. Studies have shown that the majority of congenital scoliosis is progressive, with only 10-25% of patients not progressing. Therefore, such patients should not be allowed to develop and should be fused early. The SRS classifies neuromuscular scoliosis into two categories: neurogenic and myogenic diseases, of which neurogenic diseases include superior and inferior neuronal lesions. Riley-Day syndrome is a lower neuron lesion. Myogenic diseases include multiple joint contractures, myotonic dystrophy, fiber disproportion, congenital hypotonia, myasthenia gravis, etc. 4. Neurofibromatosis combined with scoliosis is highly hereditary, accounting for about 2% of the total number of cases. It is characterized by more than six coffee spots on the skin, and some have limited rubbery neuromas. The deformity continues to progress, even after surgery; the incidence of pseudarthrosis is high, often requiring multiple bone graft fusions and difficult to treat. 5, mesenchymal lesions combined with scoliosis Mafang’s syndrome and Edan’s syndrome are both mesenchymal lesions. About 40-75% of patients with Marfan syndrome have scoliosis. They are characterized by severe scoliosis, often with painful canker sores, pulmonary dysfunction, long and thin body shape, elongated fingers (toes), funnel chest, chicken chest, high hip arch, ligamentous laxity, flat feet, and aortic and mitral valve atresia. Edam’s syndrome is characterized by short neck. 6, osteochondral dystrophy combined with scoliosis, including bending deformation of dwarfism, mucopolysaccharidosis, spinal bone marrow dysplasia, etc. 7, metabolic disorders combined with scoliosis, such as rickets, osteogenesis imperfecta, homocystinuria, etc. 8, extraspinal tissue contracture leading to scoliosis, such as abscess chest or after burns, etc.
