Paralytic: scoliosis caused by a variety of reasons on both sides of the trunk muscle imbalance atrophy or loss of function, paralytic scoliosis can occur, the most common in our country is due to poliomyelitis caused. The curvature of paralytic scoliosis is determined by the size of muscle strength, the scope of imbalance caused by muscle paralysis and secondary contracture. Typical paralytic scoliosis is a long curvature of the thoracic segments. The scoliosis improves significantly when lying down, and in severe cases, the tension of the lumbar trunk muscles can be completely lost, causing the lumbar spine to form an extensive movable curvature, and lumbar paralysis often occurs, with the patient unable to get up and sit down, and losing the ability to work and take care of himself. Congenital: this type of scoliosis is not uncommon, second only to idiopathic scoliosis, the cause of which is still unclear, and the 4th to 7th week of gestation, by the mother’s internal and external environmental changes in the stimulation of the postnatal deformity signs, but due to the lack of diagnostic knowledge and diagnostic means, the lesion is often overlooked by the parents and doctors until the development of the deformity is obvious, and then be detected. Neuromuscular: This type of scoliosis is caused by known neuromuscular lesions, such as upper motor neuron injury lesions: cerebral palsy, and spinal deformity after high spinal cord injury in childhood. There are also scoliosis due to lower motor neuron injury: the most common are post-polio scoliosis, spinal bulge, etc. and lesions of the muscles themselves can also occur, such as progressive muscular dystrophy. The indications for surgical treatment are: scoliosis is aggravated, cardiorespiratory function is affected, unable to maintain sitting posture without using hands, obvious pelvic tilt, lumbar spine collapses, the quarter rib tops the iliac crest, which causes localized pain, or there is a serious lumbar anterior protruding deformity and lumbago, and so on.
