Scoliosis is a condition in which there is an abnormal curvature of the spinal vertebrae. The Scoliosis Research Society (SRS) states that the diagnostic criteria for scoliosis is a spine with a Cobb’s angle greater than 10° measured in the coronal plane. Scoliosis is classified as congenital, neuromuscular, and idiopathic. In general, congenital scoliosis is caused by abnormal embryonic development of the spine; idiopathic scoliosis means that the cause is still unknown; neuromuscular scoliosis is secondary to various neuromuscular diseases, such as spinal cavitation, poliomyelitis, and cerebral palsy. Therefore, scoliosis patients especially need to be checked for spinal cord disease before treatment so that the diagnosis and treatment of etiology such as spinal cavernous disease is not missed. According to our specialist, specialized websites and professional databases, patients with spinal cord cavitation often develop scoliosis deformity. Due to the combination of muscle atrophy in patients with spinal cord cavitation, it can lead to muscle imbalance on both sides of the spine and most scoliosis protrudes to the side with muscle atrophy. Some studies have reported that the incidence of scoliosis in patients with spinal cord cavitation can be as high as 60% or more. In principle, scoliosis in combination with spinal cavitation should be treated first for spinal cavitation, and scoliosis correction should be considered after the spinal cavitation is controlled. According to our experience and literature, scoliosis is expected to be controlled and improved in patients with mild scoliosis after spinal cavitation treatment. After 1-3 years of spinal cavitation surgery, if scoliosis is found to be aggravated or if there is a request for plastic surgery, scoliosis plastic surgery will be considered again. Special emphasis is placed on the treatment of adolescent scoliosis patients with combined spinal cavities. Scoliosis is the occurrence of abnormal curvature of the spine and is commonly seen in rapidly growing adolescents. In children, scoliosis may be detected by an MRI when the spinal cord is examined for cavitation. A very clear treatment principle is that specialist treatment for spinal cavitation is needed before surgery to correct scoliosis.
