What causes scoliosis? Some patients are born with this problem, some have spinal curvature caused by cerebral palsy, and idiopathic scoliosis accounts for about 75-80% of clinical cases. Some studies have suggested that there may be a genetic relationship, and a multifactorial one at that, but it is not clear exactly which gene or DNA change causes scoliosis. When does scoliosis develop? What is the incidence rate? Generally, the incidence of scoliosis is about 1-3%. The prevalence rate of scoliosis is about 1.5% in surveys conducted in different parts of China, including Tianjin and Guangdong, with some reporting 1.7%, some 2%, and the overall rate is about 1.5%. Generally, there is a measurement of the degree of scoliosis, if more than 10 degrees is defined as scoliosis, counted in 1.5%, if 20 degrees is more prevalent, the prevalence is about 0.1% to 0.2%. At what age is the treatment more effective? It is difficult to determine when scoliosis will develop. The growth spurt occurs between the ages of 0 and 3 years, and the second spurt occurs between the ages of 10 and 16 years, and may occur earlier in girls. During this growth spurt, scoliosis develops more rapidly, so more patients are operated on during this period. The decision to operate is based on the size of the scoliosis, and the decision to treat or not to treat is also based on the size of the scoliosis and the rate of progression. Currently, a more objective method is based on follow-up. How does early detection and treatment of scoliosis help later outcomes? Most scoliosis, such as those that require bracing, can be controlled, and in some cases surgery can be avoided.
