The consequences of not having surgery for severe scoliosis need to be considered based on two aspects. If the patient is young, severe scoliosis may progress further as he or she grows, which can affect cardiopulmonary function and even be life-threatening, leading to respiratory and circulatory failure. In contrast, in adults with severe scoliosis, if they are in a more stable state, they can sometimes continue to be observed. However, with further age, when osteoporosis and scoliosis are further aggravated, there will also be cardiopulmonary effects, which can be life-threatening, so surgery is generally recommended for severe scoliosis. In children, as they grow and develop, there is a risk of further aggravation, which can cause the development of cardiopulmonary function and can be life-threatening. In adults with severe scoliosis, there are corresponding cardiopulmonary problems as they age and may be in a compensatory phase. When the age is too old, osteoporosis occurs and further compensatory function decline occurs, at which time abnormalities in cardiopulmonary function can also occur.
