Many scoliosis patients as well as parents often ask the question – when is a good time for scoliosis patients to have surgery? This question is indeed of great concern to patients, and I will give a brief answer below. First of all, let’s talk about the indications for scoliosis surgery. Generally speaking, if the angle of scoliosis (Cobb’s angle) exceeds 40° and a certain degree of correction cannot be obtained by means of conservative treatment or if the angle of scoliosis is still increasing further, then surgery should be considered. Further progression of the scoliosis angle is defined as an increase of 5° or more in the angle of scoliosis in six months with proper bracing. Patients with scoliosis who meet these criteria require surgical orthopedics. Next, I will talk about when is the best time for scoliosis surgery? Generally speaking, the best age for surgical treatment of idiopathic scoliosis is 10-18 years of age. But there are some special circumstances that need to be explained. 1. If the patient is a girl, she should ideally receive surgery within 1 year after her first menstrual period. Because the onset of menstruation in girls indicates that they are entering a growth spurt, scoliosis is in a relatively rapid progression period. Many parents find that their child’s scoliosis angle increases rapidly at this time. This is the best time for girls with scoliosis to have surgery to correct the problem. Missing this period, scoliosis orthopedic up will be more difficult, the scope of surgery will increase, the more vertebrae are fixed and fused. 2, if the patient’s age is less than 10 years old, but the thoracic scoliosis angle has been greater than 40 ° or lumbar bending angle of more than 35 °, and in the case of wearing a brace scoliosis is still further aggravated, should also be operated on as soon as possible. 3, if the patient is congenital scoliosis, neuromuscular scoliosis, metabolic disorders combined with scoliosis, etc., surgery should be performed as soon as possible. Although the degree of deformity may not be too serious at this time, but because the spinal deformity of such scoliosis patients usually progresses faster, if not timely surgery, it will also delay the timing of surgery, resulting in future correction is not ideal. Before growth arrest, the patient’s spinal flexibility is significantly better than after growth arrest. Thus, if the patient receives surgery before growth arrest, the scope of surgery will be reduced and the scoliosis correction will be significantly better than in adulthood. So, can scoliosis be surgically corrected after adulthood? Generally speaking, the bones have stopped developing after adulthood, and the angle of scoliosis generally does not progress significantly. However, in cases where the scoliosis angle is greater than 40°, there is a possibility of continued progression. Therefore, surgery is also recommended, because as we age, the stress on the curved spine accelerates the development of spinal hyperplasia degeneration, and the complexity of surgery is increased by waiting to treat conditions such as spinal stenosis due to hyperplasia. In addition, some adult scoliosis patients develop low back pain, which is caused by spinal deformity, the effect of conservative treatment is often unsatisfactory, therefore, the emergence of back pain symptoms that significantly affect life and learning, is also an indication for surgery for scoliosis. Adults are less effective in correcting this than adolescents because of the stiffness of the spine.
