Definition of scoliosis: Scoliosis (also known as scoliosis) is a three-dimensional spinal deformity in which one or more segments of the spine are bent laterally with vertebral body rotation. scoliosis is defined as a lateral curvature of the spine measured by the Cobb method on standing ortho-x-ray images if the angle is greater than 10°. There are many causes of scoliosis, including congenital, idiopathic, neuromuscular, and functional scoliosis, with idiopathic scoliosis being the most common. Clinical manifestations: Most people with scoliosis are long and thin, and may have the following manifestations: 1, when bending forward in an upright position, the back on both sides is not equal; 2, the neckline and shoulders are not level; 3, one side of the back is abnormally raised; 4, the girl’s breast development is not symmetrical; 5, the waist side of the crease; 6, both sides of the hip is not equal; 7, both sides of the lower limbs are not equal. Treatment: Indications for brace treatment: (1) mild scoliosis between 20 and 40°, infantile and early juvenile idiopathic scoliosis, occasionally between 40 and 60° can also be braced, adolescent type of scoliosis to more than 40°, brace treatment is not appropriate. (2) Children with immature bones should be treated with braces. (3) Two structural curvatures to 50° or a single curvature of more than 45° should not be treated with braces. (4) Scoliosis with combined thoracic pronation should not be treated with bracing. The brace can aggravate the anterior convexity deformity and further reduce the anterior-posterior diameter of the thoracic cavity. (5) Long segmental curvature, brace treatment effect, such as 8 segments of 50 ° scoliosis brace treatment effect is better than 5 segments of 50 ° scoliosis. (6) 40° or less flexible lumbar or thoracolumbar scoliosis, Boston brace effect is best. (7) Brace treatment is not recommended for uncooperative patients and parents. For patients with idiopathic scoliosis within 35° and Risser’s sign <= 2 degrees, the efficiency of brace treatment can be more than 75%.
