Thoracic scoliosis is a spinal deformity in which one or more vertebral segments of the spine are bent to the side with vertebral body rotation. Thoracic scoliosis has a high incidence in the modern population and affects a wide range of people at a progressively younger age. In milder cases, patients may experience fatigue and weakness, shoulder and back pain, and difficulty concentrating, while in severe cases, in addition to the above symptoms, patients may experience severe back pain and limited movement of the thoracic spine. Severe scoliosis of the thoracic spine in adolescents can also affect the development of internal organs, and those with functional impairment should be treated with surgical correction. It has many causes, the most common of which is long-term unilateral shoulder weight, long-term incorrect posture, unilateral movement resulting in uneven muscle tightness on both sides of the thoracic spine, and compensatory scoliosis of the thoracic spine caused by pelvic tilt. In addition, other things such as heavy blows from external forces, as well as car accidents and collisions, can also cause compression of the thoracic spine nerves, resulting in diseases of the thoracic organs. Treatment should first be active conservative treatment, using physical therapy traction, closed treatment, etc., and when there is dysfunction is required to correct surgery.
