Scoliosis is a serious cause of a seven-centimeter difference between the short and long legs, and should be treated first. Commonly used methods include orthopedic therapy, exercise therapy, and surgical treatment. 1. Orthopedic treatment: The orthopedic brace utilizes the “three-point force” system, which applies pressure on the convex side of the spine and releases it on the concave side, pushing the convex side toward the concave side, thus achieving the purpose of orthopedic treatment. 2. Exercise therapy: Exercise can improve the flexibility of the spine and strengthen the muscles of the lower back, which in turn can correct scoliosis. It is mainly applied to early scoliosis patients, and the sports programs include swimming and hanging bar. 3. Surgery: For adolescent scoliosis or rigid congenital scoliosis, scoliosis angle is large, or physical therapy and drug treatment is ineffective scoliosis patients, you can use surgical treatment, such as posterior surgery. Then there is surgical treatment for long and short legs. A common surgical method is osteotomy and lengthening, in which the tibia and fibula are cut off and slowly lengthened to the appropriate length, and then an external fixation frame is used to maintain the length, and the external fixation frame can be removed after complete recovery for rehabilitation training. It is recommended that patients with scoliosis-induced short and long legs go to the hospital in time for treatment and rehabilitation training under the guidance of the doctor.
