Before scoliosis surgery the stage of surgery needs to be decided according to the patient’s scoliosis, whether it is from the thoracic to the lumbar spine, or simply the thoracic spine, or simply the lumbar spine. The surgical plan needs to be developed in conjunction with the patient’s films, and the specific surgical steps can be divided into three steps, as follows: 1. The first step is to cut the patient’s skin and subcutaneous, thereby completely loosening the muscles. For patients with scoliosis, anesthetic drugs as well as muscle relaxation are very important, relaxing the muscles through anesthetic drugs and stripping the muscles through surgery so that the patient’s bony structures are fully relaxed, and for scoliosis many times 30%-40% relaxation and relief has been achieved; 2. The second step is to implant the pedicle screws; 3. The third step is to use a nail bar, and the purpose of using a nail bar is to allow the nail to be re-entered alignment combination. And the first step is very important, the spine is loosened after the release, and then the nail rod is used after the release by hitting the nail, thus allowing the spine to get rearranged between each nail, so that the spine becomes straight from the curved state.
