1, waist protection is mainly to reduce the load of the upper body on the fused lumbar vertebrae, that is, to strengthen the stability of the affected vertebrae, but it should not be worn for too long, about one to two months. If the time is too long, it may cause disuse atrophy of waist muscles. Don't get out of bed for too long, pay attention to strengthening the functional exercise of back muscles.

2. Lumbar fusion and internal fixation is the basic surgical technique to treat lumbar diseases. Through anterior, anterolateral, lateral, posterolateral and posterior operations of the lumbar spine, bone grafting is implanted between intervertebral joints or fusion cages, facet joints and transverse processes, so that bone healing occurs between intervertebral joints of the lumbar spine, thus establishing and maintaining the stability of the lumbar spine.

3. Operate under general anesthesia. Cut the skin, peel off the muscle to the pedicle, and insert pedicle screws into the pedicle of the related vertebral body. Take out the intervertebral disc that compresses the nerve, enlarge the narrow nerve root canal to relieve the compression on the lumbar nerve root, then implant the intervertebral fusion cage (or implant the autogenous broken bone), and insert the pedicle screw connecting rod to tighten it. Finally, the suture is completed (the first layer sutures the deep fascia, the second layer sutures the subcutaneous layer and the third layer sutures the skin).
