However, after spinal fusion, the range of motion between vertebral segments will be relatively reduced, and the range of motion may be less flexible. The traditional spinal fusion surgery for the treatment of intervertebral disc is to remove the patient's intervertebral disc. The protruding cartilage is removed and inserted into the patient's bone to fuse the bone covering the two intervertebral discs. Because the bone will grow, the problem of autolysis will make the waist stiff in the future. However, if the implant is artificially opened, there will be degenerative diseases such as bone spurs. Therefore, the affected intervertebral disc is either removed or lost its function, and the patient's lumbar spine will become weak or stiff, which will easily lead to subsequent joint degeneration. That is to say, the traditional treatment method, after bone fusion, reduces the gravity and buffer of the supporting load of an intervertebral disc, and the stability is poor. For patients with high demand for exercise, although the pain is relieved, their mobility is poor.
