The overall treatment plan for spinal disorders such as degenerative disease, cervical spondylosis, lumbar disc herniation, spinal stenosis, and vertebral slippage is decompression, fixation and fusion, and structural reconstruction. Decompression is the removal of nerve-compressing discs, enlarged joints, ligaments, bone spurs, and slipped vertebrae to be repositioned. Since the degenerated spine is inherently unstable and decompression surgery adds to the instability of the spine, some patients require internal fixation surgery to fix the decompression site with plate screws and other materials, as well as bone grafting to fuse the diseased segment with the upper and lower segments in order to achieve long-term stability. However, if the nerve has been compressed for a long time and degenerative damage has occurred, some symptoms such as numbness of the limb may remain after surgery.
