1, spinal cord and nerve root compression caused by spinal cord-related diseases is an important cause of shoulder and neck pain, low back and leg pain. 2.At present, such diseases are treated by neurosurgery internationally, and minimally invasive and complete decompression are the advantages of neurosurgery. 3.Under the operating microscope magnification 15~40 times, the compression of the spinal cord and nerve roots by the prolapsed disc can be completely removed. 4.Microscopic can cut the tumor as completely as possible and reduce the damage to the spinal cord and nerve roots. 5.Patients with atlanto-occipital deformity and skull base depression combined with subcerebellar tonsillar herniation can undergo subdural decompression to completely relieve the compression. 6.And for patients with combined spinal cord cavity, the long-term results are good after complete decompression.
