Numbness in the hands and feet of cervical spondylosis is mainly seen in nerve root type cervical spondylosis, due to compression or stimulation of nerve roots, resulting in sensory hypersensitivity or impaired movement and reflexes in the corresponding nerve distribution areas. It is recommended to do cervical spine MRI to clarify the location and severity of nerve root compression, and to do cervical spine traction belt or wear a cervical brace to do cervical spine braking and do some physical therapy to relieve the symptoms of cervical spondylosis hand and foot numbness. If the cervical nerve root compression is very serious and there is no obvious relief through conservative treatment, surgery should be done if necessary, and nerve decompression surgery can be done to remove the root cause of nerve compression. If the nerve root compression is caused by a prolapsed or herniated nucleus pulposus, the nucleus pulposus should be removed. If the nerve root compression is caused by the formation or loosening of the bone spur of the hook spine joint and the instability of the cervical spine, some surgery on the bony structure may be required to rebuild the stability of the cervical spine, and if necessary, the fusion of the hook spine joint should be fixed to remove the bone spur, so as to cure the cervical spondylosis of the nerve root type.
