FIELD: medicine; medical engineering. SUBSTANCE: method involves building penetrating slot between adjacent vertebrae with disk hernia being removed. A portion of bone tissue is removed from the vertebral bodies and the appeared cavity is filled with auto bone and covering plate is attached to anterior surfaces of adjacent vertebrae. Crushed deleted bone tissue taken off from the vertebral bodies is applied as autobone.
