FIELD: medical engineering; surgery. SUBSTANCE: apparatus comprises rod 1 carrying supporting elements 2, 3. and sleeves 4 interposed between supporting elements, and sleeve length is multiple to distance between arches of vertebrae. Treatment is highly effective due to increased number of support points, whereby stability of whole structure is improved. EFFECT: reduced probability for fractures of arches of support vertebrae; reduced risk for neurologic complications. 1 dwg
