Clinical use of a new technique for surgical treatment of patients with lumbar osteochondrosis is described. The technique consists in prosthetics of the disk changed with a combined prosthesis. 47 patients with the decrease of vertebral bone mineral density to 67-72 % of age-related norm have been operated on, and their condition was an absolute contraindication for using routine disk endoprostheses in case of the segment instability revealed. Good clinical results were achieved in all the patients when the new combined prosthesis was used, this was evidenced by the fact that all of them started their professional activity within the first year after surgery.
