The treatment outcomes at patients with degenerative dystrofic diseases of cervical and lumbar spine underwent surgery with usage of dynamic spinal implants

Abstract

The rigid fusion of vertebral column leads to pathological redistribution of loads on the spine and to development of adjacent level syndrome. The dynamic implants, which allow saving the mobility in operated spinal motion segment, are placed to prevent the development of such complication. Objective: to estimate the surgical treatment outcomes at patients with degenerative-dystrophic diseases of cervical and lumbar spine who underwent the placement of dynamic implants. Materials and methods: We operated 70 patients suffered from degenerative-dystrophic spinal diseases, who underwent the placement of various dynamic implants («DCI», «Endocarbon” and “M6” in the cervical level; «Coflex», «DIAM», «Interspinal U», «Cosmic-mia» and «Legacy» at the lumbar level) from 2008 till 2013 in Scientific Research Institute of Emergency Care n.a. N.V. Sklifosovskiy. Results: all implants in lumbar spine remained dynamic in delayed postoperative period, but not all implants at the cervical level continued to play their dynamic role partly because of developing of spondylodesis in case of new bone tissue formation in dynamic cages.
