Dynamic fixation of the lumbar spine dynamic fixation of the lumbar spine

Abstract

The review of modern literature data on the use of dynamic fixation in degenerative diseases of intervertebral discs and facet joints of the lumbar spine is presented. The frequent cause of temporary loss of working ability and primary disability, poor results of conservative treatment for degenerative changes in the lumbar segments stipulate the high medical and social significance of this problem. Quite often the use of classical decompression techniques and rigid fusion does not eliminate clinical symptoms on account of pseudarthrosis formation in the operated segment and significant degeneration development in the adjacent one. The use of dynamic implants is aimed at restoring spatial segmental relationships with the preservation of natural biomechanics of the spine. Taking into consideration the variety of constructions and the high rate of their introduction into practice, the literature data present conflicting information on the results of their application. The authors expound modern data on the clinical results and instrumental potentialities of various dynamic devices application. The topical unsolved issues that necessitate the conduction of long-term multicenter clinical studies on the management of this pathology are identified.
