ROCHA, Ivan Dias; CRISTANTE, Alexandre Fogaça  and  MARCON, Raphael Martus. Lumbar dynamic stabilizations. Coluna/Columna [online]. 2012, vol.11, n.1, pp.77-80. ISSN 1808-1851.

The normal physiological functioning of the spine depends on the normal movement of each motor unit, which consists of two vertebrae and the intervertebral disc interposed between them. Although fusion of a spine motor unit may be used to treat various diseases of the spine, this modality of treatment results in loss of movement of the levels that were fused and consequently may overload the adjacent levels and may cause its degeneration. Proponents of dynamic stabilization techniques believe that it may lead to correction of problems minimizing the risk of degeneration of adjacent levels. Currently there are different market dynamic stabilization methods. Already there are biomechanical studies that prove the theoretical benefit of almost all of them, but it is still missing clinical trials to prove its usefulness and safety for long periods of follow-up to the patient. It is therefore essential that these materials are considered for prospective clinical trial with long period of follow up so that in the near future they may be used precisely and safely to patients.
