Lumbar Dynamic Minimally Invasive Stabilization with Dynesys System Through Wiltse Far-Lateral Approach: A Surgical Alternative to the Open Surgery in Case of Failure of Interspinous Posterior Device

Alessandro Landi, Nicola Marotta, Fabrizio Gregori and Roberto Delfini

The dynamic stabilization, actually defined as dynamic neutralization of instability, represents a valid surgical choice in that condition defined as unstable dysfunction phase of the degenerative cascade of lumbar spine (or so called “microinstability”), provided that there is not a spondylolisthesis in the spinal segment involved. The pedicle dynamic stabilizations system DYNESYS is the one who respects the most the biomechanical characteristics of the spine. We describe our experience in a patient in which we used the DYNESYS system through a minimally invasive far lateral lumbar approach (Wiltse approach), as a rescue technique of the segmental motility after the failure of an interspinous posterior device, as an alternative to the classical open approach.
