Dynamic Lumbar Stabilization with Peek Rod/Titanium to Prevent Adjacent Disc Pathology

Over the last decades segmental spinal fusion has become the standard surgical procedure for lumbar degenerative spondyloarthropathy [1]. Its evolution towards the most modern instrumentation techniques has achieved a very high percentage of success in spinal fusion in the lumbar region [2]. This varies between 72 and 91%, depending on the technique used. But the success of lumbar fusion has been seen to be accompanied by the appearance of what is known as adjacent segment disease [3]. These pathological changes, which may appear in the disc above or below the fusion as degenerative disc disease [4-7], segmental instability or spinal stenosis, have high prevalence and reoperation rates. Spinal fusion resulting in the increase of intradiscal pressure (IDP) on the adjacent segment has been pointed at as being the etiopathogeny of this syndrome.
