Examine Design: Retrospective research with long-term follow-up.
Function: To judge the long-term incidence of adjoining section degeneration (ASD) and medical outcomes in a consecutive collection of sufferers who underwent spinal decompression related to dynamic or hybrid stabilization with a Flex+TM stabilization system (SpineVision, Antony, France) for lumbar spinal stenosis.
Overview of Literature: The incidence of ASD and medical outcomes following dynamic or hybrid stabilization with the Flex+TM system used for lumbar spinal stenosis haven’t been nicely investigated.
Strategies: Twenty-one sufferers with lumbar stenosis and possible post-decompressive spinal instability underwent decompressive laminectomy adopted by spinal stabilization utilizing the Flex+TM stabilization system. The indication for a mono-level dynamic stabilization was a preoperative magnetic resonance imaging (MRI) demonstrating proof of extreme disc illness related to extreme spinal stenosis. The hybrid stabilization (rigid-dynamic) system was used for multilevel laminectomies with related preliminary degenerative scoliosis, first-grade spondylolisthesis, or rostral pathology.
Outcomes: The advance in Visible Analog Scale and Oswestry Incapacity Index scores at follow-up have been statistically important (p<zero.0001 and p<zero.0001, respectively). On the 5-Eight-year follow-up, medical examination, MRI, and X-ray findings confirmed an ASD complication with ache and incapacity in one among 21 sufferers. The medical outcomes have been related in sufferers handled with dynamic or hybrid fixation.
Conclusions: Sufferers handled with laminectomy and Flex+TM stabilization offered a passable medical consequence after 5-Eight years of follow-up, and ASD incidence in our collection was four.76% (one affected person out of 21). We’re conscious that this can be a small collection, however our long-term follow-up could also be enough to contribute to the increasing physique of literature on the event of symptomatic ASD related to dynamic or hybrid fixation.
