Objective: The aim of this study was to analyze the impact of the Dynesys system on fixation-adjacent intervertebral discs. Methods: Thirty six patients with lumbar degeneration diseases, who were treated with the Dynesys neutralization system (DNS) and posterior fusion method, were followed up for an average of two years. The Oswestry disability index (ODI) score was applied to analyze the clinical effects. The Woodend classification and apparent diffusion coefficient (ADC) scores of Magnetic Resonance Imaging (MRI) were used to analyze the imaging performance. Results: The results of the 24 to 48-month follow-up examination revealed that the ODI scores of the patients improved significantly (P<0.05). The ADC value of the Dynesys group on the final follow-up was statistically significant compared with the preoperative ADC value (P<0.05), and the final ADC scores were significantly different between the two groups (P<0.05). Conclusions: Dynamic stabilization of posterior lumbar vertebrae with the Dynesys system may prevent and delay the degeneration of intervertebral discs at the fixed segments. © 2016, E-Century Publishing Corporation.

The present study aimed to evaluate the early effects of interspinous spacers on lumbar degenerative disease. The clinical outcomes of 23 patients with lumbar degenerative disease, treated using interspinous spacer implantation alone or combined with posterior lumbar fusion, were retrospectively studied and assessed with a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). Pre-operative and post-operative interspinous distance, disc space height, foraminal width and height and segmental lordosis were determined. The early effects and complications associated with the interspinous spacers were recorded. The surgical procedures performed with the in-space treatment were easy and minimally invasive. The VAS scores and ODI were improved post-operatively compared with pre-operatively. Significant changes in the interspinous distance, disc space height, foraminal width and height and segmental lordosis were noted. In-space treatment for degenerative lumbar disease is easy and safe, with good early effects. The in-space system provides an alternative treatment for lumbar degenerative disease.
