About

To explore the clinical outcomes of discectomy with dynamic neutralization system(Dynesys) on treatment of single-segmental lumbar disc herniation(LDH) versus simple discectomy.

Full description

The study was to explore the clinical outcomes of discectomy with dynamic neutralization system(Dynesys) on treatment of single-segmental lumbar disc herniation(LDH) versus simple discectomy. 128 patients with single-segmental LDH were randomly divided into discectomy with Dynesys group(group A) and simple discectomy group(group B). Both groups were evaluated by Visual Analogue Score(VAS), Oswestry Disability Index(ODI), radiological evidence of intervertebral height and range of motion(ROM) of the treated segment at pre- and post-operation. Operation duration and blood loss was recorded. The clinical outcomes and complications were evaluated afterwards. All patients received a 2-year follow-up.
