Evaluation of Outcomes of Discectomy With Dynesys in Treatment of Lumbar Disc Herniation

Evaluation of Outcomes of Discectomy With Dynesys in Treatment of Lumbar Disc Herniation: a Prospective Study

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

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.

Inclusion Criteria:

Inclusion criteria was Single-segmental LDH with low back pain and radicular pain.

Exclusion Criteria:

Exclusion criterias were lumbar stenosis(LSS), lumbar spondylolysis and degenerative spondylolisthesis, spinal deformity, lumbar surgery history, obviously osteoporosis, vertebral fracture, cauda equina syndrome, ankylosing spondylitis, tuberculosis, infection, tumor, obesity.
