Outcomes
Primary Outcome Measures
visual analog scale
visual analog scale(0-10 scores) is for pain, 0 represent no pain, 10 score represent the severe pain.
Oswestry Disability Index
Oswestry Disability Index is for movement function, Questionnaire examines perceived level of disability in everyday activities of daily living. The ODI score (index) is calculated as: For example: If all 10 sections are completed, the score is calculated as follows: if 16 (total scored) out of 50 (total possible score) x 100 = 32%; If one section is missed (or not applicable), the score is calculated: If 16 (total scored) / 45 (total possible score) x 100 = 35.5%.
Intervertebral height
Intervertebral height in X-ray is for recontruction of the intervertebral space.
Range of motion(ROM)
ROM was measured by the flexion-extension radiographs of both endplates of the treated segment.

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