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.

Design outcomes

Primary

MeasureTime frameDescription
Oswestry Disability Index2 yearOswestry 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%.
visual analog scale2 yearvisual analog scale(0-10 scores) is for pain, 0 represent no pain, 10 score represent the severe pain.
Intervertebral height2 yearIntervertebral height in X-ray is for recontruction of the intervertebral space.
Range of motion(ROM)2 yearROM was measured by the flexion-extension radiographs of both endplates of the treated segment.
