Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Cold detection threshold (CDT) is measured using the standardised quantitative sensory testing protocol at 24 months of follow-up. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Pain, back specific function, work disability and patient's satisfaction are measured using the Oswestry Disability Index (ODI) and the Core Outcome Measures Index (COMI) at baseline, within 1 week, 2, 6, 12 and 24 months 2. Generic health status (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) is measured using EuroQoL-5Dimension (EQ-5D) at baseline, within 1 week, 2, 6, 12 and 24 months 3. Severity of depression and responsiveness to treatment is measured using the Beck Depression Inventory (BDI) at baseline, within 1 week, 2, 6, 12 and 24 months 4. Neuropathic pain components in patient with back pain are measured using the painDETECT questionnaire (PD-Q) at baseline, within 1 week, 2, 6, 12 and 24 months 5. Neurological status and the quality and quantity of current pain medication, including epidural injections and nerve block injections, are documented at baseline, within 1 week, 2, 6, 12 and 24 months 6. Sensory function is measured by Two-point-discrimination (2PD) at baseline, within 1 week, 2, 6, 12 and 24 months 7. Functionality is measured using the timed up and go test (TUG) at baseline, within 1 week, 2, 6, 12 and 24 months 8. Muscle force is tested by a manual muscle tester (MMT) at baseline, within 1 week, 2, 6, 12 and 24 months 9. Intraoperative problems such as surgery related- or device related complications and postoperative complications like re-operations, recurrent disc herniations, infection or bleeding are recorded continuously throughout the study period 10. Characteristics of disc herniation and sagittal alignment are measured using magnetic resonance imaging (MRI) at baseline, within 1 week, 2, 6, 12 and 24 months 11. Cytokinelevels and inflammation markers are measured using IL-6, IL-1b, TNFa, CRP and WBC at baseline, within 1 week, 2, 6, 12 and 24 months | — |
