| Secondary study design | Randomised controlled trial |
| Scientific title | The Sciatica-PLDD trial: a prospective randomised controlled efficiency and efficacy trial on percutaneous laser disc decompression as a treatment modality for sciatica caused by a lumbar disc herniation |
| Study objectives | Percutaneous laser disc decompression (PLDD) is more cost-effective than conventional surgical treatment for lumbar disc herniation and allows faster patient rehabilitation, while long-term functional results are comparable. |
| Ethics approval(s) | Ethics approval received from the local medical ethics committee |
| Health condition(s) or problem(s) studied | Sciatica |
| Intervention | Patients who fit the inclusion and exclusion criteria for the trial for lumbar disc herniation will be randomised into two groups: 1. The first group will receive microsurgical discectomy in their own hospital 2. The second group will be referred to 1 of 4 assigned PLDD-centers, where percutaneous laser disc decompression will be carried out by an experienced interventional (neuro-)radiologist |
| Intervention type | Other |
| Primary outcome measure(s) |
Roland Disability Questionnaire for Sciatica |
| Key secondary outcome measure(s) |
1. A cost-effectiveness-analysis will be carried out on the basis of health-related utility factors. This will include costs of sickness absence and long-term disability. |
