Detailed Description
The study is designed as a prospective randomized controlled trial, using a two-group stratified block-randomization, evaluating the effect of adding the outcome of a diagnostic SNRB to surgical decision-making. Stratification will be based on the study site. Block size will be 4, 6, or 8 and in random order.
All patients referred to our departments with suspected radiculopathy and radiological evidence of root compression are eligible for inclusion. Patients will be randomized to either standard care or SNRB after the consultation. Results of the SNRB will be available to the surgeon before deciding finally whether to operate or not. Hence, the intervention adds the outcome of the diagnostic SNRB to the shared surgical decision-making.
Study outline:
Baseline:
Demographics, Oswestry Disability Index, Eq5D, SF-36, NRS-LP, and NRS-BP will be recorded
1-month follow-up after surgery: Oswestry Disability Index, Eq5D, SF-36, NRS-LP, and NRS-BP will be recorded
3-months follow-up after surgery: Oswestry Disability Index, Eq5D, SF-36, NRS-LP, and NRS-BP will be recorded
12-months follow-up after surgery: Oswestry Disability Index, Eq5D, SF-36, NRS-LP, and NRS-BP will be recorded
Randomization:
Using RedCap patients will be randomized to receive a SNRB as part of the pre-operative workup or to direct operation.
SNRB-procedure:
At Aarhus University, the SNRB will be performed using CT-guidance; at Private Hospital Moelholm, the SNRB procedure will be guided by fluoroscopy. Drugs used are omnipaque (0,2 ml), betamethasone (0,5 ml) and bupivacain (0,5 ml)
