Summary
Fluoroscopically-guided cervical nerve root blocks (CNRB) offer limited long-term relief for cervical radicular pain. While some patients experience significant short-term pain reduction, CNRB is not a definitive treatment.
Area of Science:
- Neurosurgery
- Pain Management
- Interventional Radiology
Background:
- Cervical radicular pain significantly impacts quality of life.
- Non-surgical interventions are sought for managing this condition.
- Fluoroscopically-guided cervical nerve root blocks (CNRB) are utilized as a treatment option.
Purpose of the Study:
- To evaluate the long-term effectiveness of fluoroscopically-guided CNRB for cervical radicular pain.
- To assess pain relief levels at various time points post-procedure.
Main Methods:
- Retrospective analysis of 19 patients undergoing 21 CNRB procedures.
- Data collected on demographics, diagnosis, and imaging findings.
- Pain relief assessed using the Visual Analogue Scale (VAS) at baseline, 2 weeks, 2 months, and 6 months post-procedure.
Main Results:
- At 6 months, 57.1% of procedures showed minimal pain relief (VAS decrease < 20).
- 14.3% experienced moderate relief (VAS decrease 20-40).
- 28.6% achieved significant relief (VAS decrease > 40).
Conclusions:
- Fluoroscopically-guided CNRB demonstrates limited long-term efficacy for definitive treatment of cervical radicular pain.
- A subgroup of patients may achieve significant short-term pain relief.
- Further research into optimal patient selection and treatment protocols is warranted.
