Summary
Computed tomography (CT) fluoroscopy-guided selective nerve root block (SNRB) effectively treats severe arm pain from acute cervical disc herniation. This minimally invasive procedure offers significant pain relief and improved function in most patients.
Area of Science:
- Neurosurgery
- Pain Management
- Radiology
Background:
- Acute cervical disc herniation frequently causes severe arm pain.
- Conservative treatments are sought for pain relief and functional improvement.
Purpose of the Study:
- To evaluate the clinical outcomes of CT fluoroscopy-guided selective nerve root block (SNRB) for severe arm pain.
- To assess the efficacy of SNRB as a primary conservative treatment.
Main Methods:
- 25 patients with severe arm pain (VAS ≥ 8) due to acute cervical disc herniation underwent CT fluoroscopy-guided SNRB.
- Patients with chronic pain, motor weakness, or hard disc herniation were excluded.
- Outcomes were assessed using Visual Analogue Scale (VAS) and Neck Disability Index (NDI) at a mean follow-up of 11.5 months.
Main Results:
- Mean VAS and NDI scores significantly improved from 9 and 58.2 to 3.4 and 28.1, respectively.
- 72% of patients (18/25) achieved successful clinical outcomes.
- No procedure-related complications were reported.
Conclusions:
- CT fluoroscopy-guided SNRB is a safe and effective treatment option for severe arm pain caused by acute cervical disc herniation.
- SNRB may serve as a valuable primary conservative therapy, potentially reducing the need for surgery.
