Summary
Facet joint injection therapy offers safe and effective relief for chronic low back pain. Repetitive injections every 3 months are recommended for sustained pain management.
Area of Science:
- Pain Management
- Interventional Pain Medicine
- Spinal Injections
Background:
- Chronic low back pain is a significant health issue.
- Facet joint injections are a practical therapeutic approach.
- Limited prospective studies exist with standardized protocols.
Purpose of the Study:
- Evaluate the quantity and duration of clinical improvement from a standardized facet joint injection protocol.
- Determine the optimal timing for repeat injections.
Main Methods:
- 39 patients with lumbar facet syndrome received standardized injections (steroids, local anesthetic, phenol) under fluoroscopic guidance.
- Follow-up utilized a custom questionnaire, MacNab criteria, visual analogue scale, and pain disability index.
Main Results:
- Pain reduction was observed for up to 6 months.
- 62% reported good/excellent outcomes at 1 month, decreasing to 36% at 6 months.
- No correlation found between age, BMI, or prior surgery and treatment outcomes; mild side effects were infrequent.
Conclusions:
- Standardized facet joint injection therapy is safe and effective for lumbar facet syndrome.
- Clinical benefits are temporary, suggesting a need for repeat procedures.
- Repeat injections are recommended every 3 months for sustained pain relief.
