Objective:
Facet joint injections (FJIs) and medial branch blocks (MBBs) are commonly used interventions for chronic spinal pain, but their comparative effectiveness remains unclear. This meta-analysis aimed to compare the pain relief, functional improvement, complications, and patient satisfaction associated with FJI and MBB.
Methods:
A systematic review and meta-analysis of randomized controlled trials and observational studies were conducted. Primary outcomes included pain relief (numerical rating scale) and functional improvement (Oswestry Disability Index [ODI]/Neck Disability Index). Secondary outcomes assessed adverse effects and patient satisfaction. The differences in characteristics between patients who were readmitted and those who were not were identified and analyzed using the Review Manager software.
Results:
FJI resulted in lower pain and ODI scores compared to MBB, but the differences were not statistically significant. However, patient satisfaction was significantly higher in the FJI group (odds ratio, 1.81; 95% confidence interval, 1.02-3.24; p=0.04). Additionally, FJI had fewer adverse effects than MBB.
Conclusion:
Both FJI and MBB are effective for chronic spinal pain, but FJI may be preferred for patients seeking immediate pain relief with fewer complications. Further high-quality studies are needed to refine treatment guidelines.
