Introduction:
We sought to document the efficacy of interlaminar epidural steroid injections (ESIs) for the relief of low back pain in a rural population.
Methods:
We conducted a prospective observational cohort study with brief follow-up telephone interviews at 1, 3 and 6 months after interlaminar ESI.
Results:
A total of 47 ESIs were administered to the 24 participants. In an intention-to-treat analysis, pain relief was achieved in 78.7%, 55.3% and 27.7% of participants at 1, 3 and 6 months.
Conclusion:
Interlaminar ESIs, without fluoroscopic guidance, were effective for up to 3 months of symptom relief.
