Living with lumbar radiculopathy means dealing with sharp, radiating pain that can make daily movement difficult. Doctors often use steroid injections to calm the nerves and reduce inflammation. However, not all injection techniques are the same, and choosing the right one matters for your recovery.
A review of 31 studies involving over 2,400 patients compared different methods. The results showed that transforaminal epidural steroid injections (TFESI) provided better pain relief and improved physical ability at several milestones compared to interlaminar injections. While TFESI also showed some advantages over caudal injections in the short term, those results were less consistent over a full year.
Combining two types of injections—TFESI and CESI—showed the most consistent improvements for both pain and disability across all follow-up times. Because the evidence for this combined approach is still limited, more large-scale trials are needed to confirm its long-term benefits. Talk to your doctor about which specific injection technique best fits your personal needs.
Common questions
Which injection method is most effective for my back pain?
The study found that transforaminal epidural steroid injections (TFESI) provided significantly better pain reduction and improved disability scores at 2 weeks, 1 month, 3 months, and 6 months compared to interlaminar injections. While it also showed some benefits over caudal injections, those results were less consistent over a full year.
Are there any benefits to combining different injection types?
Combining transforaminal (TFESI) and caudal (CESI) injections resulted in significantly greater improvements in both pain relief and disability across all follow-up timepoints. However, researchers note that evidence for this combined approach is still limited and needs more study.
How long do the benefits of these injections last?
The research tracked patients at 2 weeks, 1 month, 3 months, 6 months, and 12 months. While some methods showed better results in the first few months, the data for long-term outcomes—specifically beyond one year—is still being gathered to confirm which method works best over time.
