Steroid vs saline injections for chronic radiculopathy

This group of Norwegian, Danish, and Dutch researchers tested caudal epidural steroid or saline injections in chronic lumbar radiculopathy. They performed a multicentre, blinded, randomized controlled trial. Enrollees were randomized to two subcutaneous sham injections of 2 mL 0.9% saline, two caudal epidural injections of 30 mL 0.9% saline, or two caudal epidural injections of 40 mg triamcinolone acetonide in 0.9% saline. The patients’ pain and disability were measured with Oswestry disability index scores.

The researchers found: "All groups improved after the interventions, but we found no statistical or clinical differences between the groups over time. For the sham group (n=40), estimated change in the Oswestry disability index from the adjusted baseline value was -4.7 at 6 weeks, -11.4 at 12 weeks, and -14.3 at 52 weeks. For the epidural saline intervention group (n=39) compared with the sham group, differences in primary outcome were -0.5 at 6 weeks, 1.4 at 12 weeks, and -1.9 at 52 weeks. For the epidural steroid group (n=37), corresponding differences were -2.9, 4.0, and 1.9. Analysis adjusted for duration of leg pain, back pain, and sick leave did not change this trend."

The researchers concluded: "Caudal epidural steroid or saline injections are not recommended for chronic lumbar radiculopathy."

Neither steroid nor saline injections were significantly different from sham injections in chronic radiculopathy.
