Are epidural corticosteroid injections safe and more effective than other injections for the treatment of lumbosacral radicular pain?
Epidural corticosteroid injections for the treatment of lumbosacral radicular pain may offer modest short-term (two weeks to three months) benefit compared with placebo injection for radicular leg pain (mean difference [MD] = −4.93; 95% CI, −8.77 to −1.09 on a scale of 0 to 100) and disability (MD = −4.18; 95% CI, −6.04 to −2.17 on a scale of 0 to 100). After three months, there does not appear to be any added benefit with the use of corticosteroid.1 (Strength of Recommendation: B, based on inconsistent or limited-quality patient-oriented evidence.) Minor adverse effects from corticosteroid injection are no more common than with placebo injection, based on very low-quality data.
Lumbosacral radicular pain is radiating pain that results from injury or irritation of nerve roots in the lower back. Lumbosacral radicular pain is most often caused by disc herniation with nerve root compression. Most patients with this condition improve over time, but the degree of pain and disability is variable and leads some patients to seek invasive intervention. Epidural corticosteroid injections can be administered in an outpatient setting. This review sought to determine if epidural corticosteroid injection is more effective than placebo injection for the treatment of lumbosacral pain and disability.
This Cochrane review included 25 randomized trials and 2,470 patients1; it updates a previous 2012 review. Six additional studies were added to this review, but the overall conclusions were largely unchanged from 2012. The review considered only trials that included a placebo injection as the control arm of the study. Results of individual studies were grouped by timing of response measured and thus characterized as immediate (less than two weeks), short term (two weeks to three months), in
