Surgery is usually the last resort in the treatment of chronic back pain, used when all other options have been exhausted. One of the non-surgical options providing pain relief is epidural steroid injections.
But how effective are these injections? In a report, the American Academy of Neurology in association with a number of medical schools has thrown up some interesting facts. The salient points of these findings are:
* Epidural steroid injections show some improvement in chronic low back pain conditions, marked by pain radiating down the hips and legs, between 2 and 6 weeks of injection.
* However, these injections do not -
# provide long term pain relief beyond 3 months,
# improve the functioning of lower back, or
# obviate the need for surgery.
Therefore regular use of these injections cannot be recommended.
* There is a shortage of well-designed placebo-controlled studies (as opposed to uncontrolled clinical observations or case studies) to conclusively comment on the efficacy of epidural steroid injections in radicular low back pain.
Finally, though rare, a number of side effects ranging from headaches to increased pain and even meningitis and spinal hematoma have been reported in the aftermath of these injections.
