Comparison of Epidural Steroid Injections with conservative management in patients with lumbar radiculopathy.

OBJECTIVE:

To determine the difference in short- and long-term pain improvement between lumbar Epidural Steroid Injections (ESIs) and conservative management in patients with lumbar radiculopathy.

STUDY DESIGN:

Quasi-experimental study.

PLACE AND DURATION OF STUDY:

The Postgraduate Medical Institute of Hayatabad Medical Complex, Peshawar, from April 2005 to March 2007.

METHODOLOGY:

Fifty elective patients fulfilling the inclusion criteria were randomly divided into two groups. Patients in the steroid group were treated with 80 mg of methylprednisolone injected in combination with 3 ml of 2% plain xylocaine and 3 ml of normal saline in the lumbar epidural space, while patients in the conservative group were treated with bed rest, non-steroidal anti-inflammatory agents, muscle relaxants, and opioids. All the 50 patients in the two groups were regularly assessed at 2 weeks, 1 month, 3 months and 6 months of periods for pain score by the Visual Analogue Scale (VAS), patients satisfaction score and any unwanted side effects.

RESULTS:

A marked improvement of the pain score and patients satisfaction score were noticed in the steroid group. Less significant improvement was seen in the conservative group during the initial period i.e 2 weeks and 1 month (p < 0.05). The difference in Visual Analogue Scale (VAS) and patients satisfaction score was non-significant in chronic stages of treatment in both groups (p > 0.05).

CONCLUSION:

Epidural steroid injections in acute symptoms of sciatica are considered to be a better option compared to conservative treatment.
