Epidural steroid injection is an established treatment modality for intervertebral disc prolapse. It is a low-risk alternative to surgical intervention in some patients for whom noninvasive treatment has failed. Caudal epidural steroid injection is one of the most widely used methods for pain relief. The aim of this study was to determine the significance of same dose in different volume of caudal epidural steroid injection in the treatment of lumbar degenerative disc disease. Prospective study was conducted during 2007 to 2009. 100 Patients were randomized in to two groups, of which 50 % (group A) received 4 ml of steroid with isotonic saline and remaining 50 % (group B) received 12 ml. Injection was given in prone position through a 22-G needle in to the epidural space through the sacral hiatus. The average follow-up was 18 months. Outcomes scores included the SF-36, Oswestry disability index and pain VAS and were recorded in the pre and post injection periods.Introduction
