Sixty eight cases of low backache not responding to the treatment of bed rest, traction and analgesics were subjected to epidural injection and were studied in 4 different groups. Patients in Group C (40) receiving hydrocortisone acetate (5 ml), 2 per cent xylocaine (10-20 ml) alongwith contrast medium (30-40 ml) showed good results with relief of pain for more than 6 weeks in 80 per cent cases. The group which received hydrocortisone acetate and xylocaine (8 patients) without the contrast medium showed 50 per cent good results. The other 2 groups receiving only contrast medium for diagnostic purposes (10) and contrast medium with local anaesthetic agent (10) showed only temporary effect by relieving pain for less than one week in majority of the cases.
