A Randomized Clinical Trial of Three Different Steroid Agents for Treatment of Low Backache through the Caudal Route

Background Although epidural steroids are commonly used for conservative management of sciatica, controversies exist regarding optimal approach, type and dose of steroids, volume of injectate and frequency of administration. This randomized comparative blinded study was undertaken to compare the efficacy of caudal methylprednisolone acetate with triamcinolone acetonide and dexamethasone acetate, for pain relief for sciatica associated with lumbar-disk herniations.
