AbstractA prospective, randomised, double-blind study was carried out to compare the respective efficacies of transforaminal and interspinous epidural corticosteroid injections in discal radiculalgia. Thirty-one patients (18 females, 13 males) with discal radicular pain of less than 3 months' duration were consecutively randomised to receive either radio-guided transforaminal or blindly performed interspinous epidural corticosteroid injections. Post-treatment outcome was evaluated clinically at 6 and 30 days, and then at 6 months, but only by mailed questionnaire. At day 6, the between-group difference was significantly in favour of the transforaminal group with respect to Schober's index, finger-to-floor distance, daily activities, and work and leisure activities on the Dallas pain scale. At day 30, pain relief was significantly better in the transforaminal group. At month 6, answers to the mailed questionnaire still showed significantly better results for transforaminal injection concerning pain, daily activities, work and leisure activities and anxiety and depression, with a decline in the Roland-Morris score. In recent discal radiculalgia, the efficacy of radio-guided transforaminal epidural corticosteroid injections was higher than that obtained with blindly-performed interspinous injections.
