【 摘 要 】

OBJECTIVE: To compare the interlaminar and transforaminal block techniques with regard to the state of pain and presence or absence of complications.METHOD: This was a randomized double-blind prospective study of descriptive and comparative nature, on 40 patients of both sexes who presented lumbar sciatic pain due to central-lateral or foraminal disk hernias. The patients had failed to respond to 20 physiotherapy sessions, but did not present instability, as diagnosed in dynamic radiographic examinations. The type of block to be used was determined by means of a draw: transforaminal (group 1; 20 patients) or interlaminar (group 2; 20 patients).RESULTS: Forty patients were evaluated (17 males), with a mean age of 49 years. There was a significant improvement in the state of pain in all patients who underwent radicular block using both techniques, although the transforaminal technique presented better results than the interlaminar technique.CONCLUSION: Both techniques were effective for pain relief and presented low complication rates, but the transforaminal technique was more effective than the interlaminar technique.
