In patients with symptoms caused by intervertebral disk displacement, studies of epidural corticosteroid injections have produced compelling evidence of a short-term analgesic effect (lasting about 3 weeks), despite a number of discrepancies. In contrast, no reductions were noted in the time off work or need for surgery. Strong evidence supports a short-term symptomatic effect of guided transforaminal corticosteroid injections, and there is also some evidence of a long-term effect. ⋯ Intradural injections should not be performed, as they may induce adverse effects and have not been proved effective. Interspinous injections and iliolumbar ligament injections can be considered in selected patients. Although published data have led to controversy about the effectiveness of local corticosteroid injections, a short-term analgesic effect is usually obtained, making this modality useful for the second-line treatment of patients with disk-related sciatica, as well as in selected patients with chronic low back pain.
