Epidural application of cortico-steroids in low-back pain and sciatica.
Seven women and nine men, aged 27-59 years (mean 45), with lumbar pain and sciatica had epidural blocks once with 80 mg of depo-medrol and lidocaine in individual doses. All had static and kinetic lumbar pain up to 16 years and all but four also pain radiating to the lower limbs. Radiculography was "negative" in all patients, but three exhibited minor neurological abnormalities. ⋯ In the remainder complaints were unaffected by the epidural injection. These discouraging results are not compatible with other reports, and a planned double-blind randomized investigation was abandoned. For the present category of patients (long-lasting complaints, previous "disc" operations) we found the epidural steroid injection useless.

Recognizing that not all patients with low back pain have lumbar disc disease, the authors began to inject facet joints in June 1982 and have experience now with 21 patients, each injected under fluoroscopic control with a mixture of local anesthetic and steroid. One technical problem occurred when large osteophytes blocked access to the facet joints. Otherwise, there were no complications and minimal morbidity. ⋯ Facet joint disease may be a significant cause of low back pain. The above three criteria are useful in clinical identification of patients with this problem. Facet joint injections play an important role in the diagnosis and treatment of low back pain.
