AbstractEpidural steroid injections are widely used as part of the conservative care for symptomatic herniated lumbar discs. There are studies showing their effectiveness, and some studies demonstrating no clinical benefits. The purpose of this study was to evaluate the effectiveness of epidural steroid injections for patients with symptomatic lumbar disc herniations who were surgical candidates. Sixty-nine patients were diagnosed with a herniated disc in the lumbar spine and remained symptomatic despite conservative care, and were treated with an epidural injection in an attempt to avoid surgical discectomy. Of the total group of 69 patients (average age = 44.8 years, range 19-77 years, average follow-up = 1.5 years), 53 (77%) had successful resolution or significant decrease of their symptoms and were able to avoid surgery. Only 16 (23%) patients failed to have significant relief of their symptoms and required surgical treatment of their herniated disc. Epidural steroid injections have a reasonable success rate for the alleviation of radicular symptoms from lumbar herniated discs for up to twelve to twenty-seven months. Patients treated with injections may be able to avoid surgical treatment up to this period and perhaps even longer.
