INTRODUCTIONLow back pain (LBP) is a most common problem. Approximately 80% Indian experience LBP during their lifetime. An estimated 15-20% develops protracted pain, and 2-8% has chronic pain. Every year, 3-4% of the population is temporarily disabled, and 1% of the working-age population is disabled totally and permanently because of LBP.1 LBP is second only to the common cold as a cause of lost work time; it is the fifth most frequent cause for hospitalization and the third most common reason to undergo a surgical procedure. LBP is defined as chronic after 3 months because most normal connective tissues heal within 6-12 weeks unless pathoanatomic instability persists. A slowed rate of tissue repair in the relatively avascular intervertebral disc may impair the resolution of chronic LBP. Traumatic or degenerative conditions of the spine are the most common causes of chronic LBP. A number of anatomic structures of the lumbar spine have been considered as the origin of LBP. [2][3][4][5][6] Many studies have shown significant improvement with epidural injections with or without steroids in patients with chronic LBP. Among the multiple interventions used in managing chronic spinal pain; lumbar epidural injections have been used extensively to treat lumbar radicular pain. Epidural steroid injections (ESIs) are a common treatment option for many forms of LBP and leg pain. They have been used for low back problems since ABSTRACT Background: Intervertebral disc herniation, spinal stenosis, intervertebral disc degeneration without disc herniation, and post lumbar surgery syndrome are the most common diagnoses of chronic persistent low back and lower extremity symptoms, resulting in significant economic, societal, and health care impact. Epidural injections are one of the most commonly performed interventions in managing chronic low back pain (LBP) along with surgical intervention. Cost effectiveness and affordability has become the cornerstone of evidence-based medicine, and has an influence on coverage decisions, especially in developing countries such as India. LBP is a common problem. The aim of this study was to find the therapeutic efficacy of epidural steroid injections (ESIs) in chronic LBP. Methods: 50 patients presenting with LBP with or without radiculopathy treated with ESIs were prospectively followed for average duration of 12 months. Results: Fifty patients were included in this study with average age 51.02±7.1, out of these 26 (52%) were males and 24 (48%) females. Significant pain relief (>50%) was demonstrated in 43 (71%) of patients and functional status improvement was demonstrated by a reduction of 40% in Oswestry disability index (ODI) score in 49 (81%) patients. Conclusions: ESIs are very effective and significantly reduce pain in patients with chronic function-limiting LBP.
