Lumbosacral epidural steroid injections

Epidural steroid injections for the treatment of low back pain and associated leg pain have been used for half a century. Initial use was empirical and not without controversy. An abundant literature has accumulated describing their use and potential benefit. Previous controlled studies are limited by methodology and technique. A growing body of literature suggests that they exert some of their clinical effect by reducing epidural and perineural inflammation. More current studies using fluoroscopy with radiographic contrast and precise epidural steroid placement suggests they may obviate surgery in some patients with true radicular pain.
