Epidural steroid injections for lumbar spinal stenosis.
Degenerative lumbar stenosis is a common source of pain and disability in the elderly. It presents clinically with a variety of symptoms, though neurogenic claudication is the hallmark. There is a multifactorial pathogenesis to lumbar stenosis and its symptoms, and thus, there are multiple management approaches available. Epidural steroid injections (ESIs) are a popular choice in management, however, the literature is vague in definitive support of their use, and providers that utilize injections can use variable techniques to access the spinal canal in order to deposit the steroid at the appropriate site. This article will review degenerative lumbar stenosis in general and focus on the use of ESIs to better define their role in this management process. In addition, the evidence to discern the optimal injection route will be presented.
