[Pain relief in lumbosacral radicular syndrome: the role of transforaminal epidural injections with glucocorticoids].

Lumbosacral radicular syndrome is characterized by radiating pain into a part of the leg typically served by one nerve root in the lumbar or sacral spine. The most common cause of radicular syndrome is a herniated disk. The estimated annual incidence of radicular syndrome in The Netherlands is 9 cases per 1000 adults per year. The course of radicular syndrome is favorable, with resolution of leg pain within 3 months from onset in the majority of patients. During the first few weeks post-onset treatment focusses on pain relief. Besides pain medication, transforaminal, fluoroscopic injections with corticosteroids can be chosen. Transforaminal, fluoroscopic injections with glucocorticoids are safe and effective compared to placebo. The position within the treatment protocol for radicular pain of epidural steroid injections has yet to be determined based upon further scientific knowledge.
