Brief summary: the aim of the study is to identify predictive factors for the success of transforaminal epidural injection in the treatment of patients with lumbosacral radiculopathy

Detailed description: Lumbar radicular pain (known as sciatica) represents a prevalent medical and socioeconomic problem.

More than half of the patients with sciatica report a decline in their activities of daily living and ability to work.

Mixed Pathologies as foraminal stenosis, spondylolisthesis, and space-occupying lesions in the lumbar spine can cause Sciatica but the most common cause is lumbar disc herniation. (1) Overall, the vast majority of patients with lumbosacral radiculopathy recover with conservative care as trial of bed rest, oral medications, lumbar corsets and physiotherapy. (2) The involvement of inflammation has attracted the use of steroids (corticosteroids) to reduce the inflammation and, thereby, relieve the pain. Injections of steroids, by various routes, have been used as an alternative to surgery, and as an alternative or complement to conservative therapy, for the treatment of lumbar radicular pain. (3) Steroids are believed to have a therapeutic effect due to their anti inflammatory properties.

This belief is supported by evidence from in vitro studies that show that steroids have a role in decreasing inflammatory mediators such as cytokines and chemokines another study suggests that steroids may provide a stabilizing effect on nociceptive signaling in C-fibers and suppression of ectopic neural discharges. (4) The most widely used injection therapy is epidural injection of steroids, by either the interlaminar route or the caudal route. More contentious are transforaminal injections of steroids. These involve the injection of steroids directly and accurately onto the affected spinal nerve, under radiologic guidance. Meanwhile, transforaminal injection of steroids has been shown to be more effective than interlaminar injection of steroids (5) Transforaminal epidural injection may be by autologous Platelet Rich Plasma (PRP) as a novel pharmaceutical agent that has strongly emerged in recent years to treat patients of lumbar disc herniation.(6)
