Scientific title | Epidural Sacral Injection study: effect of volume and triamcinolone on chronic lumbosacral radiculopathy? |
Study acronym | ESI |
Study objectives | ESI (Epidural Sacral Injection) is a method of treating low back pain and radiculopathy that is the subject of considerable discussion. Although the method has been in existence for nearly 100 years, there are only a few good randomised controlled studies. In Nelemans et al (2000), evidence for the method is given as weak, and studies of a high scientific quality are sought. To investigate these factors in greater detail, randomised controlled studies are needed to clarify the effect of volume and steroids versus placebo. Many patients with chronic low back pain and sciatica feel that they have few good therapeutic options besides surgery. Only a few patients with sciatica are suitable for surgical treatment. The surgeon needs a correspondence between the clinical level of radiculopathy and Magnetic Resonance (MR) diagnosis of disc protrusion. Many patients lack this correspondence. We therefore want to conduct the study on patients with clinical signs of lumbosacral radiculopathy, where the pain has lasted for more than 12 weeks (chronic) and where surgical treatment is not indicated at the time of inclusion due either to lack of correspondence between clinical and MR finding or low Oswestry Disability Index (ODI). In our study, we wish to use a corticosteroid preparation with a weak anti-inflammatory effect. Triamcinolone acetonide in a strength of 40 mg/ml and a quantity of 1 ml meets this requirement. The effect is to be compared with placebo (2 ml NaCl 0.9% subcutaneously) and volume (30 ml NaCL 0.9% epidural). In many studies, injections have been used with a small volume (less than 10 ml). We will use a volume of 30 ml to be sure that the medicinal product is distributed throughout the epidural space in the lumbosacral column up to level L2. If our study can demonstrate a significant therapeutic effect for ESI of steroid, the method could become an important tool in the treatment of patients with low back pain and radiculopathy. We could also clarify in the study whether there are special subgroups of patients with radiculopathy (Signal changes in the disc, Covered prolapse, Free prolapse, Thickened nerve root, Disclosed nerve root) that respond better to steroid injection. If the method can also be proven to be easy to perform, and associated with few serious complications and adverse drug reactions, it could become useful in both the treatment and rehabilitation of sciatica patients. At present, we do not know enough about the risk associated with use of the method, the incidence of side-effects and what should be regarded as adequate follow-up of patients. Hopefully, a study could yield valuable information on this. Given a good effect from the treatment and a low incidence of side-effects, we will probably be able to substantiate a positive gain in the form of reduced suffering for the individual in addition to a socioeconomic gain from patients recovering their health and being able to return to work more quickly. |
