Two Different Approaches During Fluoroscopically Guided Interlaminar Lumbar Epidural Steroid Injection

Overview

The purpose of this study is to compare two different approaches (midline and parasagittal) during interlaminar lumbar epidural steroid injection (LESI), and to verify the role of concordant pressure paresthesia occurring during the LESI in determining outcome. The investigators are planning to include 100 patients, undergoing LESI for radicular low back pain. This will be single-blinded randomized study. Every patient will receive the same medication we would use regardless of participating in the study. The patients will be randomly assigned to one of two groups, based on the approach: * Group I (50 patients) - will get LESI using midline (MIL) approach. * Group II (50 patients) - will get LESI using parasagittal interlaminar (PIL) approach.
