Transforaminal and Parasagittal Approach in Lumbar Epidural Steroid Injection

Study Overview
=================
Brief Summary
-----------------
Lumbar epidural injection is used in the treatment of lumbar radicular pain. There are three different application methods: lateral parasagittal, midline interlaminar and transforaminal epidural injection. Investigator aimed to compare lateral parasagittal and transforaminal epidural injection methods. The purpose of the study is to determine which method is more efficient.

Detailed Description
-----------------
It was planned to recruit 60 participants in the study. Interlaminar epidural steroid injection will be applied to 30 patients with midline and 30 patients with lateral parasagittal approach. All patients will receive Oswestry disability index before and 2-4-12 weeks after the procedure. All patients will receive Somatization Amplification Scale (SSAS) before the treatment. The results of the patients will be compared. It will be investigated which method is more effective.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Oswestry disability index | Oswestry Low Back Pain Disability Questionnaire, the Oswestry Disability Index helps to measure a patient's lower back pain. It evaluates the extent to which the patient's level of function is restricted by the pain, concentrating on the effects rather than the nature of the pain. 0% to 20%: minimal disability 41%-60%: severe disability 61%-80%: crippled | baseline, week 4, week 12 |
