Brief Summary

Lumbar radicular pain affects the person's quality of life. The most common cause of lumbar radicular pain is disc herniation. In radicular pain due to lumbar disc herniation, epidural steroid injections are frequently applied to patients who do not benefit from medical treatment and physical medicine modalities. Epidural steroid injection inhibits the synthesis and release of pro-inflammatory substances that develop as a result of mechanical compression.In the transforaminal epidural technique, the solution is administered to the anterior epidural space and spreads to the ipsilateral periradicular area. The applied solution does not cross the midline and there is no contralateral drug spread. Although bilateral transforaminal epidural steroid injection is recommended in unilateral lumbosacral disc herniation because the inflammation is bilateral, unilateral transforaminal steroid injection has been applied in most studies. We aimed to to evaluate the effects of unilateral and bilateral transforaminal epidural steroid injection on pain intensity, functionality and medication use in unilateral lumbosacral disc herniation

Outcome Measures

Primary Outcomes (1)

  • pain severity

    In patients who received unilateral and bilateral transforaminal steroid injection, pain severity change by using Numeric Ratin Scala was observed 3 months after the procedure.

    3 months

Secondary Outcomes (3)

  • functionality

    3 months

  • medication use

    3 months

  • Complication

    3 months

Study Arms (2)

Unilateral transforaminal epidural block

OTHER

The necessary oblique and cranio-caudal angles will be provided in fluoroscopy for the patients' designated procedure area. Skin and subcutaneous tissue anesthesia will be applied to the injection site with 3 ml of 2% prilocaine. The neural foramen will be entered using a blunt-tipped sympathetic block needle and a guiding needle. After needle localization is confirmed with antero-posterior and lateral fluoroscopic images, 1-2 ml of contrast material will be injected following negative aspiration. After confirming the contrast material spread in the anterior epidural area and periradicular area, 8 mg dexamethasone will be injected. If the application will be performed bilaterally, the specified techniques will be applied in half the same way on the bilateral side. Patients will be observed for one hour after the procedure for possible complications.
