After being informed about the study and potential risks, all patients giving written informed consent will undergo screening to determine eligibility. Patients who meet the eligibility criteria will be randomized in a double-blind manner to two groups. Patients assigned to Group A will undergo a fluoroscopy guided procedure while patients in Group B will undergo a microendoscopic combined with ultrasound technique.
The purpose of this study is to compare the Microendoscopic combined with ultrasound technique to the standard routinely used X-ray guided transforaminal steroid injection technique.
