The Effect of Adding a Local Anesthetic to Transforaminal Epidural Injection in Cervical Disc Herniation.

The study is designed as a double-blind, prospective, randomized controlled trial. Blindness is ensured by having different researchers performing the interventional procedures and monitoring the pain diaries, thus preventing them from knowing which procedure is performed on which patient. Patient randomization will be performed using computer assistance. After obtaining approval from the hospital ethics committee, clinical trials will be initiated. Patients who present to the Department of Neurology, Algology Division, ADÜTF between 2025-2026 and undergo DRG-PRF and TFAESI for radicular pain due to cervical disc herniation will be divided into two groups. Patients in Group 1 will undergo DRG-PRF and TFAESI with the addition of local anesthetic. Patients in Group 2 will undergo DRG-PRF and TFAESI without the addition of local anesthetic. During the study, NRS score measurements will be taken to assess pain intensity in patients in both Group 1 and Group 2 before the procedure and at 1, 3, and 6 months post-procedure follow-ups. Neurological and musculoskeletal examinations will be performed during routine check-ups before the procedure and at 1, 3, and 6 months after the procedure, and any developing side effects will be recorded.
