"Comparison of the Effectiveness of Conventional Radiofrequency Thermocoagulation and Chemical Ablation With Phenol on Articular Branches of Femoral and Obturator Nerves in Chronic Hip Pain"

"Our study is designed as a double-blind, prospective randomized controlled trial. Blinding will be ensured by keeping the researcher performing pain diary follow-ups unaware of which procedure was applied to each patient.

Patients will be randomized using computer-assisted methods. Following approval from the hospital ethics committee, clinical trial registration will be conducted. From 2024 to 2025, patients presenting with chronic hip pain to the Department of Algology at ADU Faculty of Medicine will be divided into two groups. In Group 1, chemical ablation of the femoral and obturator nerve branches with phenol under ultrasound guidance will be performed. In Group 2, conventional radiofrequency thermocoagulation of the articular branches of the femoral and obturator nerves under ultrasound guidance will be applied.

During the study, pain intensity will be assessed using the Numerical Rating Scale (NRS) at baseline, 2 hours post-procedure, and at 1 month and 3 months post-procedure for both Group 1 and Group 2. The WOMAC scale will be used to evaluate their functional capacity."
