Background and Aims The primary aim of our study is to investigate the effects of ultrasonography and fluoroscopy-guided radiofrequency thermocoagulation on the articular branches of the femoral and obturator nerves in chronic hip pain, and the secondary aim of the effects on hip function and quality of life.
Methods Forty-eight patients with hip pain for more than 3 months were included in the study. VPS scale and WOMAC, SF-12 questionnaires were applied to the patients at the 1st, 3rd and 6th months before and after the procedure. BMI, comorbidity, diagnosis, analgesics used and complications were recorded.
Results Hip pain was associated with osteoarthritis in 77.1%, postoperative hip pain in 12.5%, malignancy in 8.3%, and avascular necrosis in 2.1%. The VPS score was 9.0 (6.0-10.0) at baseline, 2.0 (.0-8.0) in the first week after the procedure, 4.0 (.0-9.0) in the first month, 5 in the third month, 5.0(.0-10.0) at the sixth month, and a significant decrease was observed in the VPS score (p <0.001). WOMAC index decreased statistically significantly in the post-procedure period (p<0.001). The SF12-PCS score increased significantly in the postoperative period (p<0.001). The SF 12-MCS score did not change significantly after the procedure (p0115). It was observed that drug use increased statistically significantly after the first month (p=0.042). As a complication, a patient has a self-healing motor deficit.
Conclusions We think that radiofrequency thermocoagulation to the articular branches of the femoral and obturatory nerve in chronic hip pain provides pain relief, improvement in hip functions and improvement in qualityoflife for up to 6 months.
