Treatment of Chronic Hip Pain by Application of Conventional Radiofrequency Thermocoagulation to the Articular Branches of the Femoral and Obturatory Nerve

Radiofrequency Thermocoagulation to the Articular Branches of the Femoral and Obturatory Nerve in Chronic Hip Pain

The estimated prevalence of hip joint pain is 7% in men and 10% in women over the age of 45 years.Although physical therapy and weight loss, use of walking aids (such as walking sticks) and analgesic agents are used as conservative treatment methods, these methods usually provide short-term and partial benefits.The anterior sensory innervation of the hip joint is provided by the articular branches of the femoral and obturatory nerve. Denervation of the articular branches of the femoral and obturator nerves with the radiofrequency thermocoagulation (RFT) method is a method used in chronic hip pain. In this study, we aimed to show the decrease in pain levels and the effect on quality of life of patients who underwent hip RFT.

Study Overview

• Status: Recruiting
• Conditions: Hip Pain Chronic
• Intervention / Treatment: Procedure: Radiofrequency thermal coagulation of articular branches of femoral and obturator nerves

Detailed Description

Hip pain is a common medical condition with increasing age.The effectiveness of conservative methods used in hip pain is limited.Since the lifespan of prostheses used in hip surgery is limited, new methods are needed in the treatment of pain.The anterior sensory innervation of the hip joint is provided by the articular branches of the femoral and obturatory nerve. Denervation of the articular branches of the femoral and obturator nerves with the radiofrequency thermocoagulation (RFT) method is a method used in chronic hip pain.In previous studies with small groups, it was shown that radiofrequency thermocoagulation procedure caused 50% reduction in hip pain between 1-11 months.Hip joint radiofrequency thermocoagulation is a procedure applied in our clinic. In this study, we aimed to show the decrease in pain levels and the effect on quality of life of patients who underwent hip RFT.

Intervention / Treatment

Other: Preoperative and Postoperative Pain Level; The preoperative pain level, hip function and quality of life of patients who underwent radiofrequency thermocoagulation to the articular branches of the femoral and obturatory nerve in chronic hip pain will be compared with the postoperative pain level, hip function and quality of life of these patients.

Procedure: Radiofrequency thermal coagulation of articular branches of femoral and obturator nerves; Patients are operated under sedation in the operating room. C-arm fluoroscopy device is used for imaging purposes for radiofrequency thermocoagulation process. In order to prevent vascular injury, the needle is advanced under the guidance of ultrasonography. There are target points determined in fluoroscopy for the femoral nerve and the obturatory nerve. Before the thermocoagulation procedure, local anesthetic and steroid are injected into each of the target points. Patients who do not have any complications after the procedure and who are mobilized are discharged in the 2nd hour.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Chronic pain level	For this, the patients' preoperative, 1st month, 3rd month and 6th month VPS (Verbal Pain Score) scores will be checked. A 50% reduction in the verbal pain score will be considered significant.	1 month,3 month, 6 month

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Hip functional capacity	For this purpose, the WOMAC (Western Ontario and McMaster Universities Arthritis Index) scale will be checked at the 1st, 3rd, 6th, 6th months in order to evaluate the functional capacity before the procedure.	1month,3 month,6month

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Life Quality	For this purpose, patients will be subjected to the Short Form-12- test, which is a short scale of quality of life at 1st month, 3rd month and 6th month.	1month, 3 month,6 month
Acute pain	Week 1 Verbal Pain Score will be checked to observe the improvement in acute pain in patients. A 50% decrease in verbal pain score will be considered significant.	1 week
