Comparison of Femoral and Obturatory Nerve Joint Branches Conventional Radiofrequency Thermocoagulation ,Intraarticular Steroid Injection and Pericapsular Nerve Group (PENG) Block in Chronic Hip Pain

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.

The patients were placed in the supine position in the operating room. The patient was stained sterile with povidone iodide. The femoral neck was detected under ultrasonography and the joint capsule was entered with a 22G 9 cm spinal needle. Then, 5 cc bupivacaine and 5 mg betamethasone were given and the procedure was terminated.

The patients were placed in the supine position in the operating room. The patient was stained sterile with povidone iodide. The high-frequency linear ultrasonography probe was placed on the anterior superior iliacspina (ASIS). Later, the anterior inferior iliac spine (AIIS) was detected by descending caudally. Afterwards, the probe was brought to the oblique position and AIIS, iliopubikeminence, psoas muscle and tendon were seen. Using a 22G 90-mm Quinckespinal needle, the tendon of the iliopsoas muscle was entered in the lateral-medial direction in the in-plane plane and bone contact was achieved. After negative aspiration, 15 ml of 0.5% bupivacaine were administered by seeing the appropriate drug distribution.
