Efficacy of Pulse Radiofrequency Treatment in Patients With Coxarthrosis

In the procedures to be performed under fluoroscopy, vascular structures will be detected primarily by ultrasonography for safety purposes. A standard RF device will be used for the process. A 22-gauge and 10 cm straight radiofrequency cannula with 1 cm active tip will be used. For each nerve, sensory stimulation will be performed at 50 Hz and the patient will be expected to feel numbness and tingling with a maximum 0.7 V. Motor stimulation will be at 2 Hz and no muscle contraction up to 2 V is expected. Following the appropriate cannula placement, pulse radiofrequency will be applied to each nerve in 2 cycles of 120 seconds for the patients in this group. The pulse radiofrequency current will be 20 milliseconds wide and 45 volts in size. The tip temperature shall not be more than 42℃.

Following the appropriate cannula placement, patients will be injected with 1 cc betamethasone and 1 cc 1% lidocaine for each nerve. A total of 2 cc volume will be injected for each nerve.
