Machine used is,(NeuroTherm 1100) RF lesion generator. The standard radiofrequency technique used, patient in sitting position , non-invasive blood pressure and peripheral oxygen saturation will monitored with non invasive pulse oxymetry. Vascular peripheral intravenous routes will opened shoulder region exposed and under complete aseptic technique skin will be anesthetized with 2.0 ml of 2% lidocaine at puncture site, suprascapular notch was identified. The landmark to guide the initial entry point was a line drawn along the length of the scapular spine, bisected with a vertical line from the angle of the scapula. A radiofrequency needle was introduced through the skin, 2.5 cm along the line of the spine in the upper outer quadrant, and then guided to the edge of the suprascapular notch by use of C_arm guide fluoroscopy with the image intensifier (22-gauge, 50-mm needle; 5-mm active tip) The nerve was located accurately by stimulating at 2 Hz (threshold < 0.5 V). PRF was applied for 120 seconds 2 or 3 times (NeuroTherm radiofrequency lesion generator) creating a tingling and paresthesia felt in the dermatomal distribution of the nerve in question. Motor stimulation (2 HZ). Impedances were checked to ensure a complete electrical circuit and range from 200 to 400 Ohms, if impedance is > 400 1 ml of 1% lidocaine will be injected.
