The diagnostic block was effective, brachial plexus PRF was applied (Figure 2A). After disinfection, Sparq ultrasound system (Royal Philips, Amsterdam, the Netherlands) was used with a linear transducer (5-12 MHz) in-plane interscalene approach to obtain a transverse axial view of brachial plexus (Figure 2B). When the needle was close to the nerve and patient's reproduced pain was at 0.4 mA, it was the ideal position for PRF (Figure 2C). The patient received PRF lesions at 42 C in 240 seconds for 3 times with radiofrequency generator (Cosman Medical, Inc.,) (Figure 2D).
