Bupivacaine or Radiofrequency for Shoulder Pain

Suprascapular nerve block with Bipuvacaine: a 50mm 22G needle (Stimuplex, BBraun) was introduced up to the suprascapular fossa, guided by ultrasound, and the location was confirmed by motor stimulation with contraction of the supraspinatus and infraspinatus muscles. Next, 5 ml of 0.25% bupivacaine with adrenaline was injected.

After confirming the location, the needle mandrel was removed and the radiofrequency cannula was introduced through the needle, 2ml of 1% lidocaine without epinephrine was injected, followed by application of pulsed radiofrequency for 180sec at 42°C by radiofrequency (radiofrequency generator system BMS-50N, Bramsys).
