Status: Enrolling

Conditions: Rotator Cuff Tear Arthropathy; Post Operative Pain

About

The purpuse of this study is to asses if the pulsed radiofrecuency of the supraescapular nerve and accesory nerve have the same or superior efectivity controlling the acute postoperative pain than interscalenic braquial plexus block

Full description

This is a randomized, double-blind trial that compares the effect in postoperative pain of pulsed radiofrecuency of the supraescapular nerve carried out at least two to four weeks before reverse total shoulder arthroplasty surgery with interscalenic braquial plexus block done at the moment of the surgery. All the patients received conventional general anaesthesia and multimodal postoperative analgesia with additional patient-controlled rescue analgesics were prescribed
