Effect of Radiofrequency of Suprascapular Nerve in Shoulder Reverse Arthroplasty

Study Overview
=================
Brief Summary
-----------------
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

Detailed 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

Official Title

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Visual analogical scale | Postoperative acute pain measurement. From 0 to 10, Zero means no pain and ten would be the worse pain that the paitient could feel. | periodical measurements of pain, inmediate preoperative pain up to three months postoperative | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Visual analogical scale | chronic pain after surgery. From 0 to 10, Zero means no pain and ten would be the worse pain that the paitient could feel. | 3 months postop. until 1 year postop |
