MRI and clinical study of an easy and safe technique of suprascapular nerve blockade.
Suprascapular nerve block is used with increasing frequency by anaesthetists and rheumatologists in the management of shoulder pain from a variety of disorders. In the classical technique, the needle is introduced into the supraspinous fossa perpendicular to the blade of the scapula and then is moved to enter the scapular notch, with the risk of pneumothorax or damage to the suprascapular nerve or vessels. However, it is not necessary to locate the scapular notch in order to perform this block. Introducing the needle parallel to the blade, i.e. away from the direction of the lung and the suprascapular nerve and vessels, and injecting the solution into the floor of the supraspinous fossa is an easy and safe technique. We report the results of a MRI and clinical study that confirm the efficacy of this approach.
