Arthroscopic Treatment of Suprascapular Neuropathy from a Suprascapular Notch Cyst Using a Lateral Subacromial Approach

Abstract

We describe a safe surgical technique for arthroscopic decompression of a suprascapular notch cyst in the setting of compressive suprascapular neuropathy. Position the patient in the standard beach-chair position. Palpate and mark the subcutaneous landmarks of the shoulder in preparation for later arthroscopy. Create standard anterior and posterior portals for glenohumeral visualization. Establish accessory superior and lateral portals and transition to a lateral viewing portal to perform suprascapular notch decompression. Establish a G Portal and release the transverse scapular ligament using arthroscopic scissors. Perform arthroscopic lavage of the subacromial space and glenohumeral joint and close arthroscopic portals. As suprascapular nerve entrapment is a relatively rare entity, with only a limited number of studies from which to draw conclusions regarding the outcomes of arthroscopic suprascapular nerve release, Shah et al. recently reported on their results in twenty-four patients using this surgical technique.IndicationsContraindicationsPitfalls & Challenges.
