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

INTRODUCTION: We describe a safe surgical technique for arthroscopic decompression of a suprascapular notch cyst in the setting of compressive suprascapular neuropathy. STEP 1: POSITION THE PATIENT: Position the patient in the standard beach-chair position. STEP 2: MARK ANATOMIC LANDMARKS: Palpate and mark the subcutaneous landmarks of the shoulder in preparation for later arthroscopy. STEP 3: DIAGNOSTIC ARTHROSCOPY: Create standard anterior and posterior portals for glenohumeral visualization. STEP 4: PERFORM SUPRASCAPULAR CYST DECOMPRESSION THROUGH A LATERAL SUBACROMIAL APPROACH: Establish accessory superior and lateral portals and transition to a lateral viewing portal to perform suprascapular notch decompression. STEP 5: RELEASE THE TRANSVERSE SCAPULAR LIGAMENT: Establish a G Portal and release the transverse scapular ligament using arthroscopic scissors. STEP 6: CLOSURE: Perform arthroscopic lavage of the subacromial space and glenohumeral joint and close arthroscopic portals. RESULTS: 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.
