Arthroscopic Suprascapular Nerve Decompression: Etiology, Diagnosis, and Surgical Technique

Abstract

Although entrapment of the suprascapular nerve is an uncommon source of shoulder pain, proper diagnosis and treatment are critical to maintain function, reduce or eliminate pain, and prevent chronic atrophy of the supraspinatus and infraspinatus. In this article, we present an arthroscopic technique for suprascapular nerve decompression at the spinoglenoid notch or suprascapular notch, either through the subacromial space or glenohumeral joint. These methods allow for facile decompression of the suprascapular nerve and direct visualization of the medial neck of the glenoid to avoid complications from iatrogenic nerve injury related to aggressive dissection of the medial capsule.
