Suprascapular Nerve Entrapment

Abstract

Suprascapular neuropathy can be caused by a variety of anatomic and pathologic entities as the nerve courses from the brachial plexus through the suprascapular and spinoglenoid notches to innervate the supraspinatus and infraspinatus muscles. We describe techniques for arthroscopically accessing the nerve at both the suprascapular and spinoglenoid notches and decompressing structural lesions that may be contributing to the neuropathy.
