Suprascapular Nerve Block
The suprascapular nerve, due to its superficial location in the supraspinous fossa, is a readily accessible nerve that is easy and safe to block. The suprascapular nerve block (SSNB) has been utilized for well over 60 years to address various causes of shoulder pain. Early advocates of the SSNB reported its usefulness in treating shoulder pain secondary to rotator cuff degenerative tears. Subsequent studies expanded its indications to include conditions such as glenohumeral degenerative joint disease, adhesive capsulitis, and postoperative shoulder pain following arthroscopic surgery. The technique of the SSNB has evolved over the years. Early reports favored blocking the suprascapular nerve at the suprascapular notch; however, more recent advocates suggest blocking the nerve at the supraspinous fossa to minimize the risk of major complications.
