: Techniques and Outcomes The suprascapular nerve block (SSNB) is discussed in the literature but not widely adopted as a treatment option for certain shoulder conditions such as adhesive capsulitis or shoulder dislocation. In todays post, we will briefly review the anatomy, discuss the technique and review some of the literature on the indications. "Suprascapular neuropathy: what does the literature show?."

It moves across the superior border of the scapular into the suprascapular notch (the target of the block) where it is maintained by the transverse scapular ligament. From there it courses inferiorly to the spinoglenoid notch.The suprascapular notch innervates two muscles: the supraspinatus and infraspinatus.
