Modified Lateral Block of the Suprascapular Nerve: A Safe Approach and How Much to Inject? A Morphological Study

Abstract

Based on this cadaver study, the lateral modified approach appears to be a safe technique for a suprascapular nerve block, which might be preferred as a single shot technique. A 5 mL volume appears sufficient to fill the supraspinous fossa and to reach the suprascapular nerve, which branches in this anatomical compartment.
