LKnative - Suprascapular nerve block

9 – Sonoanatomy: Supraspinatus approach to block the suprascapular nerve ultrasound-guided

Sonographically, the suprascapular nerve is seen as a flattened, hyperechoic structure in the bony groove of the scapular notch underneath the superior transverse scapular ligament (not visible with ultrasound)

Color Doppler can be used to visualize the vessels superficial to the ligament
