    Figure 1.

    The anatomy of the suprascapular nerve (SSN). The SSN arises from the C5 and C6 nerve roots, emerges from the superior trunk of the brachial plexus, and then enters the supraspinatus fossa via the suprascapular notch underneath the superior transverse scapular ligament.

    M, muscle; N, nerve.

    Figure 2.

    Ultrasound of the suprascapular region identifying the following structures: the trapezius muscle, supraspinatus muscle, suprascapular notch, transverse scapular ligament, and the suprascapular nerve.

  • Figure 3.
    Figure 3.

    A: The letter A indicates the area for the suprascapular vessels; the letter B indicates the transverse scapular ligament. B: With application of color Doppler. The suprascapular nerve (indicated by the arrow) can be visualized medial to the pulsation of the suprascapular artery as an oval or round slightly hyperechoic structure.

    Ultrasound showing local anesthetic (LA) injection. The needle is advanced using an in-plane approach. After negative aspiration, 10 mL of ropivacaine 0.5% is injected, and the spread of the local anesthetic is confirmed as a separation between the supraspinatus muscle and the spine of the scapula.
