Ultrasound-guided cervical selective nerve block: A case series.

BACKGROUND

Cervical radiculopathy is characterized by pain, numbness, tingling, and weakness, mostly in an affected extremity, reflecting compression of a nerve in the neck is compressed or irritated where it emerges from the spinal cord. Diagnosis requires a detailed anamnesis, physical examination, and imaging. Physical therapy, exercise, medical therapy, and injections are the preferred treatments, but injections into the cervical region are only indicated if conservative treatment is ineffective.

OBJECTIVE

This study explored the utility of selective cervical nerve root blocks (SNRBs) performed at various levels under ultrasound guidance (USG).

METHODS

We evaluated patients diagnosed with cervical radiculopathy via physical examination and magnetic resonance imaging from November 2019 to March 2020. We included those who did not respond to conservative treatment and therefore received SNRBs at various levels. Sixty-three patients were evaluated over 6 months in terms of pain, functional status, and complications.

RESULTS

We retrospectively evaluated patients with cervical herniated discs who received SNRBs at various levels between C4-7 under USG. Pain and functional status improved in month 1 and was maintained until at least month 6.

CONCLUSION

SNRB injections performed under USG effectively treated pain and poor functional status in selected patients. The procedure is safe (especially) for patients who do not respond to conservative treatment.
