NCT03478735

Brief Summary

This study will compare the analgesic benefit of a traditional landmark-guided GON block with the ultrasound-guided approach over a four week period in patients with occipital neuralgia or cervicogenic headache.

Outcome Measures

Primary Outcomes (1)

  • Change in Numeric Rating Scale (NRS) Pain Score

    Pain intensity will be assessed using a NRS marked from 0-10 with fixed intervals, with 0=no pain, and 10=worst pain.

    baseline, 4 weeks

Secondary Outcomes (3)

  • Change in number of patients with medication overuse

    baseline, 4 weeks

  • Change in number of headache days per month

    baseline, 4 weeks

  • Change in Headache Impact Test (HIT-6) Score

    baseline, 4 weeks

Study Arms (2)

Ultrasound Guided GON Block at C2

EXPERIMENTAL

Ultrasound Guided Greater Occipital Nerve Block at C2

Procedure: Ultrasound Guided Greater Occipital Nerve Block at C2

Landmark based GON Block

ACTIVE COMPARATOR

Landmark-Based Greater Occipital Nerve Block

Procedure: Landmark-Based Greater Occipital Nerve Block

Interventions

Ultrasound guided injection

Ultrasound Guided GON Block at C2

Traditional landmark-guided technique at the superior nuchal line. This approach relies solely on superficial bone-based anatomic landmarks to infiltrate local anesthetic and corticosteroid around the nerve at the level of the superior nuchal line.

Landmark based GON Block

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Unilateral or bilateral headache symptoms attributed to occipital neuralgia or cervicogenic headache as defined by the International Headache Society's International Classification of Headache Disorders (3rd edition beta version)
  • Age 18 years and older (no upper age limit defined)
  • Imaging of cervical spine within last year (either x-ray, MRI or CT)

You may not qualify if:

  • History of cervical spine surgery, trauma, or surgical procedure involving head or neck during the last year
  • Use of new preventative medications 1 month prior or during study enrollment
  • Evidence of impaired sensation in the GON dermatome region (posterior scalp to the vertex of the cranium) from neurological, dermatological, or other disease process
  • Evidence of cranial defect or other anatomical abnormality near the target injection site
  • History of bleeding diathesis, coagulopathy, or current use of anticoagulant medications
  • Pregnancy
  • History of adverse reaction or allergy to local anesthetic agents or corticosteroids
  • Occipital nerve block within the past three months.
  • Unavailability for appropriate follow-up throughout the whole duration of study
