Evaluating ultrasound-guided cervical joint injections for neck pain
The Incidence of Inadvertent Intravascular Injection During Ultrasound-guided Cervical Medial Branch Blocks: a Fluoroscopically Controlled Study
Montreal General Hospital · NCT06731920
This study is testing if using ultrasound to guide neck injections can help prevent problems from hitting blood vessels in people with neck pain.

What this trial studies
This observational study investigates the safety of ultrasound-guided cervical medial branch blocks (CMBB) in patients with cervicalgia. It aims to determine the frequency of intravascular injections during these procedures, which can lead to false negative diagnostic results. By utilizing digital subtraction angiography (DSA), the study will assess the effectiveness of ultrasound guidance in avoiding blood vessels during needle placement. The findings could provide valuable insights into the safety and efficacy of this newer imaging technique compared to traditional fluoroscopy.
Who should consider this trial
Good fit: Ideal candidates for this study are consenting patients over 19 years of age who are undergoing ultrasound-guided cervical medial branch blocks as part of their usual care.
Not a fit: Patients with known bleeding disorders, those on certain anticoagulant medications, or individuals unable to visualize targeted structures on ultrasound may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance the safety of cervical joint injections, leading to more accurate diagnoses and better management of neck pain.
How similar studies have performed: Previous studies have suggested a lower incidence of vascular breach with ultrasound guidance, indicating potential success for this approach, though further confirmatory studies are needed.
