Treatment for rib fractures using cryoneurolysis

Treatment of Adult Traumatic Rib Fractures With Percutaneous Cryoneurolysis for Pain Control (Trauma-PC2-study)

Not applicable Interventional Stanford University · NCT05330611

This study is testing a new pain relief method using cold therapy for adults with rib fractures who can’t have surgery to see if it works better than regular pain treatment.

What this trial studies

This research examines the effectiveness of the Iovera Smart Time 190 device for ultrasound-guided cryoneurolysis in trauma patients aged 18-64 with rib fractures who are not candidates for surgical stabilization. The study compares the pain relief outcomes of patients receiving cryoneurolysis of the intercostal nerves against those receiving standard multimodal pain therapy. The goal is to provide both short and long-term pain control while the rib fractures heal.

Who should consider this trial

Good fit: Ideal candidates are trauma patients aged 18 to 64 with acute rib fractures between ribs 3 and 9 and a pain score of 5 or greater.

Not a fit: Patients with rib fractures requiring surgical stabilization or those with contraindications to cryoneurolysis will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve pain management for patients with rib fractures, enhancing their recovery experience.

How similar studies have performed: While the use of cryoneurolysis is established, this specific application for rib fractures is novel and has not been extensively tested in prior studies.
