New hope for stubborn elbow and foot pain? tiny particles block pain signals
NCT ID NCT06523114
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a procedure called transcatheter arterial embolization (TAE) in 12 people with long-term elbow or foot pain that didn't get better with usual treatments like physical therapy or medication. The procedure uses tiny particles to block abnormal blood vessels thought to cause pain. Researchers measured pain levels and side effects over 12 months to see if TAE is safe and effective.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Transcatheter arterial embolization (a procedure using tiny particles to block abnormal blood vessels)
- What this could lead to
- If it works, this could offer a new pain relief option for people with stubborn elbow or foot pain who haven't gotten help from standard treatments like physical therapy or medication.
- What could go wrong
- This is a very small study with only 12 people and no comparison group, so results may not apply to everyone. The procedure also carries risks like bleeding or infection.
