Can a gentle electrical current reveal hidden tissue damage after a broken bone?
NCT ID NCT06858488
First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time
Summary
This pilot study explores whether an electrical impedance tomography (EIT) device can detect soft tissue injury in adults who have suffered high-energy fractures of the arms or legs. Participants will undergo EIT imaging in the emergency department, operating room, clinic, and hospital room. The goal is to see if changes in electrical signals through the tissue can help doctors assess injury severity and readiness for surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- electrical impedance tomography (EIT) device
- What this could lead to
- If successful, this imaging technique could help doctors better assess soft tissue damage and decide the right time for surgery after severe fractures.
- What could go wrong
- This is a small pilot study with only 30 participants, focused on feasibility. The device may not prove useful for guiding treatment decisions.
