ICG fluorescence imaging to show bone blood flow in open fractures and infections
Official title: Prospective Observational Study of ICG Fluorescence Imaging in Open Fracture and Infection Patients: Early Comparison With a Novel Imaging Device
Run by Dartmouth-Hitchcock Medical Center · NCT06793644 · Data updated 2026-11-12
This will test whether a dye-based fluorescence camera can show bone blood flow in adults with open fractures or bone infections so surgeons can choose the best treatment.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older with open extremity fractures or fracture-related bone infections who are scheduled for surgical fixation, fusion, or debridement and can give informed consent are ideal candidates.
✕Probably not a fit
Patients with hand fractures, iodine allergy, burns at the fracture site, or those unable to provide consent — as well as patients not undergoing planned surgical care at the site — are unlikely to benefit from this imaging approach.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational study uses indocyanine green (ICG) fluorescence imaging (cBPI system) during planned surgical care to visualize bone perfusion in adults with open extremity fractures or fracture-related infections. Participants 18 and older who are undergoing external or internal fixation, joint fusion, or debridement will receive the imaging during their routine operative procedures without changing standard treatment. Patients with hand fractures, iodine allergy, or burns at the fracture site are excluded. The goal is to correlate the imaging findings with bone health and healing potential to inform future surgical decision-making.
Why it matters
Potential benefit: If successful, surgeons could use real-time images of bone blood flow to pick treatments that lower complication risk and improve healing.
How similar studies have gone: ICG fluorescence is well established for soft-tissue perfusion imaging, but its application to bone blood flow is relatively novel and supported mainly by limited pilot and feasibility data.
