An observational study in Fractures, Bone and Trauma Injury, sponsored by Dartmouth-Hitchcock Medical Center. Recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-03-19.
Sponsored by Dartmouth-Hitchcock Medical Center · Observational
The purpose of this study is to determine whether an indocyanine green (ICG) fluorescence imaging system (cBPI) can be used to provide surgeons with information about bone health or bone blood flow. This will help surgeons better understand the healing potential of bone and relative risk of complication. This is important to help surgeons select the most appropriate treatment for severe traumatic injuries and infections.

Patients 18 years of age or older who present with an open fracture or fracture related infection.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Patients 18 years of age or older. Extremity fracture. Prior definitive fracture management with external fixation, internal fixation, or joint fusion. Superficial, deep, or organ space SSI (as per CDC criteria) at the fracture site that requires operative management. Will have all fracture care surgeries performed by a participating surgeon or delegate. Provision of informed consent
Drug: Immunofluorescence Imaging
Patients 18 years of age or older. Open extremity fracture. Planned definitive fracture management with external fixation, internal fixation, or joint fusion. Open fracture wound management that includes formal surgical debridement within 72 hours of their injury. Will have all planned fracture care surgeries performed by a participating surgeon or delegate. Provision of informed consent.
Drug: Immunofluorescence Imaging
Patients will be administered FDA approved ICG through intravenous injection and imaged by a FDA approved surgical microscope (Spy Elite) which is 0.5 meter away from the subject. Both ICG fluorescence and the two imaging systems have been used for routine clinical practice for many years. Figure (a) shows the Schematic sketch of the imaging systems. ICG fluorescence imaging utilizes intravenously injected ICG, which is a fluorescent dye that is FDA-approved for clinical use, illuminated with near-infrared light. The ICG dye is indirectly activated and the dynamic fluorescence due to bone perfusion can be captured by a video rate imaging system.
Number of participants who undergo an unplanned fracture-related reoperation
All unplanned reoperations will be documented using a specific case report form
Time frame: 12 Months
Number of participants who experience a post-procedure surgical site infection
Post-procedure surgical site infection using Centers for Disease Control criteria will be documented at each follow-up
Time frame: 12 Months
