Open Fracture Cohort
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.
Immunofluorescence Imaging: Patients will be administered FDA approved ICG through intravenous injection and imaged by a FDA approved surgical microscope (Pentero or 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.

Complication Cohort
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
