Abstract
An ORIF implant has an electronics module with a stimulus light and optical sensors for sensing fluorescent emissions coupled to a near-field digital radio. The implant is used with a near-field radio to receive a sequence of fluorescent emissions readings from the implant into a processor that fits the sequence of readings to a bone-specific kinetic model that is a superposition of a plug flow model of periosteal perfusion and a two-compartment model of endosteal perfusion of perfusion of bone. A system for use during ORIF surgery has an injector for fluorescent dye, a camera to send a sequence of images of fluorescent emissions from fluorescent dye in a bone of a subject to an image processor when the bone is illuminated with a stimulus light, the processor configured to fit the sequence of images to a model of perfusion of bone.
