Abstract

Jones fractures, which occur in the proximal fifth metatarsal of the foot carry a significant risk of nonunion. Nonunions increase the patient’s financial burden, risk of infection, and may take years to heal completely. Exploiting the fact that a reason for this higher risk of nonunion is inadequate blood supply, we will use diffuse optics to monitor the fracture healing process. We recently developed a speckle contrast optical tomography system which we will combine and co-register with a frequency domain-diffuse optical tomography system. This combination will provide a powerful instrument optimized for monitoring patient risk of nonunion during fracture healing.
