Abstract

Jones fractures of the proximal fifth metatarsal carry a significant risk of nonunion, which greatly increases the burden on patients. A significant reason for this fracture’s poorer outcomes is the lack of blood flow in the region it occurs. We will apply our newly developed co-registered speckle contrast and frequency domain-diffuse optical tomography system to monitor the Jones fracture region in healthy subjects under and over 50 years of age. The information collected will provide baseline data for future fracture healing outcomes research and provide insight into whether the poorer healing outcomes of older individuals are related to baseline hemodynamics.
