Nano-PFC functions to accelerate bone fracture healing. a A flow chart showing the overall experimental procedure. b The radial radiographs of representative animals in each group showing the healing progression over time (n = 3). Red arrowheads point at the fracture regions. c Femandez-Esteve and d Lane-Sandhu scores for the quantitative determination of bone healing progression. ^#P < 0.001, compared to the control group at the according time points
