Abstract:
In order to explore the effect of anti vegf on fracture healing process,rabbits with left radius fracture were used as an animal model and divided randomly into control and experiment groups.VEGF polyclonal antibody was given to the animals of the experiment group films were thken at the fracture sites after 1,3,5 and 8 weeks of the fracture.the results showed that the cellular necrosis increased in the experiment group shortly after the fracture.Although there was fibroblast proliferation at 72 hours after the fracture,continuous focal necrosis was seen from 1 to 5 weeks in the fracture sites,and the vascularization reduced obviously 3 weeks after the injury.The organelle degeneration was observed in the fibroblasts and osteoblasts under microscope.The fracture sites were filled with fibrous tissue at the 8 th week and nonunion was ween in the fracture sites on X ray films.These results suggest that the lack of VEGF in the fracture sites might be one of the important reasons of fracture healing.
