Abstract:
Objective To investigate the difference between anagenetic fibula with normal fibula in mechanical parameters, osteogenesis and tissue morphology,through establishing the model of fibula defect in rabbit.Methods Twenty New Zealand white rabbits were randomly divided.Model group were cuted the right fibula bone with 1.5 cm length.X-ray was used to observe the anagenetic fibula(half month,one month,two months).Stumped the anagenetic and normal fibula(1.5 cm)after two months. Three-point bending test was used to test the mechanical properties;alkaline phosphatase staining was checked the bone-formation ability;HE staining to check the tissue morphology.Results After half month a few new bone were formed at the edges of resec-tion area,one month later new bone were growed in the donor site,and after two month new fibula were completely formed.The three point bending test of fibula showed:there was no statistically significant difference between anagenetic fibula and normal fibu-la(P >0.05);alkaline phosphatase staining and HE staining showed the anagenetic fibula bone forming ability,histology had no sig-nificant difference compared with normal fibula.Conclusion Fibula were regenerated successfully after removing which retaining the periosteum.Compared with the normal fibula,there were no remarkable differences in mechanical parameters,osteogenesis and tissue morphology.
