摘要
laterals or femoral head and neck of 18 mature healthy male domestic dogs were divided into two groups by the principle or auto-control.Avascular osteonecrosis of femoral head(ONFH)and old femoral neck fracture(FNF)were made respectively.Free vascularized fibula grafting was performed 2 weeks later.Arter operation, X-ray,histopathological,electron microscopic,tetracycline fluorescence labelling and99mTc-methylene diphosphorate scanning were carried out respectively.The result indicated that free vascularized fibula grarting could provide new blood supply system to injured femoral head and participate in the repairing process of avascular uecrosis of femoral head.
