Abstract:
Objective To study the method of solving the complications of large allograft including resorption, nonunion and refracture by means of vascularization and the way of improving bone healing. Methods The bone defect longer than 10 cm of limbs were found in 21 cases, plate or external fixator were used to fix allograft bone, and then vascularied autologous bone or periosteum were transplanted or inserted to the massive allograft In order to vascularizate allograft, improve bone healing and prevent complications of bone resorption and osteolysis. 4 cases were implanted by local vascular bondle in one end. 4 cases were transplanted vascular iliac bone into middle part the allograft bone, 2 cases were into one end. 2 cases were transplanted by vascular fibular bone. 6 cases were used vascular periosteum. 3 cases were used combined methods. Results Twenty-one cases with 10 cm or more bone defect in this group were treated by the method above. 14 cases were achieved primary healing, 6 were healing by farther operation, 1 failure. Complications were found in 7 cases, 4 occur infection in all. All were achieved satisfactory function and outlook by follow-up. Conclusion The method of vascularied autologous bone or periosteum combined with massive allograft are effective to improve bone union, reduce the complication of bone resorption and osteolysis,which proved usefull to treat large bone defect.
