Objective To construct goat tibial diaphyseal defect model by using half-ring sulcated external fixator. Methods Nine goats were divided into three groups. The 20 percent single tibial diaphyseal defect of every goat was made and fixed with half-ring sulcated external fixator. Animals in each group were killed respectively at 5
th
10
th
15
th
week postoperatively. Bone formation was evaluated by X-ray and histology. Results The fixity was stable in goat tibial diaphyseal defect. No bone repair was found at the 5
th

th
15
th
week postoperatively and sclerization at the broken ends of the fractured bone was observed at the 15
th
week postoperatively but no bone formation was found. Conclusion Half-ring sulcated external fixator is a fair
apparatus in constructing long bone defect model for tissue engineering repairing study and 20 percent goat tibial diaphyseal defect cannot be repaired by itself.
