RESUMO
<p><b>OBJECTIVE</b>To explore the method and effect of inter-locking intramedullary nail and tripus in closed reduction for treating tibial fracture.</p><p><b>METHODS</b>One hundred and twenty-six patients of tibial fractures were treated by inter-locking intramedullary nail and tripus in closed reduction. There were 76 males and 50 females aged from 25 to 68, the mean age was 38; There were 86 close fractures and 40 open fractures (Gustilo I and II type). AO classification system was used for all cases, fracture type A in 49 cases, type B in 41 cases, type C in 36 cases.</p><p><b>RESULTS</b>All patients were followed up for 10 to 16 months. Fratures were cured, according to the criteria of Johner-Wruhs, the results were excellent in 103 cases, good in 18 cases, fair in 5 cases.</p><p><b>CONCLUSION</b>Inter-locking intramedullary nail is the optimal operation method in treating tibial fracture. Static locking should be a routine way, and closed reduction, no stripping periosteum, infectious rate and complications are reduced. Through tripus work intensity are reduced and reduction easily during operation.</p>
