RESUMO
<p><b>OBJECTIVE</b>To investigate clinical outcomes of Kirschner wire as blocking screws combined with interlocking intramedullary nail internal fixation in treating tibial metaphyseal fractures (AO 43A).</p><p><b>METHODS</b>From March 2011 to June 2012, 9 patients with tibial metaphyseal fractures were treated with blocking screws Kirschner wire combined with interlocking intramedullary nail, including 7 males and 2 females aged from 23 to 54 years old with an average of 37.4. Postoperative complications, X-ray were observed, AOFAS scoring were used to evaluate function after operation at 12 weeks.</p><p><b>RESULTS</b>All patients were followed up from 6 to 40 weeks (mean 20.1), and healed at stage I. No serious swelling, infection and skin necrosis occurred. No fracture instability and displacement appeaered at 4 and 8 week after operation. AOFAS score was (95.2±4.6) at 12 weeks after operation and 7 patients gained excellent result and 2 patients good.</p><p><b>CONCLUSION</b>Kirschner wire as blocking screws with interlocking intramedullary nail for treatment of tibial metaphyseal fractures can fix well and perform simply.</p>
