Interlocking intramedullary nail fixation for comminuted fracture of femoral shaft

Objective To study the effect of interlocking intramedullary nail for comminuted fracture of femoral shaft. Methods 67 cases with fractures of femoral shaft were treated with interlocking intramedullary nail fixation through anterolateral approach by canal reaming and static fixation. Results 67 cases were followed up for 6 - 28 （ 16 ± 8） months. The incisions got primary healing. 63 cases got bony union in 4 - 8 months. 4 cases was changed into dynamic fixation in 4 months after the operation,and healed after 11 months. No complication was found. The function of knee joint were evaluated according to the estimation standard of Merchant, and it was excellent in 43 cases, good in 19, fair in 4 and poor in 1 ,and the rate of excellent and good was 92.5%. Conclusions The effect of interlocking intramedullary nail for comminuted fracture of femoral shaft was satisfying.
