The goal of our study was to evaluate the usefulness and results of the Interlocking Compression Nail in femoral shaft stable fractures.

The 87 patients, 88 cases, who were underwent internal fixations with interlocking compression nail for the stable fracture of the femoral shaft were evaluated. The majority of the causes of injury was traffic accident and the majority of location of the fractures was middle one thirds. The classification of the fracture using Winquist-Hansen classification showed that grade 0 were 23 cases(26.1%), grade 1, 47 cases(53.4%) and grade 2, 18 cases(20.5%). We used ICnail(Osteo, Switzerland) that can actively compress the fracture gap, maximum 10mm.

We used active compression in 63 cases(71.6%) and the mean length of compression was 2.3mm(range 1-5mm). The bone union was seen in 63 cases(71.6%) at postoperative 4 months and in 87 cases(98.9%) at postoperative 6 months. There was one case of delayed union, but there were no nonunion, infection, leg length discrepancy, and angular or rotational deformity, disturbing the daily activity.

The interlocking compression nail can reduce the fracture gap easily and effectively using compression screw by active interfragmentary compression. Thereby promote fracture healing and postoperative stability at the fracture site can be obtained, so early weight bearing is possible. Especially, this is recommendable useful method for femoral shaft stable fracture.
