Osteosynthes is by percutaneus intramedullary nailing using multiple pinning of K-wires or rush pins were performed for six patients above 65 years old who sustained distal femoral fracture. Four of them acquired good and early bony union. Two of them acquired good range of motion of the knee.
Advantages of these methods for old patients are as follows.
First, the invasion of these methods is little for the femoral condyles that are fragile due to osteoporosis. Second, the invasion of these methods for muscles around the knee joint is little. Third, it is easy even for old patients to acquire early bony union, because there is no invasion on the periosteal membrane by these methods. Forth, required time for these operations is short and bleeding is a little.
Therefore, these methods are very useful for distal femoral fracture for old patients whose range of activity is less than that of young people.
