In unstable femoral trochanteric fracture, we usually used transversing K-wires through the lesser trochanter to achieve an anatomical reduction, and using sliding hip screws. However, in patients with comminuted lesser trochanter or osteoporosis, an intrusion of the wire into the lesser trochanter and/or iatrogenic intertrochanteric fractures were often resulted. Those who were not familiar with a technique of puncturing two holes through the lesser trochanter might have had to face some difficulties. In order to overcome aforementioned drawbacks, the authors had quite satisfactory results by employing the method of passing each of two wires above and below the iliopsoas muscle, and they were twisted posteriorly and then anteriorly; and finally they were pulled together posteriorly. Through this technique, both firm fixation of the lesser trochanter and more stable bony union were obtained.
