The treatment of trochanteric femoral fractures is still somewhat controversial. The general aims, however are to minimize oprrative and postoperative complications and to achieve early ambulation The authors treated 23 cases of intertrochanteric fractures from January 1985 to December 1989.

The results were as follows :

1. Among 23 patients the ratio of male & female was almost even and the averge age was frequent cause.

2. There were 19 cases of fall down about the causes of the fractures and it was most frequent cause.

The classification of the fractures were 10 Tronzo type III. 6 Tronzo type II, and 5 Tronzo type IV.

3. There were 17 cases which were performed the operation within 2 weeks from trauma to operation and the operation time were ronsumed for the 19 closed intramedullay nailing about an hour and for the 4 cerclage wiring about 2 hours.

The bleeding loss was from 30ml to the 1050ml.

4. The postoperative weight bearing period was performed the partial weight bearing the next day of the operation for the stable fractures, and the long brace appling after 2 weeks of the operation for the unstable fractures.

5. The most common complications were the knee pain and the mild knee stiffness.

6. The authous peformed 4 cerclage wiring in case of severe comminuted fracture which we thought the difficulty of the postoperative stability and in case of the fracture line was remained unstable by the closed intramedullary nailing.

Recently we performed 9 cases with using Rush nail. Staple or K-wire to prevent the downard displace of the nail for the inserted site.

Throughout these operation we consider this is the excellent treatment method for the old partients by the reinforcement of the several disadvantage of Ender nail.
