The incidence of the interochanteric fracture of femur is increasing and this increase is likely to continue for many years due to increase of traffic accident and old people. The primary goal in the treament of an elderly patient with an intertrochanteric fracture is to return the patient to his prefracture activity as soon as possible. Rapid mobilization of a pain free patient helps to prevent skin ulceration, pneumonia, urinarystasis, thromboembolic disease and other complications of confinement to bed in the eldery. For there reasons, treatment of intertrochanteric fractures by surgical methods has become the standard procedure. The authors treated 53 cases of intertrochanteric fractures from March 1978 to February 1985 with Ender nail or sliding screw plate. The results obtained as follows: l. In the 34 cases where sliding screw plates were used, the patients average age was 49.4 years old and in the 19 cases where Ender nails were used, the average in age was 63.2 and therefore, compared to the sliding screw plate, the patients using Ender nails were about 13.8 years older. 2. In the cases where Ender nails were used, the average operation hours took in the average of 55 minutes and whereby, in the cases where sliding dcrew plates were used, took in the average of 125 minutes, and during the operation time, the amout of hemorrhage in the cases of Ender nail was about 150ml and the sliding scew plate resulted in about 610ml. 3. The average weight bearing period in the cases which Ender nails were used took in the average of 2.5 weeks, where by the sliding scew plates took in the average of 9.8 weeks. 4. In the cases where Ender nails were used, the radiological bony union time was about 12.7 weeks and the sliding screw plate took about 16.1 weeks. 5. In the cases of Ender nail, if, in the geriatric age, the indication is chosen well, it will result in a benefial treatment method.
