The incidence of intertrochanteric fracture of femur is much higher than past because of recent prolongation of average life span and increased activity. The goal of treatment of an intertrochanteric fracture must be restoration of the patient to his or her preoperative status at the earliest possible time.
The authors analysed the 51 patients of the intertrochanteric fracture over 65 years old age who were operatively treated from Jan. 1989 to Dec. 1994.
The results obtained were as follows 1. According to Tronzo classiffication, the most common type was type 3 in 3B cases (61%), and according to Evans classification, unstable fracture were more common (65%).
2. The degree of osteoporosis by Singh index were 27 cases (53%) in Grade III, 15 cases (29%) in Grade II, 7 cases (14%) in Grade IV, and 2 cases (4%) in Grade V. The osteoporotic group (Singh index I, II, III) had statistically significant correlation with unstable type fracture.
3. The patterns of reduction were anatomical reduction in 33 cases (66%), and valgus reduction (9 cases ; 18%), varus reduction (6 cases ; 12%), medialization (2 cases ,4%).
4. The mean union time was 14.1 weeks on compression hip screw group, and 15.7 weeks on Ender nail group, 15.4 weeks on Gamma nail group, 16.2 weeks on multiple pinning gloup. The authors couldnt find significant difference among the each groups.
5. Postoperative complications were occurred in 23 cases(45%) and more frequently in unstable type fracture(19 cases).
With the age of our population advancing, the number of elderly osteoporotic patients with comminuted intertrochanteric fractures of the femur has increased dramatically. Intertrochanteric fractures of the femur usually occur in a more elderly age group than femoral neck fractures of the femur usually occur in a more elderly age group than femoral neck fractures. Intertrochanteric fractures are best treated by intenal fixation, since this mehod provides satisfactory positioning of the fragments and obviates the hazards of recumbency. However, in some caces with severe osteoporosis, arthroplasty is an excellent altemative to the internal fixation.
From 1987 to 1992, thirty-six intertrochanteric fractures of femur in the elderly patients(over 60 years of age) were treated by operation at the department of orthopaedic surgery in the Ewha Womans University Hospital. Thirty-three caces were internally fixated with the sliding-compression hip screws-plates(30), the Gamma interlocking intramedullary nails(2), the Rohs plate(1), and in three caces endoprosthetic or total hip replacement arthroplaties were performed.
