Abstract

PURPOSE: To evaluate the risk factors of sliding after internal fixation with sliding compression hip screw in stable intertrochanteric fracture of the femur.
MATERIALS AND METHODS
From March 2000 to April 2003, 61 stable intertrochanteric fractures (Kyle-Gustilo type II) were treated operatively with sliding compression hip screws. The patients were 40 females and 21 males with an average age of 74 (range, 54~99). We measured vertical and horizontal shortening in regard to age, sex, bone mineral density, neck-shaft angle, cancellous bone defect, and the existence of lessor trochanter fracture on postoperative 6 months.
RESULTS
The average vertical shortening was 4.1 mm (0~22 mm) and the average horizontal shortening was 7.3 mm (0~30 mm). Age, sex, bone density and neck-shaft angle were not significantly related with vertical and horizontal shortening (p>0.05). Vertical shortening was significantly greater in the group with cancellous bone defect and in the group without lesser trochanter fracture (p<0.05).
CONCLUSION
Proper management for fracture site and fixation was needed to make it stable because the stable intertrochanteric fracture with cancellous bone defect and intact lesser trochanter could be induced into unexpected sliding.
