- PURPOSE
To establish the incidence, type and significance of knee instability in patients with ipsilateral femoral and tibial shaft fracture, comparing with the patients with femoral shaft or tibial shaft fracture alone.
MATERIALS AND METHODS
Two hundreds and seventy-nine consecutive patients were retrospectively reviewed from February 2000 to April 2004. They were composed of 80 patients with femoral shaft fracture alone, 176 patients with tibial shaft fracture alone and 23 patient with ipsilateral femoral and tibial shaft fracture. We evaluate the instability of knee based on physical examinations, plain stress films and MRI. We analyze incidence and period to diagnosis of instability, period to complete bony union and Hospital for Special Surgery (HSS) knee score respectively.
RESULTS
There were 6.3% of knee instability in femoral shaft fracture alone, 9.7% in tibial shaft fracture alone and 30.4% in ipsilateral femoral and tibial shaft fracture. The average period to diagnosis of instability, average period to complete bony union and average HSS knee score were 9.2 months, 4.7 months and 65 points in femoral shaft fracture alone, 9.1 months, 4.2 months and 69 points in tibial shaft fracture alone, 8.7 months, 5.3 months (femur), 4.7 months (tibia) and 57 points in ipsilateral femoral and tibial shaft fracture respectively.
CONCLUSION
We should consider MRI to evaluate the knee instability in patient with ipsilateral femoral and tibial shaft fracture at the time of injury and make a plan early about the treatment of knee instability.

- 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.
