Abstract

Purpose

To analyze difference in bone mineral density (BMD) between intertrochanteric fracture and control group and to explore the predictive value of BMD for intertrochanteric fracture.

Materials and Methods

57 patients who were over 60-year-old with intertrochanteric fracture were examined. For control group, 110 patients who did not have any fracture were selected. Dual energy X-ray absorptiometry was studied at 1, 2, 3, 4 lumbar vertebrae, femoral neck, trochanter and Ward's triangle. BMD was compared at each site between two groups statistically.

Results

Fracture group consisted of 16 male, 41 female and was average 70.8 year old. Control group consisted of 21 male, 89 female and was average 68.1 year old. There was no differences in sex and age between two groups (p>0.05). BMD of L1, L2 and mean lumbar area were significantly less in fracture group than control group (p<0.05). There was no difference between two groups in BMD of another sites (p>0.05).

Conclusion

BMD of L1, L2 and mean lumbar area in fracture group had lower value significantly, but had no differences between two groups at another sites. BMD of L1, L2 and mean lumbar area might be used as the most sensitive predictive indicator for risk of osteoporotic fractures including intertrochanteric fracture in elderly patient.
