The aim was to study correlation between geometric measurements of proximal femur and development of femoral neck fracture in patients with osteoporosis.
Materials and Methods. There were 2 groups of patients with osteoporosis of the same age: 1st group - 64 patients (17 men and 47 women) with femoral neck fracture; 2nd group - 101 patients (17 men, 84 women) without fracture.
BMD was evaluated in Ward triangle and great trochanter using LUNAR DPX-L. The femoral neck axis length (fnal) and neck width (FNW) were detected by manual regime using scan image.
Results. In patients of both sexes with femoral neck fracture BMD was higher compared with patients of 2nd group. In women those differences were significant: in femoral neck 0,769+0,04 vs 0,657+0,3 (p<0,01); Ward triangle 0,599+0,04 vs 0,492+0,03 (p<0,01); great trochanter - 0,684+0,03 vs 0,598+0,03 (p<0,01), respectively. The FNAL was greater in women with fracture than in women without fracture (90,5+1,37 vs 87,7+1,19 mm, p<0,001). In men significant differences were detected in FNW.
In group with fracture FNW was 33,6+0,79 vs 35,9+0,43 (p<0,01) in group without fractures.
Conclusion. The data obtained testified that in women risk factor for femoral neck fracture might be the length of femoral neck and in men the width of femoral neck.
