“…However, in our study only NL was significantly correlated with the occurrence of hip fractures while the difference in NW between fractures subjects and controls was not significant. This finding was concordant with other reports [26,33,36].…”

To investigate the relationship between proximal femoral geometry and the occurrence of hip fracture, we compared the geometry of contralateral normal hips of 120 elderly Chinese women with hip fractures, including 63 femoral neck fractures (group A) and 57 intertrochanteric fractures (group B) due to minor trauma, with that of 72 normal elderly Chinese women (group C). The mean ages for group A, B and C subjects were 77.3, 79.7 and 72.9 years, respectively. The femoral neck length (NL), neck width (NW), diameter of femoral head, femoral shaft width just below the lesser trochanter, and neck-shaft angle (theta;) were measured on the anteroposterior plain pelvic radiographs. The mean +/- SD of NL for group A was 50.4 +/- 3.3 mm; for group B, 50.6 +/- 3.1 mm; and for group C, 48.8 +/- 3.6 mm. Statistical analysis by ANOCOVA and regression showed that only NL of women with hip fractures was significantly longer than controls after correction for age, body height and weight (p <0.01). However, the difference in NL between group A and group B was not significant. By linear regression, the probability of fracture increased only with older age (p <0.001), longer NL (p <0.005) and lighter body weight (p <0.05). By logistic regression, each standard deviation increase in NL increased the risk of hip fracture (age-adjusted odds ratio 1.84; 95% CI, 1.11-3.06). The results confirm the relationship between proximal femoral geometry and the occurrence of hip fracture in elderly Chinese women in Taiwan.

“…Previous studies have suggested that the specific site of femoral fractures may be related to patient-level variables, such as nutrition [25] and morphology of the femur [26,27], including hip axis length and cortical thickness. A review article by Mautalen and colleagues [26] showed that women with trochanteric hip fractures may be older, thinner, and shorter, have lower bone mass at the proximal femur and spine, and have a more severe alteration of trabecular bone properties than women with femoral neck hip fractures [26].…”

“…The association of geometric characteristics of the upper femoral end, with a possible risk for hip frac-ture, was studied by several authors (Hagberg and Nilsson 1977, Dretakis and Christodoulou 1983, Ferris et al 1989, Faulkner et al 1993, Cummings et al 1994. Faulkner et al (1993) found that a longer than average hip axis was an independent risk factor in hip fracture and this was present in both cervical and trochanteric fractures.…”
