FIGURE 32.4 Annual numbers of hip fractures, unadjusted hip fracture rates, and age-standardized hip fracture rates per 100,000 person-years in Canada. Although the fracture rate had declined, the numbers of hip fractures has increased because of the expansion in the elderly population. Source: Leslie et al. (2009), with permission [31].

Grade 0, normal (no radiographic evidence of vertebral demineralization or fracture). Grades 1–3, progressively severe vertebral demineralization and fracture. Source: Ross et al.

Values are mean ± 1 standard deviation (SD) *p < 0.001. Values in men are shown by the open bars; values in women are shown by shaded bars. Source: Gilsanz et al. (1994), with permission [575].
