“…This agrees with local studies [20,21] but at variance with western studies which women are twice at risk due to post menopausal osteoporosis and longer lifespan [18,19] The age range was 28 to 90years with mean age of 63.8± 15years is in keeping with results obtained in local studies [ 20,21] ,however, the mean age of 72 -77years reported in western studies [22,23] reflect the higher life expectancy of their population. The predominant mechanism of injury was trivial falls in 26 (54.2 %) patients.…”

“…In white women, but not in African-American women or men, the ratio of TR to FN hip fractures increases with age, and in both genders and all ethnicities, the TR fractures are more common in frailer individuals [11,14,[16][17][18]20,22,28].…”

Fragility fractures at the trochanter (TR) and the femoral neck (FN) have distinct etiologies, but the underlying age-related structural changes at these proximal femoral sub-regions are poorly understood. 28 young (41 ± 3 years) and 124 elderly (74 ± 3 years) healthy Caucasian women underwent volumetric quantitative computed tomography at the hip. Integral (i), cortical (c) and trabecular (t) bone mineral density and content (BMD, BMC) were measured. Geometric parameters included cross sectional area (CSA), and volumes of the integral, cortical and trabecular regions (VOL). Structural measures included indices of compressive (Compstr) and bending (BSI) strength. After adjusting for height and weight, an F-test was used to compare the TR and the FN mean values between young and elderly and to test for interaction to compare logarithmic difference of young and elderly (log(Young)-log(Elderly), Y/E d ) between the FN and the TR in an ANOCOVA model. All BMC, iBMD and tBMD values were significantly lower in elderly than in young women, with the largest Y/E d in the FN tBMC and tBMD (P < 0.0011 and P < 0.0001). cBMD in young and elderly groups was not significantly different at the TR while at the FN it was greater (P = 0.0075) in elderly than young women, showing significant Y/E d (P = 0.0003) dependence on skeletal site. Elderly women had significantly larger iVOL and CSA values (0.0001 < P < 0.0051), except for the FN iVOL. cVOL values were smaller in elderly than young women (P < 0.0001). Y/E d in bone geometry differed by sub-region only for cVOL measures (P = 0.0267). Despite larger CSA and iVOL measures in elderly, the younger women had greater Compstr (P < 0.0001) and BSI (P = 0.0051). Thus, although both the TR and the FN appear to increase in size with age, this enlargement is insufficient to protect against loss of bone strength.

“…Furthermore, bone fractures impose a substantial economic burden to health services and to society (Johnell, 1997). Hip fractures contribute the most to this burden, mainly in terms of severity, functional dependence, social and economic cost and fatality (Kannus et al, 1996;Cummings and Melton, 2002).…”

Diet and hip fractures among elderly Europeans in the EPIC cohort

et al. 2010

Background/Objectives: Evidence on the role of diet during adulthood and beyond on fracture occurrence is limited. We investigated diet and hip fracture incidence in a population of elderly Europeans, participants in the European Prospective Investigation into Cancer and nutrition study. Subjects/Methods: 29 122 volunteers (10 538 men, 18 584 women) aged 60 years and above (mean age: 64.3) from five countries were followed up for a median of 8 years and 275 incident hip fractures (222 women and 53 men) were recorded. Diet was assessed at baseline through validated dietary questionnaires. Data were analyzed through Cox proportional-hazards regression with adjustment for potential confounders. Results: No food group or nutrient was significantly associated with hip fracture occurrence. There were suggestive inverse associations, however, with vegetable consumption (hazard ratio (HR) per increasing sex-specific quintile: 0.93, 95% confidence interval (CI): 0.85-1.01), fish consumption (HR per increasing sex-specific quintile: 0.93, 95% CI: 0.85-1.02) and polyunsaturated lipid intake (HR per increasing sex-specific quintile: 0.92, 95% CI: 0.82-1.02), whereas saturated lipid intake was positively associated with hip fracture risk (HR per increasing sex-specific quintile: 1.13, 95% CI: 0.99-1.29). Consumption of dairy products did not appear to influence the risk (HR per increasing sex-specific quintile: 1.02, 95% CI: 0.93-1.12). Conclusions: In a prospective study of the elderly, diet, including consumption of dairy products, alcohol and vitamin D, did not appear to play a major role in hip fracture incidence. There is however, weak and statistically non-significant evidence that vegetable and fish consumption and intake of polyunsaturated lipids may have a beneficial, whereas saturated lipid intake a detrimental effect.
