VEGA RODRIGUEZ, N. et al. Epidemiology of hip fracture in Gran Canaria over the five year period of 2007-2011. Rev Osteoporos Metab Miner [online]. 2013, vol.5, n.1, pp.30-35. ISSN 2173-2345.  https://dx.doi.org/10.4321/S1889-836X2013000100005.

Background: Hip fracture is the most serious clinical complication of osteoporosis, due to its raised morbidity and mortality. Method: We have studied the epidemiological and demographic characteristics of all the fragility fractures of the hip occurring in patients of ≥ 50 years of age recorded in Gran Canaria during the 5 year period of 2007-2011 from the admission, coding, emergency and traumatology services of all the hospitals in Gran Canaria, in both the public and private healthcare sectors. Results: A total of 2,222 hip fractures were recorded, of which 1,593 (71.7%) occurred in women and 629 (28.3%) in men. The female/male ratio was 2.53. The average age at which the fractures occurred was 79 ± 9.7 years. Over the 5 years, the total number of fractures (men and women) varied between 402 (in 2007) and 504 (in 2010). The number of fractures increased with age up to the 90s. The annual global incidence was 150 cases/100,000 inhabitants ≥ 50 years: in women 205.4 cases with respect to the population of this sex and age, and in men, 89.1 with respect to the population of men ≥ 50 years. During the winter months 29.7% of the total fractures occurred, 7.5% more than those happening during the summer months (22.2%). Conclusions: During the period 2007-2011 the incidence of hip fracture in Gran Canaria remained more or less stable, in every year being greater in women than in men, and increasing with age up until the 90s. The greatest number of hip fractures occurred during the winter months, with similar numbers in spring, summer or autumn.
