Epidemiology and social costs of hip fracture.

Hip fracture is an important and debilitating condition in older people, particularly in women. The epidemiological data varies between countries, but it is globally estimated that hip fractures will affect around 18% of women and 6% of men. Although the age-standardised incidence is gradually falling in many countries, this is far outweighed by the ageing of the population. Thus, the global number of hip fractures is expected to increase from 1.26 million in 1990 to 4.5 million by the year 2050. The direct costs associated with this condition are enormous since it requires a long period of hospitalisation and subsequent rehabilitation. Furthermore, hip fracture is associated with the development of other negative consequences, such as disability, depression, and cardiovascular diseases, with additional costs for society. In this review, we show the most recent epidemiological data regarding hip fracture, indicating the well-known risk factors and conditions that seem relevant for determining this condition. A specific part is dedicated to the social costs due to hip fracture. Although the costs of hip fracture are probably comparable to other common diseases with a high hospitalisation rate (e.g. cardiovascular disease), the other social costs (due to onset of new co-morbidities, sarcopenia, poor quality of life, disability and mortality) are probably greater.
