Falls in the elderly constitute one of the main public health problems, both due to their prevalence and consequences. One of the most serious is the fracture of the femur. The annual prevalence of falls in the over 65 population ranges between 28% and 35%, and these falls are frequently repeated 1 . The factors responsible for a fall are divided into intrinsic (related to the patients themselves) and extrinsic (derived from the activity or the environment), the cause being multifactorial in most cases 1 . When assessing the intrinsic factors of a fall, we must take into account the physiological disorders related to age (including the presence of nutritional alterations, sarcopenia and frailty), acute and chronic diseases and the prescription of certain drugs 1 . For this reason, when faced with a fall, it is essential to have a comprehensive approach to the adult through a global geriatric assessment that includes a complete assessment of gait and balance.We mention frailty, which ,may be erroneously considered another word for disability and comorbidity. However, frailty is a potentially reversible situation in which there is a progressive decrease in the physiological reserve capacity and in the adaptation capacity of the body's homeostasis (homeostenosis) that occurs especially with non-physiological aging. Frailty, as a clinical entity, is influenced by (individual) genetic factors and is accelerated by acute and chronic diseases, toxic habits, disuse, and social and care conditioning factors. There are currently two fundamental approaches to frailty: a functional and restrictive one, proposed from the Linda Fried phenotype, according to which frailty would be a state prior to disability but different from it, assessed by five components (weight loss, tiredness, weakness, psychomotor slowdown and hypoactivity). There is another, broader but less defined conception in terms of a less clear differentiation of frailty and disability, and in which frailty would be attributed to an accumulation of deficits (Rockwood cumulative indices of frailty).Between these two positions, there is an important multitude of intermediate options 2 .By the same token, there may be an interaction, and overlap, between the presence of frailty and sarcopenia. With age, starting at thirty years old, there is a progressive
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
