IntroductionThe management of hip fractures has advanced on all aspects from prevention pre-operatively, specialised hip fracture units, early operative intervention and rehabilitation. This is in line with the appropriate recognition over the past years of an important presentation with significant mortality and socioeconomic consequences of ever increasing incidence in an aging population. It is therefore imperative to continue to gather data on the incidence and trends of hip fractures to guide future management planning of this important presentation. MethodsA review of all articles published on the outcome after hip fracture over a twenty year period (1999-2018) was undertaken to determine any changes that had occurred in the demographics and mortality over this period. This article complements and expands upon the findings of a previous article by the authors assessing a four decade period (1959 – 1998) and attempts to present trends and geographical variations over sixty years. ResultsThe mean age of patients sustaining hip fractures continues to be steadily increasing at approximately just over 1 year of age for every 5-year time period. The mean age of patients sustaining hip fractures increased from 73 years (1960s) to 81 years (2000s) to 82 years (2010s). Over the six decade period one-year mortality has reduced from an overall mean of 27% (1960s) to 20% (2010s). The proportion of female hip fractures has decreased from 84% (1960s) to 70% (2010s). There is a decreasing trend in the proportion of intracapsular fractures from 54% (1970s) to 49% (2000s) and 48% (2010s). ConclusionOur study indicates that significant progress has been made with preventative planning, medical management, specialised orthogeriatric units and surgical urgency all playing a role in the improvements in mean age of hip fracture incidence and reduction in mortality rates. While geographical variations do still exist there has been an increase in the study of hip fractures globally with results now being published from more widespread institutions indicating appropriate increased attention and commitment to an ever-increasing presentation.
