Figures shown here are published frequencies for elective primary hip replacements (total or partial hip replacements excluding replacements for fracture and revision replacements) for the years within the observation period of our study. Where no rates per 100000 population were provided, these were calculated on the basis of absolute frequencies and the population size for the year in question. The corresponding crude rates used in this article for 2011 are 190 cases per 100000 population for Germany and 96 for the USA. Differing demographic structures must be taken into account when comparing crude rates. Percentages of the population aged 65 or older are given for reference. For 2011, this figure is 21% for Germany and 13% for the USA.
The following differences in case definitions must be borne in mind: primary replacements for fracture are not always excluded; some figures are for total hip replacements only
