This retrospective study investigated the impact of age on fracture occurrence through the comparison of two patient groups, 17-64 and 64+ age groups. Study data covered all fractures treated at a large hospital in eastern Croatia. A total of 15,519 patients with fractures were treated at the trauma department (inpatient and outpatient), with a total of 17,257 fractures presented, 71% managed as outpatients and 29% as inpatients. A total of 11,046 outpatients were treated for 12,187 fractures and a total of 4473 inpatients were treated for 5070 fractures. The group of 17-64-year old males had 5787 fractures, accounting for 34% of all fractures presented. The group of 17-64-year old females had 4094 fractures, accounting for 24% of total fractures. The group of 65+ year-old males had 2659 fractures, accounting for 15% of all fractures presented and the group of 65+ year-old females presented with 4717 fractures, accounting for 27% of all fractures presented. The 'fall in level' was the predominant cause of injury in all patients. The characteristics of osteoporotic bone fractures were evident in the population of 65+ females and to a lesser degree in 65+ males. The 17-64 age group, both males and females, had more fractures considered as high-energy fractures.
