A Twenty-Year Study of a Single Institution Examining Age, Gender, and Demographic Differences Between Subcapital and Peritrochanteric Hip Fractures.

Introduction: Limited data indicate demographic differences between peritrochanteric and subcapital hip fractures. This study aimed to document the 20-year hospitalisation rates for hip fractures at a tertiary hospital and compare the prevalence and demographics between the two types of hip fractures.

Materials And Methods: This retrospective study examined the electronic records of patients admitted for hip fractures at our hospital from January 2004 to August 2023, utilising the 10th revision of the International Classification of Diseases codes. We collected demographic data encompassing age, sex, and fracture characteristics.

Results: A total of 5,987 hip fractures (55.4% peritrochanteric and 44.6% subcapital) were included. The number of patients admitted with hip fractures decreased during our country's economic crisis and the COVID-19 pandemic. The incidence of subcapital and peritrochanteric hip fractures over the two decades was comparable (p = 0.232). There were two-and-a-half times more female cases than male cases. Peritrochanteric fractures were more common than subcapital fractures in both sexes, but the ratio between the sexes was comparable (p = 0.532). A significant difference was observed in the mean age (years) of women (80.4 ± 10.1) compared to men (77.0 ± 14.1) (p < 0.001) and between subcapital (77.8 ± 11.9) and peritrochanteric hip fractures (80.7 ± 10.9) (p < 0.001). The mean age of women with peritrochanteric fractures (81.9 ± 8.9) was statistically different from those with subcapital hip fractures (78.4 ± 11.0) (p < 0.001). This difference was not significant for men (p = 0.114). Individuals over 75 years old were involved in 76.8% of all cases, with the majority being women (57.5%). There was a significant increase in the ratio of female to male cases over 75 years (p < 0.001).

Conclusions: Our research indicated that women are more likely to develop hip fractures than men. Additionally, peritrochanteric fractures are more common than subcapital fractures. The risk of developing hip fractures increases with age, particularly after 75. Furthermore, hip fractures in women occur significantly later than in men, and the same applies to peritrochanteric compared to subcapital fractures. There may be demographic disparities between peritrochanteric and subcapital hip fractures.
