Differences in femoral fracture localizations in men and women in Switzerland between 1998 and 2021—reversal of the secular trend?
Authors' conclusion
Incidence changes of pertrochanteric fractures and femoral shaft fractures deserve increased attention, especially in men.
Study context
- Population
- Subjects aged 45 years or older living in Switzerland, hospitalized for femoral fractures 1998–2021 (Swiss Federal Office of Statistics medical database)
- Exposure
- Men vs women, by femoral fracture localization, 1998–2021
- Outcome
- Annual number and age-standardized incidence (ASI) trends of femoral neck, pertrochanteric, subtrochanteric and femoral shaft fractures by sex
- Follow-up
- 1998–2021
Methodological detailsnational hospital discharge database, age-standardized incidence trends
- National hospital discharge database
- Age-standardized incidence trends
Main finding
As reported in the abstract
Femoral neck fractures, change in number and ASI over 24 years
| Group | Value | ASI change |
|---|---|---|
| Men | + 45% | 20% decrease |
| Women | - 7% | 37% decrease |
Value
Men+ 45%
Women- 7%
ASI change
Men20% decrease
Women37% decrease
- Significant decrease in ASI, men and women
- P < 0.001 for trend for both
Observational data: associations, not effects.
Further findings
| Outcome | Men | Women |
|---|---|---|
| Pertrochanteric fractures, change in number and ASI trend · Over 24 yearsNumber increased in both sexes | 67% | 45% |
| ASI trend | horizontal (n.s.) | modest significant decrease (p < 0.001) |
| Subtrochanteric fractures, ASI trend · Over 24 yearsNumber increased in both sexes | ||
| ASI trend | modest significant reduction (p = 0.015) | modest significant reduction (p = 0.002) |
| Femoral shaft fractures, change in number and ASI trend · Over 24 years | + 71% | + 100% |
| ASI trend | significant increase (p = 0.001) | significant increase (p < 0.001) |
Age at admission
- Increased for all fracture localizations, more so in men than women and more so for subtrochanteric and shaft than for "typical" hip fractures
