To quantify the timing of second contralateral hip fractures and assess their impact on mortality, mobility, and daily activities compared to matched controls with a single fracture, emphasizing the comparative aspect.
Key Findings:
7.6% of eligible patients sustained a second contralateral hip fracture.
The mean interval to the second fracture was 2.2 years, with 40.2% occurring within one year.
Mortality after the second fracture was significantly shorter (1.06 years) compared to controls (1.95 years).
Patients with a second fracture had lower Barthel Index scores (66.7) compared to those with a single fracture (77).
Increased use of walking aids and higher levels of care were observed in patients with second fractures.
Interpretation:
Second contralateral hip fractures are associated with accelerated mortality and functional decline, highlighting the need for improved secondary prevention strategies.
Limitations:
Retrospective design may introduce selection bias, affecting the reliability of the findings.
Limited generalizability due to being a single-center study, which may not reflect broader populations.
Follow-up data reliant on patient or caregiver reporting, which could introduce reporting bias.
Conclusion:
Second contralateral hip fractures significantly impact survival and functional outcomes, necessitating enhanced clinical management and preventive measures to mitigate these effects.
