Insights
Osteoporotic sequential bilateral hip fractures (SBHF) occurred in 8.2% of patients over 60, with higher incidence in femoral neck fractures. Hypertension and female sex were identified as risk factors for SBHF.
Area of Science:
- Orthopedic Surgery
- Geriatric Medicine
- Public Health
Background:
- Osteoporotic hip fractures are a significant health concern in elderly populations.
- Limited data exists on sequential bilateral hip fractures (SBHF) in Korea.
- Understanding the incidence and risk factors for SBHF is crucial for prevention strategies.
Purpose of the Study:
- To determine the incidence and clinical presentation of osteoporotic sequential bilateral hip fractures (SBHF).
- To identify correlations between initial fracture type, risk factors, and SBHF.
- To compare bone mineral density (BMD) before and after sequential hip fractures.
Main Methods:
- Retrospective review of 507 patients aged over 60 with osteoporotic hip fractures (2009-2015).
- Analysis of fracture types (femoral neck vs. intertrochanteric) and occurrence of SBHF.
- Assessment of risk factors including comorbidities (hypertension) and sex, with BMD measurements.
Main Results:
- Cumulative incidence of SBHF was 8.2% (42 patients).
- Higher incidence of SBHF in femoral neck fractures (29 patients) compared to intertrochanteric fractures (13 patients).
- Hypertension and female sex identified as risk factors; significant correlation found between initial fracture type and SBHF.
Conclusions:
- The incidence and presentation of SBHF in this Korean cohort align with international findings.
- Identifying risk factors like hypertension and female sex can inform targeted prevention programs.
- Further research may refine strategies to mitigate the risk of secondary hip fractures.
Purpose:
To evaluate the incidence and presentation of osteoporotic sequential bilateral hip fractures (SBHF) in Center for Joint Disease, Chonnam National University Hwasun Hospital as there are limited studies with variable results reported in Korea.
Materials And Methods:
Records of 507 patients aged >60 years old presenting with osteoporotic hip fractures between 2009 and 2015 were retrospectively reviewed to document the occurrence and presentation of sequential hip fractures; mean post-treatment follow-up was 48 months. Additionally, any correlations between sequential fractures and initial fracture and risk factors were assessed. Bone mineral density (BMD) was measured before and after sequential hip fracture for comparison.
Results:
There were 246 femoral neck (Group A) and 261 intertrochanteric (Group B) fractures. The cumulative incidence of SBHF was 8.2% (42 patients total; 29 in Group A and 13 in Group B). Average interval of SBHF for Group A and Group B were 37.4 months and 29.9 months, respectively. There was significant correlation between the initial fracture type and sequential fractures, particularly the trochanteric and subgroup of those with neck fractures. Hypertension as a co-morbidity and female sex have been identified as risk factors for SBHF. No significant findings were noted regarding BMD and risk factors in both groups.
Conclusion:
The clinical presentations of SBHF noted here concur with other worldwide studies and may guide efforts to develop relevant programs to prevent SBHF.
