Summary
Dual fixation, particularly intramedullary nail/plate combinations, improved return to baseline ambulation for interprosthetic femur fractures (IFFs). Higher comorbidity burden increased mortality risk in these patients.
Area of Science:
- Orthopedic Surgery
- Trauma Surgery
- Biomedical Engineering
Background:
- Interprosthetic femur fractures (IFFs) present complex treatment challenges.
- Identifying optimal fixation strategies is crucial for improving patient outcomes.
Purpose of the Study:
- To identify current practices for treating interprosthetic femur fractures (IFFs).
- To determine factors influencing positive patient outcomes, including union rates, complications, and ambulation status.
Main Methods:
- Retrospective cohort study involving 139 patients aged 50-90 years across 15 US trauma centers.
- Analysis of fixation methods (lateral plate, nail-plate, dual plates) and their association with outcomes.
- Statistical analysis including Chi-square tests, Fisher's exact tests, and ANOVA.
Main Results:
- Lateral plating was the most common fixation (85%).
- Dual plate fixation, especially nail-plate combinations, showed faster time to full weight-bearing and higher rates of return to baseline ambulation.
- Overall mortality was 13%, associated with comorbidities.
Conclusions:
- Spanning lateral plates are frequently used for IFFs.
- Dual fixation techniques, particularly intramedullary nail/plate, enhance functional recovery.
- Comorbidity burden is a significant predictor of mortality in IFF patients.
