Primary Institution: University of Virginia Health System
Hypothesis
The biomechanical properties are similar.
Conclusion
Plate constructs are superior in showing less displacement at fixed loads and greater loads at fixed displacements.
Supporting Evidence
- Plate constructs showed less displacement at fixed loads.
- Plate constructs required greater loads at fixed displacements.
- The study used a robust sample size of matched clavicle pairs.
Takeaway
This study looked at how well two types of devices hold broken clavicles together, finding that one type works better than the other.
Methodology
Eight sets of matched clavicles were tested using a four-point bending method with cyclic loading.
Limitations
The study used cadaveric specimens, which may not fully represent living patients.
Participant Demographics
5 male and 3 female specimens aged 37 to 68 years.
