Background:
Surgical complications such as healing problems, in fractures treated using the Arbeitsgemeinschaft für Osteosynthesefragen (AO) technique, present functional and economic challenges to patients and treatment dilemmas for surgeons. Computer-assisted orthopaedic surgery using minimally invasive techniques focused on biological osteosynthesis is a novel direction for fracture treatment.
Method:
We modified the hexapod computer-assisted fracture reduction system by introducing a new reduction strategy, building a new system configuration and upgrading the corresponding software. We then validated the entire system, using a fracture model of bovine femur.
Results:
Precision tests were performed seven times on a bovine femur with a transverse fracture. Residual deviation was 1.23 ± 0.60 mm in axial deflection, 1.04 ± 0.47 mm in translation, 2.34 ± 1.79° in angulation and 2.83 ± 0.96° in rotation.
Conclusion:
Our new reduction system described here is detachable, flexible and more precise in coordinate transformations. The detachable, modular design will allow for more analogous applications in the future. Copyright © 2014 John Wiley & Sons, Ltd.
