RESULTS:: The parallel locking plates (IMP2) exhibited the highest stiffness in axial load and the highest ultimate strength (p<0.05). No significant differences in sagittal-plane stiffness and in the fatigue properties were seen across the locking plate groups, regardless of orientation. Locked plating constructs performed significantly better in all categories when compared to conventional non-locked plating. Plastic deformation and implant loosening were the main modes of failure following ultimate strength test.
CONCLUSION:: Parallel locking plate configuration showed significantly higher stiffness to axial load and ultimate failure strength when compared to orthogonal locked and non-locked plating. Locked plating configurations performed significantly better than non-locked plating configurations, regardless of orientation. While parallel orientation seems biomechanically superior, translation to the clinical setting may prove difficult when taking surrounding soft tissue and exposure into consideration.
