Static and Dynamic Differences in Fixation Stability between a Spacer Plate and a Small Stature Plate Fixator Used for High Tibial Osteotomies: A Biomechanical Bone Composite Study
Table 2
Used failure types and their defining criteria.
Failure type
Criteria
1
Visible yielding and dislocation/tilt of the tibia plateau of more than 2 mm. This criterion can only be checked in the unloaded condition and addresses the unwanted loss of correction after surgery.
2
Visible collapse of lateral cortex. Small hairline cracks are not considered as failure.
3
Maximal displacement range of more than 0.5 mm within one hysteresis loop in the case of cyclic testing only.
