THE EFFECT OF TIBIAL CURVATURE AND FIBULAR LOADING ON THE TIBIA INDEX

Researchers often use the tibia index (TI) to predict leg injury based on measurements taken by an anthropomorphic test device (ATD). An injury criterion based on human tolerance values requires a biofidelic ATD response. This article focuses on the unrealistic curvature of the dummy legs, as well as their lack of a fibular, which can be considered a lack of biofidelity. The problem can be addressed analytically, either by correcting the unbiofidelic ATD measurements before applying them to the TI, or by reformulating the TI to accommodate unbiofidelic ATD measurements. In this study, tibial curvature and fibular load-sharing are quantified through computed tomography imaging and biomechanical testing, and equations are presented to correct ATD measurements to reflect the loading that would be experienced by a human tibia. The human tibial diaphysis generally bows anteriorly and medially, especially at the proximal tibia. The accuracy of the TI may be improved by analytically transforming the tibial moments measured by the dummy legs to their human equivalents.
