Although previous studies demonstrate the utility in studying the fibula as a load bearing bone and in assessing load‐bearing patterns related to behavior, the geometric relationships that relate to static mechanical properties are unknown. This study is the first to to document the spatial relationships of the tibia and fibula and the effects these relationships have on cross‐sectional geometric (CSG) properties in a sample of living subjects whose activity patterns are documented (n = 83). Based on prior evidence, tibial strength properties and cross‐sectional shape are expected to relate to the relative anteroposterior location of the fibula, and the distance between the centroids of the two bones. Prelimary results show that fibular location potentially affects CSG properties of both leg bones. Fibular CSG properties relating to strength and rigidity are greater when the centroid of the fibula is more proximal to the centroid of the tibia. Tibiae are stronger in a mediolateral plane when corresponding centroids of fibulae are more posterior. These trends are compared among individuals practicing three sports that habitually utilize different movement patterns. This research fills a gap in current understanding of the role of the fibula in habitual movements associated with different sporting activities.
