Inertial axes reflecting bone shape. Surface maps of the 7 tarsal and 5 metatarsal bones, with a minimum bounding volume surrounding calcaneus representing the direction vectors for the principal inertial axis (red), second inertial axis (green), and third inertial axis (blue). (A) Lateral view of an exemplar foot, showing that the principal inertial axis reasonably approximates calcaneal pitch; (B) Posterior view of the foot, showing that the second and third inertial axes fail to align with clinically-relevant axes representing the local medial-lateral and inferior-superior axes of calcaneus.
