Anatomic landmarks and marker placement precision

Bone	Landmarks	Description
Calcaneus	1. Posterior calcaneus	Midpoint of posterior surface of calcaneal tuberosity, centred both medial-laterally and vertically.
	2.Anterior calcaneus	Centre of the anterior surface of calcaneus, where calcaneus articulates with cuboid.
	3.Inferior calcaneus	Medial-lateral midline of posterior surface of calcaneal tuberosity, along the inferior border.
	4.Superior calcaneus	Medial-lateral midline of posterior surface of calcaneal tuberosity, along the superior border.
Talus	5. Posterior talus	At medial-lateral midline of the posterior aspect of talus.
	6. Anterior talus	Centre of convex surface of talar head, centred both medial-laterally and vertically.
	7. Medial talus	Dorsal maximum of the medial edge of talar trochlea articular surface.
	8. Lateral talus	Dorsal maximum of the lateral edge of the talar trochlea articular surface.
Cuboid	9. Posterior cuboid	Centre of proximal cuboid articular surface (articulation with calcaneus).
	10. Anterior cuboid	Centre of distal cuboid articular surface (articulation with fourth and fifth metatarsals).
	11. Inferior cuboid	Inferior-lateral edge of the tuberosity of cuboid.
	12. Superior cuboid	Most superior, dorsal “point” of cuboid.
Navicular	13. Medial navicular	Medial aspect of navicular, centred in the anterior-posterior direction.
	14. Lateral navicular	Lateral aspect of navicular; centred in the anterior-poster direction.
	15. Superior navicular	Superior surface of navicular; at the most superior point of its dorsal surface.
