Bone orientation definitions based on anatomical landmarks (right foot)

Bone	First axis	Temporary axis	Second axis	Third axis
Calcaneus	Ycalc = | 1 → 2 |	tcalc = | 3 → 4 |	Xcalc = Ycalc X tcalc	Zcalc = Xcalc X Ycalc
Talus	Ytal = | 5 → 6 |	ttal = | 7 → 8 |	Ztal = ttal X Ytal	Xtal = Ytal X Ztal
Cuboid	Ycub = | 9 → 10 |	tcub = | 11 → 12 |	Xcub = Ycub X tcub	Zcub = Xcub X Ycub
Navicular	Xnav = | 13 → 14 |	tnav = | 13 → 15 |	Ynav = tnav X Xnav	Znav = Xnav X Ynav
