English⧼Colon⧽ Figure 1 - Length of the lateral cortex of the first metatarsal. The long axis of the first metatarsal is bisected (line A). A

perpendicular line bisects the tibial sesamoid (line B). The base of the metatarsal is defined (line C). A ruler is placed flush against the cortex and distance B, C measured. Figure 2 - The metatarsus adductus angle measures the position of the lesser tarsus relative to the midfoot. Line D is between the most distal medial point ofthe first cuneiform and the proximal point ofthe navicular. Line E links the distal and proximal lateral points of the cuboid. Line F connects the halfway points of lines D and E. The angle between line F and the second metatarsal bisection gives the metatarsus adductus angle. Figure 3 - The cuneiform angle (C) is

that between a line drawn flush with the distal articular surface of the first cuneiform and the long axis bisection of the first metatarsal. Long axis bisections of the medial and intermediate cuneiforms (lines K and J) provided the intercuneiform angle
