(
Figs 3.114, 3.115)

When palpating along the medial aspect of the midfoot in a proxi-

mal direction, the proximal end (base) of the 1st metatarsal bone

forms the first distinct prominence. 
SP-4is located distal to this

bony orientation point, at the junction of the shaft and the base.

Navicular tuberosity (
Fig. 3.115)

When palpating along the medial side of the foot, past 
SP-4

and the base of the 1st metatarsal bone, a further bony structure can

be clearly felt. This is the navicular tuberosity, where 
KID-2

is located.
