How to find
When palpating along the lateral aspect of the foot on the level
of the border of the ‘red and white’ skin, a bony structure can be
felt approximately at the midpoint of the foot. This is the
tuberosity of the 5th metatarsal bone (➞3.6.2). BL-64is located
directly distal to it (towards the toes), at the junction between the
base and the shaft of the 5th metatarsal bone.
➞BL-63is located proximal to the tuberosity of the 5th metatarsal
bone, in a depression between the calcaneus and cuboid bone
(or between the tuberosity and the cuboid bone). ➞SP-4is
located in a comparable position on the medial aspect of the
foot, in a depression distal to the base of the 1st metatarsal bone.
