Location

On the highest point of the dorsum of the foot, between the ten-

dons of the extensor hallucis longus and the extensor digitorum

longus, directly lateral to the point where the dorsalis pedis artery

may be palpated. The point is bordered proximally by the 2nd and

3rd metatarsal bones and distally by the 2nd and 3rd cuneiform

bones. Alternative location:Sometimes, this point may be

located lateral to the medial portion of the extensor digitorum

longus tendon (joining the 2nd toe).

How to find

With the palpating finger, glide from ➞ST-43(in the depression

between the base of the 2nd and 3rd metatarsal bones) proximally

towards ➞ST-41(in the depression between the tendons of

extensor digitorum longus and hallucis longus). Locate ST-42at

the highest point of the dorsum of the foot, in a depression lateral

to the pulse. In most cases, ST-42is located lateral to the tendon

of the extensor hallucis longus, which becomes more distinct by

extending the big toe.
