Foot & Ankle Flashcards
List the 4 taught foot & ankle points and describe their location
Foot & ankle points
- LR3
Midway between the first and second metatarsals at the level of the midpoint of the second metatarsal. (Analogous to the location of LI 4 in the hand)
- BL60
In the center of the depression located approximately midway between the most prominent aspect of the lateral malleolus and the posterior border of the Achilles tendon, superior to the calcaneus.
- KI3
On the same horizontal line as the most prominent aspect of the medial malleolus in the depression between the medial malleolus and the Achilles tendon.
- GB40
Anterior and inferior to the lateral malleolus, in the sinus tarsi, lateral to the extensor digitorum longus tendon.
