Os cuboideum

How to find it
Find the tuberosity of the fifth metatarsal and move one to two centimetres proximally along the lateral border. That bone lies between that tuberosity and the calcaneus.
What you use it for
On the plantar side the fibularis longus tendon runs through a groove in this bone. Cuboid subluxation is a known cause of lateral foot pain persisting after an inversion injury.
