Os cuboideum

The video tutorial provides an in-depth look at the OS Cuboideum, a small bone located in the distal row of the tarsal bones. It covers the bone's articulations with surrounding bones, its role in foot movement such as pronation and plantar flexion, and its importance in the clinical metatarsus. The tutorial also details the vascular and nerve supply to the OS Cuboideum, highlighting its significance in foot anatomy.

• Supination

• Pronation

• Dorsiflexion

Which artery supplies blood to the OS Cuboideum?

• Anterior tibial artery
