Cuboid bone

The video tutorial explores the cuboid bone, a short bone in the foot's distal tarsal row. It is the most lateral tarsal bone, located between the calcaneus and the 4th and 5th metatarsals. The cuboid has a square shape, a rough dorsal surface for ligament attachment, and a plantar surface groove for the peroneus longus tendon. It functions as a pulley for this tendon, aiding in foot eversion and plantar flexion. The cuboid articulates with four bones and occasionally with the navicular. It receives blood from the medial and lateral plantar arteries and is innervated by the lateral plantar, sural, and deep fibular nerves.
