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.

Where is the cuboid bone located in the foot?

• Posterior aspect of the foot

• Anterior aspect of the foot

• Lateral aspect of the foot

• Medial aspect of the foot

What is the primary function of the cuboid bone in relation to the peroneus longus muscle?

• Acts as a stabilizer for the ankle

• Functions as a pulley for the muscle

• Provides cushioning for the foot

• Supports the arch of the foot

Which ligament connects the calcaneus to the cuboid bone?

• Short plantar ligament

• Spring ligament

• Long plantar ligament

• Deltoid ligament

Which arteries supply blood to the cuboid bone?

• Anterior tibial artery

• Fibular artery

• Medial and lateral plantar arteries

• Dorsalis pedis artery

What percentage of the time does the cuboid articulate with the navicular bone?

• 75%

• 50%
