Advanced Bones of the Foot Quiz

Q1. Which foot bone transmits body weight from the tibia to both the calcaneus and the forefoot?

• Fifth metatarsal
• Talus
• Cuboid
• Navicular

Q2. Why is the talus unusual among major bones of the foot?

• It does not articulate with the tibia
• It is the only foot bone with a muscle belly
• It contains no articular surfaces
• It has extensive articular cartilage and no direct muscular attachments

Q3. Which bony arrangement is especially important for stability of the Lisfranc region?

• The recessed second metatarsal base between the cuneiforms
• The calcaneal tuberosity between the cuneiforms
• The talar trochlea between the metatarsals
• The fifth metatarsal head between the phalanges

Q4. A fracture at the tuberosity of the fifth metatarsal can occur through traction from which tendon?

• Tibialis posterior tendon
• Tibialis anterior tendon
• Flexor hallucis longus tendon
• Fibularis brevis tendon

Q5. Why is a fracture through the proximal fifth metatarsal clinically distinguished by its exact location?

• The fifth metatarsal has no vascular supply
• All fifth metatarsal fractures have identical blood supply
• Only distal phalangeal fractures can fail to unite
• Different proximal fracture zones have different healing characteristics

Q6. Which bones form the principal osseous framework of the medial longitudinal arch?

• Five metatarsals without any tarsals
• Calcaneus and phalanges only
• Calcaneus, talus, navicular, cuneiforms, and medial three metatarsals
• Talus, cuboid, and lateral two metatarsals only

Q7. Which bones contribute most directly to the lateral longitudinal arch?

• Talus, navicular, and first metatarsal only
• Tibia, fibula, and talus only
• Calcaneus, cuboid, and fourth and fifth metatarsals
• Three cuneiforms and great toe phalanges

Q8. Why is the head of the talus important in the medial longitudinal arch?

• It occupies a key weight-bearing position near the summit of the arch
• It articulates directly with all five metatarsals
• It is embedded in the Achilles tendon
• It forms the heel contact point

Q9. Which bony landmark is commonly used clinically to assess the medial midfoot because it is readily palpable?

• Intermediate cuneiform dorsal surface
• Fourth metatarsal head
• Talar trochlea
• Navicular tuberosity

Q10. Which statement best integrates the organization of the bones of the foot?

• All foot bones are fused in the adult
• The foot contains only tarsals and phalanges
• The 26 bones form an articulated framework for weight bearing, arches, balance, and propulsion
• The metatarsals form the ankle mortise
