Bones Of The Leg Flashcards
Tarsal bones
Talus
Calcaneus
Cuboid
Navicular
Cuneiforms (medial, intermediate, lateral)
Metatarsals
Phalanges
Distal end of the tibia and fibula facts
Lateral malleolus forms, part of the ankle mortars
inferior surface of the tibia is called the tibial pilon or plafond
Medial malleolus will form the rest of the ankle mortars
Ankle mortar is made up of the lateral malleolus, the tibial pilon, and the medial malleolus
What’s the articular surface of the foot with the mortars?
The dome of the talus
Which tarsal bone has a tubercle that forms a trochlea for the peroneal tendons ?
Lateral surface of the calcaneus
Fibula or peroneal trochlea
Fibularis brevis above
Fibularis longus below
Which tarsal bone has the groove for the peroneus longus
Cuboid
Calcaneal tuberosity
Broad attachment for the Achilles tendon
Which bone has a bump or tuberosity for the attachment of tibialis posterior?
Navicular
Groove for flexor hallicus longus
On the calcaneal bone, pass medially and inferiorly to the sustentaculum talus
Shape of talus
Wider anteriorly, than it is posteriorly
So when the ankle is dorsiflexed , the wider part is wedged between the ankle mortice
When the ankle is plantar flexed, a thinner edge of the talus is between the ankle mortice, and that causes a little more joint play
Transverse tarsal joint
Talonavicular and calcaneal cuboid joint
Tarsometatarsal joint
Between the medial, intermediate, and lateral cuneiforms, and the cuboid articulating with the bases of the metatarsals
Plantar calcaneal navicular ligament or spring ligament
Forms the inferior part of the capsule of the Talonavicular joint
Also connects the calcaneus to the navicular because it’s a calcaneal navicular ligament
Groove on the cuboid on the posterior side
For the tendon of peroneus longus
