Foot And The Posterior Leg Flashcards
What are the 3 tibiofibular ligaments in the foot
The anterior tibiofibular ligament
The posterior tibiofibular ligament
Interosseous membrane
What makes up the hind foot
Talus
Calcaneus
What makes up the midfoot
The navicular (anterior to talus)
Cuneiforms
Cuboid (lateral, next to little toe)
What makes up the forefoot
The metatarsals
The phalanges
Why is the medial aspect of the foot more stable then the lateral
Medial would have 4 ligaments
Lateral would only have 3 ligaments
What is the difference between the anterior and the posterior aspects of the talus trochlea
The posterior would be narrower then the anterior
What happens when you dorsi flex the foot
The anterior aspect of the talus trochlea would move posteriorly
The tibia and the fibular would move apart slightly
The tibiofibular ligaments would tighten
In what position would the foot be more unstable
When plantar flexed
What is the sustentaculum tail
Area on the medial aspect of the calcaneus
What are the lateral aspects of the foot (fibular)
Anterior talofibular ligament
Posterior talofibular ligament
Calcaneofibular ligament
What are the ligaments on the medial side of the foot
Medial mallolus to the talus
Tibiocalcaneal
Tibionavicular
Anterior tibiotalar
What are the major ligaments of the foot
The spring ligament (goes from the sustentaculum to the navicular)
The long plantar ligament (calcaneus to the 4 metatarsals)
Short plantar ligament (Calcaneus to the cuboid)
What are the muscles in the anterior part of the leg
The tibialis anterior
The extensors digitorium longus
Extensor hallicus longus
Fibularis teritus
What are the artery’s in the anterior leg
(From the femoral and the popliteal artery)
Anterior tibial artery
Dorsalis pedis artery of the foot
What nerve innovates the anterior compartment of the leg
The deep fibular nerve
What are the muscles in the lateral aspect of the leg
The fibularis brevis and longus
What nerve supplies the lateral aspect of the foot
The superficial fibular nerve
What would the extensor retinaculum prevent
Bowstringing of the foot
What is the function of the tibialis anterior
Inverts
Dorsi flex
What is the function of the extensor digitorium longus and hallicus longus
Extends and dorsi flexes
What is the function of the fibularis teritus
Eversion
Dorsi flex
What is the function of the lateral aspect of the food
Eversion
plantar flexion
What would happen if there was a lesion on the deep fibular nerve
Would have a footdrop
What nerve would the deep fibular nerve come from
The common fibular nerve
Where can the anterior tibial artery be palpated
Lateral to the extensor hallicus longus
Where can the posterior tibial artery be palpated
Half way between the Achilles’ tendon and the medial malleolus
Where can the femoral artery be palapated
Half way between the ASIS and the pubic symphysis
Where can the dorsalis pedis artery be palpated
Lateral to the extensor hallucis longus tendon on the dorsal of the foot
What are muscles of the foot
Extensor hallucis brevis (extensor of the big toes)
Extensor digitorium brevis (extends the 4 toes)
What do the tibial nerve and the posterior tibial artery become in the foot
The medial and lateral plantar nerves and arterys
What does the medial plantar nerves and artery’s control
Medial 3 and a half digits
What do the lateral plantar nerves and artery’s control
The lateral 1 and a half artery’s
What muscle is above the plantar neurovascular vessels
Abductor hallucis brevis
What is the purpose of the arches in the foot
Shock absorber
Spring board
What nerve would supply the lateral aspect of the foot
The aural nerve
What nerve would supply the medial aspect of the foot
The saphenous nerve
What nerve would supply the dorsal of the foot
The superficial fibular nerve
Where would the sural nerve pass
By the lateral malleolus of the foot
