Week 4: Ankle and Foot Flashcards
What is the name of the membrane between tibia and fibula?
Interosseous membrane (IOM)
Name and function of ankle joint?
Talocrural joint is a hinge synovial joint. Promotes stability and mobility
What position is the ankle joint the most stable?
Dorsiflexion
What’s the most common ankle-inversion injury?
Torn anterior taliofibular ligament?
Gastocnemius Func, Attach and NS
Proximal:
Lateral head: lateral aspect of lateral condyle of the femur
Medial head:popliteal surface of femur, superior to medial condyle
Distal: calcaneal tendon - posterior surface of calcaneus
Action: Knee flexion and ankle plantarflexion
NS: Tibial nerve
Soleus Func, Attach and NS
P.A: Posterior aspect of head of fibula, soleal line and middle 1/3 of medial border of tibia
D.A: Calcaneal tendon - posterior surface of calcaneus
Action: ankle planarflexion
NS: Tibial nerve
Plantaris Func, Attach and NS
P.A: Lateral supracondylar line of femur
D.A: Calcaneal tendon - posterior surface of calcaneus
Action: weak plantarflexor
NS: Tibial nerve
Identify ABCD, How to remembeer BCD?
A: Popliteus
B: Flexor Digitorium Longus
C:Tibialis posterior
D: Flexor Hallucis Longus
Popliteus Func, Attach and NS
P.A: lateral surface of lateral condyles of femur
D.A: posterior suface of tibia, superior to soleal line
Action: “unlocks knee”
NS: Tibial nerve
Tibialis F, A and NS?
P.A: Interosseous membrane (IOM), posterior surface of tibia infrior to soleal line and posterior surface of fibular
D.A: tuberosity of navicular and across the plantar surface of the foot to the 2nd to 4th metatarsels
Action: Ankle plantarflexion and inversion
NS: Tibial Nerve
Flexor Digitorum Longus F, A and NS?
P.A: Medial part of posterior surface of tibia, inferior to soleal line
D.A: Plantar surface of base of distal phalanges of lateral 4 digits
Action: Flexion of lateral 4 digits and ankle plantarflexion
NS: Tibial nerve
Flexor Hallucis Longus F, A and NS
P.A: inferior 2/3 of posterior surface of fibula and inferior IOM
D.A: plantar surface of base of distal phalanx of hallux
Action: Flexion of hallux, weak ankle plantarflexion
NS: Tibial nerve
What’s A, B, C and D
A: Tibialis anterior
B: Extensor Digitorium longus
C: Extensor Hallucis longus
D: Fibularis tertius
Tibialis Anterior F, A and NS
P.A: lateral condyle and superior half of lateral surface of tibia and interosseous membrane
D.A: plantar surface of medial cuneiform and base of 1st metatarsal
Action: Ankle dorsiflexion and inversion
NS: Deep fibular nerve
Extensor Hallucis Longus
