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
