Tibial nerve (L4,L5,S1)
23
Q

What surfaces are involved in the ankle joint?

A

Distal end of tibia and fibula

Trochlea of Talus

24
Q

How many muscles are in the posterior compartment of the leg?

A

7 muscles

  • 3 superficial
  • 4 deep
25
Q

What are the attachments of the tibialis posterior muscle?

A

Posterior surface of the tibia and fibula, interosseous membrane
Inserts into the tuberosity of navicular, cuneiforms, cuboid, sustentaculum tail of the calcaeneus, and the base of the 2nd, 3rd and 4th metatarsals

26
Q

What nerve gives cutaneous innervation to the pink patch?

A

Posterior cutaneous nerve of the thigh

27
Q

What is the action of the popliteus?

A

Unlocks the knee joint by laterally rotating the femur on fixed tibia

28
Q

What is the action of flexor digitorum longus?

A

Flexes the lateral 4 digits

Weak plantarflexion of the ankle

29
Q

What are the 3 parts of the lateral collateral ligaments and where they insert?

A

Anterior talofibular - inserts into neck of talus
Posterior talofibular - inserts into lateral tubercle of talus
Calcaneofibular - inserts lateral surface of the calcaneous

30
Q

What nerve gives cutaneous innervation to the light blue section?

A

Lateral sural cutaneous nerve

31
Q

Describe the route of the posterior tibial artery and its branches?

A

Posterior tibial artery is a terminal branch of the popliteal artery. Runs between the heads of gastrocneumius and deep to the soleous on the surfaces of TP and FDL

  • Gives the fibular artery as a branch
  • Terminates as the medial and lateral plantar arteries in the foot
32
Q

What is the origin of plantaris?

A

Lateral supracondylar line of the femur

proximal to the lateral head of gastrocneumius

33
Q

What tarsal bone does the tibialis posterior NOT attach to?

A

Talus

34
Q

What is the medial to lateral arrangement of the tendons of the deep posterior compartment at the ankle joint?

A

Tibialis posterior, flexor Digitorum longus, and flexor Hallucis longus

(Tom, Dick and Harry)

35
Q

What is the function of plantaris?

A

Assists with plantarflexion of the ankle

36
Q

What is this muscle and its innervation?

A 
Flexor hallucis longus

37
Q

What does this image show?

A

38
Q

What muscle is being highlighted and what is its innervation?

A

39
Q

Describe the Tibial nerves route

A
  • Passes between the heads of gastrocneumius and deep to tendinous arch of soleus, with the posterior tibial artery
  • Passes between the FHL and FDL at the ankle joint
  • Gives terminal branches to supply the sole of the foot - the medial and lateral plantar nerves
