27
Q

What are the relative positions of the tendons that pass posterior to the medial malleous?

A

Flexor Digitorum Longus
Flexor Hallucis Longus

28
Q

What two nerves foes the tibial nerve branch into after it passes posterior to the medial malleolus?

A

Medial and lateral plantar nerves

29
Q

Describe the branching of the medial plantar nerve

A

Medial plantar nerve gives rise to the common plantar digital nerves that innervate digits 1-3, and those give rise to the proper plantar digital nerves.

30
Q

Describe the branching of the lateral plantar nerve.

A

Lateral plantar nerve gives rise to a superficial branch that innervates the 4th and 5th digit. The superficial branch gives rise to a common plantar digital nerve.

Lateral plantar nerve also gives rise to a deep branch that goes to the deeper layers of foot.

31
Q

Where would you take the medial malleolar pulse?

A

Posterior to the medial malleolus or posterior to Flexor Hallucis longus

32
Q

Where would you take the dorsalis pedis pulse?

A

Lateral to extensor hallucis longus. or just over where talus and navicular bones articulate.

A

Plantar flexion
Dorsiflexion
Inversion
Eversion

34
Q

What are the attachments of the talocrural fibrous capsule?

A

From the borders of the articular surfaces of tibia and malleoli to the margins of the trochlear surface of the talus

35
Q

What are the attachments of the medial collateral (deltoid) ligament?

A

From the medial malleolus to the talus, navicular and sustentaculum tali of the calcaneous.

36
Q

What is the function of the medial collateral (deltoid) ligament?

A
