Q

Explain the movements of eversion. Summarize the muscles responsible for these movements, their innervation.

A

lateral side of the foot comes up

Innervation: superficial fibular nerve (fibularis longus, brevis) deep fibular nerve (fibularis tertius)

Lateral Compartment: Fibularis Longus (goes medial to the foot; helps pull the foot down) Fibularis Brevis (goes around the lateral side of the foot, helps with pulling the foot up)

Q

The superficial muscles of the posterior compartment of the leg attaches to what?

A

Gastrocnemius and Soleus attaches at the calcaneus (makes up the achilles/calcaneal tendon)

Plantaris can either join the achilles tendon or it can go directly to the Calcaneus.

Q

What is the articulation of the subtalar joint?

A

Calcaneus and the talus

17
Q

What is the function the the subtalar joint?

A

gliding and rotation, which are involved in inversion and eversion of the foot

18
Q

What are the ligaments of the subtalar joints?

A

Lateral, medial, posterior and interosseous talocalcaneal ligaments

19
Q

Subtalar joints are stabilized by:

A

medial and lateral ligaments

20
Q

Which ligament of the subtalar joint helps prevents inversion injuries/sprains?`

A

Calcaneofibular Ligament

21
Q

What are sprains of the ankle?

A

Ligament stretched so much that it tears. This happens when you invert and dorsiflex the foot.

22
Q

What ligaments are most likely to be torn during an inversion sprain?

A

The anterior talofibular ligament and the calcaneofibular ligament

23
Q

Lateral ligament is more likely to be damaged because:

A

Weaker than the medial Ligaments and resists Inversions

24
Q

If someone foot has been ran over what what kind of fracture can occur?

A

Talus fracture or midfoot fracture

25
Q

Which lateral ligament is most at risk for irreversible damage?

A

Anterior talofibular ligament

26
Q

What are the functions of the arches of the foot?

A

Spread forces of the foot

27
Q

What has the highest arch? medial or lateral?

A

medial

28
Q

What are the ligaments of arches of the foot?

A

Calcaneonavicular (spring ligament)

Plantar calcaneocuboid (short plantar ligament) &

long plantar ligament

29
Q

Which ligament maintains the longitudinal arches of the foot?

A

long and short ligaments

30
Q

What is the function of the plantar aponeurosis (thickening of the deep fascia of the foot)?

A

supports the longitudinal arch of the foot

31
Q

The posterior tibial artery continue on and splits at the sole of the foot as what arteries?

A

Lateral and medial plantar arteries

32
Q

The anterior tibial artery becomes what artery?

A

Dorsalis pedis artery
