A

Provide lateral support to ankle. Resist inversion

37
Q

The plantar calcaneonavicular (spring) ligament attaches the

A

Sustenaculum tali and navicular bone

38
Q

The plantar calcaneonavicular (spring) ligament function to

A

39
Q

The long plantar ligament attaches

A

Calcaneus, cuboid, and lateral 3 metatarsals

40
Q

The long plantar ligament functions to

A

Provide lateral arch support to foot

41
Q

The movements of dorsiflexion and plantarflexion occur between the

A

Trochlea of talus and medial malleolus of tibia and lateral malleolus of fibula

42
Q

The movements of inversion and eversion occur at both the

A

Subtalar and transverse tarsal joints

43
Q

Which leg muscles function in dorsiflexion?

A

Tibialis Anterior, Extensor Hallucis Longus, Extensor

Digitorum Longus

44
Q

Which leg muscles function in plantarflexion?

A

Gastrocnemius, Soleus, Tibialis Posterior, Flexor

Digitorum Longus, Flexor Hallucis Longus

45
Q

Which leg muscles function in inversion?

A

Tibialis anterior and tibialis posterior

46
Q

Which leg muscles function in eversion?

A

Peroneus longus and peroneus brevis

47
Q

The blood supply to the ankle and sole of the foot is via branches of the

A

Posterior tibial artery (called the medial and lateral plantar arteries)

48
Q

The dorsum of the ankle and foot is supplied by the

-branch of anterior tibial artery

A

Dorsalis pedis artery

49
Q

Ankle sprains are common occurences, with most being inverted sprains that stretch or tear the

A

Lateral collateral ligament of the ankle

50
Q

The lateral collateral ligaments tend to tear from

A

Anterior to posterior with increasing severity

51
Q

A painful inflammation of the plantar fascia that results from micro tears of the fascia due to repeated stress

A

Plantar fasciitis

52
Q

A very common foot deformity in which the proximal phalanx of the big toe deviates laterally and the first metatarsal deviates medially

A

Hallux valgus

53
Q

What happens in hallux valgus?

A

Proximal phalanx of big toe deviates laterall and first metatarsel deviates medially

54
Q

Friction leads to swelling of the bursa overlying the medial site of the metatarsal head, creating a

A

Bunion

55
Q

Injury of compression of the leg can lead to compartment syndrome because the crucial fascia is so tight. This would be relieved by a

A

Fasciotomy

Q

Joint between talus and calcaneus.

A

Subtalar joint

57

Q

We get motions of inversion and eversion at the

A

Subtalar and Transverse tarsal joints

59
Q

When the foot is dorsiflexed, abducted, and exerted we have

A

Pronation

60
Q

When the foot is plantarflexed, addicted, and inverted we have

A

Supination

61
Q

Pronation of the foot results in

A

Inner heel sole wear

62
Q

Supination of the foot results in

66
Q

The superficial artery of the foot

A

Lateral plantar

67
Q

If you have occlusive disease in aortoiliac artery, there would be pain in the

A

Thigh and Buttock (also trouble maintaining erection)

68
Q

Femoral occlusive disease would result in pain in the

A

Calf

69
Q

Occlusive disease in popliteal or proximal tibial or fibular arteries presents with

A

Foot pain

70
Q

What are the three joints of the ankle and what do they predominantly do?

A
  1. ) Talocrural (dorsiflexion and plantarflexion
  2. ) Subtalar (inversion and eversion)
  3. ) Transverse tarsal (midfoot inversion and eversion)
71
Q

Which ligament from the ankle’s LCL is most likely to be injured in an ankle sprain?

A

Anteriotalofibular ligament

72
Q

Runs from the talus to the fibula and resists inversion

A

Anteriotalofibular ligament

73
Q

The plantar fascia is analogous to the palmar aponeurosis, and where it attaches to the calcaneus is the location of

A

Plantar fasciaitis

74
