Question 11

Talocrural joint

aka
joint type
permits

Answer 11

aka ankle joint

hinge type synovial joint b/w tibia and talus

permits plantarflexion and dorsiflexion

Question 12

Calcaenofibular ligament

attachment
f(x)

Answer 12

attachment: from tip of the lateral malleolus to the lateral surface of the calcaneus
f(x): stabilize the foot, prevent inversion injury

Question 13

Forced inversion of the foot tears what ligament

Answer 13

calcaneofibular ligament

Question 14

Describe the course of the common fibular nerve

Answer 14

it winds around the neck of the fibula before dividing into superficial and deep branches

Question 15

Lateral Plantar Nerve

Innervates

Answer 15

adductor hallucis, plantar interossei (all intrinsic muscles in the sole of the foot except for those supplied by the medial plantar nerve)

Question 16

Medial Plantar Nerve

Answer 16

major sensory nerve of the foot

innervates skin on the anterior 2/3 of the sole, and 4 instrinsic muscles

Question 17

Achilles tendon inserts at

Answer 17

the calcaeus

Question 18

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

Answer 18

anteriortalofibular & calcaneofibular ligaments

Question 19

Plantar calcaneonavicular ligament

aka
f(x)

Answer 19

spring ligament

supports the head of the talus and maintains the arch of the foot

Question 20

Sprain of the deltoid ligament is caused by

Answer 20

eversion of the ankle joint

Question 21

What causes flat foot?

Answer 21

flattening of the medial longitudinal arch

Question 22

Potts Fracture

Answer 22

medial malleolus is pulled forcefully by the strong deltoid ligament as the talus moves laterally, causing a fracture of the medial malleolus
