compartment syndrome

Answer 11

increases pressure in fixed space of lower leg which causes neural and vascular structure compression

Question 29

posterior talofibular ligament

Answer 29

9 o'clock

Question 30

deltoid ligament

Answer 30

medial side, broad and strong

Question 31

anterior/posterior tibiofibular ligaments

Answer 31

stabilize distal tibia/fibula | high ankle sprain

Question 32

subtalar joint

Answer 32

inversion/eversion | between talus and calcaneus

Question 33

ankle sprain

Answer 33

usually when ankle is plantarflexed + sudden inversion

runs from calcaneal tubercle to proximal phalanx of each digit

Question 38

long plantar ligament

Answer 38

connects rearfoot to midfoot
