FOOT - bones

Question 0

calcaneus

Answer 0

tuberosity
sustenaculum tali (below medial malleolus)
peroneal trochlea ( below lateral malleolus)

Question 1

medial & lateral malleoli

Answer 1

medial is higher than lateral

malleolar groove

Question 2

talus

Answer 2

head (proximal to navicular tubercle)
trochlea (anteriorly halfway between malleoli, more prominent laterally)
medial tubercle (45degree posterior off medial malleolus, slides around the medial malleolus during plantarflexion & dorsiflexion)

Question 3

hallucis

Answer 3

only 2 phalanges
IP joint = hinge joint
1st metacarpophalangeal joint = ellipsoid (allows some abd/adduction & flexion & extension

Question 4

1st metatarsal

Answer 4

short & stalky

proximal end articulates with medial cuneiform (bump on the dorsum of foot - often aggravated by tight lacing of laces)

Question 5

2nd-5th metatarsals

Answer 5

long & slender w/ enlarged base & head
bases - connect w/ tarsals
spaces between metatarsals contain small intrinsic muscles of the foot (easily palpated from dorsal aspect)

Question 6

tuberosity of 5th metatarsal (base of the 5th)

Answer 6

large knob where peroneus brevis attaches

avoid this area when taping

Question 7

2nd-5th phalanges

Answer 7

3 bones each
PIP = proximal interphalangeal joint
DIP = distal interphalangeal joint

Question 8

medial, middle, lateral cuneiforms

Answer 8

between navicular and metatarsals
medial - attachment site - tibialis anterior & tibialis posterior
middle & lateral are between the medial cuneiform & cuboid (palpated along dorsal surface)
medial - proximal to base of 1st metatarsal, feel drop off
middle & lateral - lateral to medial one

Question 9

navicular

Answer 9

bean shaped
between medial/middle cuneiforms & talus
dorsal & medial surfaces are palpable
superficial tuberosity bulges on medial side of foot - tibialis posterior & spring ligament attaches
should be more proximal than the base of the 5th metatarsal when viewed from dorsum of foot

Question 10

cuboid

Answer 10

cube shaped
surrounded on 3 sides by: 4-5th metatarsals, lateral cuneiform, calcaneus
dorsal surface - partially covered by belly of extensor digitorum brevis
located diagonally between lateral malleolus & base of 5th metatarsal, closer to base of 5th
