Cuboid

Question 1

Cuboid location

Answer 1

lateral bone in distal row of tarsal bones

oriented so superior surface is directed superolateral and inferior surface is inferomedial

Question 2

Ligaments attached to superior cuboid surface (6)

Answer 2

dorsal calcenocuboid
dorsal cuneocuboid
dorsal cuboideonavicular
dorsal cuboideometatarsal to fourth metatarsal
dorsal cuboideometatarsal to fifth metatarsal
lateral calcaneocuboid (variable)

Question 3

Coronoid process of cuboid

Answer 3

located on plantar surface where medial and posterior borders meet

Question 4

Features of plantar surface of cuboid

Answer 4

peroneal sulcus and peroneal ridge
both course obliquely from posterolateral to anteromedial
sulcus lies distal to ridge

Question 5

Where does tendon of peroneus longus lie?

Answer 5

Either in peroneal groove or against anterior aspect of peroneal ridge

Question 6

What attaches to the peroneal ridge?

Answer 6

Deep fibers of the long plantar ligament`

Question 7

Superficial fibers of the long plantar ligament ….

Answer 7

course over tendon of peroneus longus

long plantar ligament and cuboid form osseofibrous canal for peroneus longus tendon

Question 8

Structures attached to plantar surface of cuboid (8)

Answer 8

long plantar ligament
short plantar ligament 
plantar cuboideonavicular ligament
tibialis posterior 
flexor hallucis brevis
plantar cuneocuboid ligament
plantar cuboideometatarsal to fourth metatarsal
plantar cuboideometatarsal to fifth metatarsal

Question 9

Cuboid tuberosity

Answer 9

lateral termination point of peroneal ridge

contains oval facet facet for sesamoid bone

Question 10

What sesamoid bone articulates with the facet of the cuboid tuberosity
What tendon is it located in

Answer 10

Os peroneum

tendon of peroneus longus

Question 11

Lateral cuboid surface

Answer 11

smallest surface - more of a border

Question 12

Where is the peroneal notch located?

Answer 12

Plantar edge of the lateral surface

marks the beginning of the peroneal sulcus

Question 13

Medial cuboid surface

Answer 13

quadrilateral
contains triangular facet for lateral cuneiform at dorsal middle portion
sometimes small facet for navicular

Question 14

Ligaments attaching to medial cuboid surface (3)

Answer 14

interosseous cuboideonavicular ligament
interosseous cuneocuboid ligament
calcaneocuboid portion of bifurcated ligament

Question 15

Posterior cuboid surface

Answer 15

contains triangular facet for calcaneus
saddle shaped (concave transversely and convex vertically)

Question 16

Anterior cuboid surface

Answer 16

contains vertical ridge that separates two facets

Question 17

Medial facet of anterior cuboid

Answer 17

quadrilateral

for articulation with base of fourth metatarsal

Question 18

Lateral facet of anterior cuboid

Answer 18

triangular
apex directed laterally
for articulation with fifth metatarsal
