What is the function of the bifurcate ligament ?

Answer 2

It joins the calcaneus to one part of the cuboid and also to the navicular bone (the 2nd bifurcation)

Question 3

Where is the dorsal calcaneocuboid ligament located ?

Question 4

It joins the calcaneus to the cuboid

Question 5

Where is the dorsal tarsal ligament located?

Question 6

What is the function of the dorsal tarsal ligament ?

Answer 6

It is a general name for ligaments that join neighbouring tarsals to each other, on the top of the foot

Question 7

Where is the dorsal tarsometatarsal ligament located?

Question 8

What is the function of the dorsal tarsometatarsal ligaments?

Answer 8

It binds the distal row of tarsals to the base of the metatarsals, on the top of the foot

Question 9

Where is the dorsal metatarsal ligament located?

Question 10

What is the function of the dorsal metatarsal ligament?

Answer 10

It binds the bases of the metatarsals together, on the top of the foot

Question 11

Where is the deep transverse ligament located?

Question 12

What is the function of the deep transverse ligament ?

Answer 12

It holds the distal ends of the metatarsals together

Question 13

Where is the spring ligament/plantar calcaneonavicular ligament located ?

Question 14

What is the function of the spring ligament ?

Answer 14

It maintains the (medial) longitudinal arch of the foot

Question 15

Where is the interosseous talocalcaneal ligament located ?

Question 16

What is the function of the interosseous talocalcaneal ligament ?

Answer 16

It binds the calcaneus and talus together. It is also important on inversion-eversion movements

Question 17

Where is the plantar aponeurosis (fascia) located?

Question 18

What is the function of the plantar aponeurosis (fascia)?

Answer 18

It helps maintain the foot’s longitudinal arch and also the windlass effect

Question 19

Where is the Long plantar ligament located ?

Question 20

What is the function of the long plantar ligament ?

Answer 20

Helps maintain the foot’s longitudinal arches (mostly the lateral)

Question 21

Where is the short plantar ligament located?

Question 22

What is the function of the short plantar ligament ?

Answer 22

Helps maintain the foot’s longitudinal arches (mostly the lateral)

Question 23

Where is the deep transverse metatarsal ligament located ?

Question 24

What is the function of the deep transverse metarsal ligament ?

Answer 24

It binds the heads of the metatarsals together

Question 25

Which ligament in the foot is most easily seen from above?

Answer 25

The Spring ligament - with an opened calcaenonavicular joint

Question 26

What is the tarsal sinus ?

Answer 26

It is the space between the talus and the calcaneus, on the lateral side. All sinuses are just cavities/spaces

Question 27

Why is the tarsal sinus important for physios?

Answer 27

Clinicians inject it so we need to know what it is and where it is

Question 28

How is the tarsal sinus formed ?

Answer 28

It is formed by the articulation of the talus with the calcaneus, with both bones having a groove/sulcus in them. Where the two grooves join, a space is formed

Question 29

What ligament is attached to the tarsal sinus ?

Answer 29

Interosseous talocalcaneal ligament
