Dorsiflexion/inversion

17
Q

Tibialis posterior?

A

Very deep muscle!!!

Posterior surface of tibia/fibula

Tuberosity of navicular/plantar of 3 cuneiforms/1st-3rf metatarsal bases

Inversion/plantarflexion

18
Q

calcaneocuboid joint?

A

distal calcaneus/proximal cuboid

saddle joint

rotation during inversion/eversion

CAN BE PALPATED LATERALLY

19
Q

talonavicular joint?

A

distal talus/proximal navicular

circumduction, inversion/eversion of ankle

20
Q

subtalar joint?

A

HARD TO PALPATE AS COVERED

posterior talus/articular facet of calcaneus

21
Q

CFL?

A

lateral malleolus posteroinferiorly

tubercle on lateral of calcaneus

controls eversion-slack whilst standing

22
Q

ATFL?

A

anteroinferior lateral malleolus

lateral of talus

prevents foot sliding forward

23
Q

deltoid ligament?

A

strong triangular ligament

anterior+posterior borders of medial malleolus tip

talus/navicular

prevents external rotation of talus+strength

24
Q

PTFL?

A

posterior of tibia+fibula

medial tubercle of posterior talus

25
Q

ankle joint?

A

distal tibia, proximal of body of talus, medial of lateral malleolus of fibula

hinge synovial joint allowing for plantarflexion, dorsiflexion, inversion and eversion

26
Q

inferior tibiofibular joint?

A

fibular notch of lateral tibia+ medial fibula

gliding motions to assist ankle joint

27
Q

MTP joints?

A

synovial condyloid joints

convex meta heads+concave phalanx bases

plantarflexion, abduction, adduction, circumduction

28
Q

IP joints?

A

head of more proximal phalanx+ base of more distal

bases of each are pulley shaped

allow planterflexion+dorsiflexion
