Ankle: Anatomy 1 Flashcards
Functionally, the foot can be broken down into 3 sections:
- hindfoot (rearfoot)
- midfoot (midtarsal joint)
- forefoot
Hindfoot is composed of
- talus
- calcaneus
Midfoot is composed of
- navicular
- cuboid
- cuneiforms
Forefoot is composed of
- metatarsals
- phalanges
Foot: medial column is composed of
- talus
- navicular
- 3 cuneiforms
- metatarsals 1-3 with phalanges
Foot: lateral column is composed of
- calcaneus
- cuboid
- metatarsals 4-5 with phalanges
What are the major joints of the foot?
- talocrural
- subtalar
- Chopart’s joint
- Lisfranc’s joint
What composes the talocrural joint?
- talus
- distal tib/fib
Chopart’s joint connects what to what
hindfoot to midfoot
Chopart’s (transverse tarsal) joint includes these two joints
- calcaneocuboid
- talonavicular
Lisfranc’s joint connects what to what?
midfoot to forefoot
Lisfranc’s joints include these joints
tarsomatatarsal joint
Tibiofibular joint: resting position
PF
Tibiofibular joint: close packed position
max DF
Tibiofibular joint: capsular pattern
pain when joint is stressed
Tibiofibular ROM: PF
50˚
Tibiofibular ROM: DF with knee extended
10˚
Tibiofibular ROM: DF with knee flexed
20˚
TCJ: resting position
10˚ between plantarflexion midway between inversion and eversion
TCJ: close packed position
max DF
TCJ: capsular pattern
PF > DF
STJ: resting position
midway between extremes of ROM
STJ: close packed position
supination
STJ: capsular pattern
limited ROM (varus, valgus)
