Q

We also have metatarsals and tarsals: name the joints and structures present

A

Joints:
-metatarsal phalangeal joints
- interphalangeal joints

Metatarsal structure:
- head on distal end (makes metatarsal phalangeal joint)
-shaft
- base, these meet up with the tarsals

Q

Describe characteristics of the talocrural joint

A
  • joins talus and leg bones (tibia and fibula)
  • the grip shape where talus will fit is called the mortis
  • the part of the talus that fits in there is called the dome of the talus
  • the joint has lots of bony congruency:) love this bc it means it’s stable!
  • PLANTARFLEXION AND DORSIFLEXION

Q

Describe characteristics of the subtalar joint

A
  • convex surface of upper calcaneus meets 5e concave surface on bottom end of talus
  • INVERSION ANS EVERSION (pulls apart 3 ligaments)

16
Q

Describe the anterior talo-fibular ligament

A

Attaches to talus, lateral aspect and fibula at the lateral malleolus
STRETCHED WITH INVERSION, PLANTARFLEXION

17
Q

Describe the calcaneofibular ligament

A

Comes in from lateral aspect of calcaneus and bottom of lateral malleolus on fibula
LIMITER OF INVERSION

18
Q

Describe the posterior talk fibular ligament

A

Attaches to posterior aspect of talus to lateral malleolus on fibula
PREVENTS INVERSION AND DORSIFLEXION

19
Q

What ligament limit ankle eversion?

A
  • anterior tibiotalar ligament
  • tibionavicular ligament
  • tibiocalcaneal ligament
  • posterior tibiotalar ligament
20
Q

Describe the anterior tibiotalar ligament

A

Comes down from medial malleolus of tibia and talus on medial side
LIMITS EVERSION BEST WHEM PLANTARFLEXED, sits anteriorly

21
Q

Describe the tipbionavicular ligament

A

From tibia to navicular, duh hehe
LIMITS EVERSION BEST WHEN PLANTARFLEXED

22
Q

Describe the tibiocalcaneal ligament

A

Narrow
- comes down to sustentaculum talk from medial malleolus on tibia

23
Q

Describe the posterior tibiotalar ligament

A
  • tibia to posterior aspect of talus
  • LIMITS EVERSION and DORSIFLEXION
24
Q

What ankle injuries are more or less common (which side) and why?

A

EVERSION less common, stronger, broader, larger ligaments = less sprains on EVERSION side

25
Q

Describe the tibiofibular joint

A
  • different bc not a lot of motion happens here
  • joint is filled with ligament and collagen, not a lot of motion
26
Q

What are some ligaments that hold the tibia and fibula together and why are they necessary?

A

Anterior tibiofibular ligament, posterior tibiofibular ligament and transverse tibiofibular ligament

STRONG, if the fibula moved away and separated, it would lose the shape of the mortis that holds onto the talus
INSECURE TIBIOFIBULAR JOINT = INSECURE TALOCRURAL JOINT = NO STRUCTURAL INTEGRITY

27
Q

Which ligaments help in supination of the foot?

A

Plantar calcaneonavicular ligament
- calcaneus to navicular
- has a little more elastin, stretch and recoil
- helpful cause pronation will stretch his ligament apart and this helps to bounce back into supination

Plantar aponeurosis or fascia
- refers to tissue that’s weblike, spreads out across different insertions, mot as focused as ligaments
- first attachment at calcaneal tuberosity and has individual extensions into each of the toes into bases of proximal phalanges, loading the foot will stretch this and relax it during supination
- plantar fasciitis is an injury here
