Q

Subtalar joint: articulations

A
  • formed by 3 articulations (anterior, posterior, and middle) between talus and calcaneus
  • 1 degree of freedom
  • anterior and middle are formed by 2 convex facets on talus/2 concave on calcaneus
  • posterior formed by concave facet on inferior surface of talus and convex on body of calcaneus

Q

Midtarsal joint: All the stuff

A
  • midtarsal (transverse tarsal) joint formed by talocalcaneonavicular joint and calcaneocuboid joint
  • joint has 2 axes: longitudinal and oblique
  • motions around both axes are triplanar

A

DF, PF, adduction, medial rotation

18
Q

Joint that make up the forefoot

A
  • tarsometatarsal
  • metatarsophalangeal
  • interphalangeal
19
Q

Muscles responsible for plantarflexion

A
  • tibialis posterior
  • gastroc
  • soleus
  • peroneus longus and brevis
  • plantaris
  • flexor hallucis
20
Q

Muscles responsible for dorsiflexion

A
  • tibialis anterior
  • extensor hallucis longs
  • extensor digitorum longs
  • peroneus tertius
21
Q

Muscles responsible for inversion

A
  • tibialis posterior
  • tibialis anterior
  • flexor digitorum longus
22
Q

Muscles responsible for eversion

A
  • peroneus longus
  • peroneus brevis
  • peroneus tertius
23
Q

Anterior Talofibular Ligament (ATFL)

A
  • taut during PF
  • resists inversion of talus and calcaneus
  • resist anterior translation of talus on tibia
24
Q

Calcaneofibular Ligament (CFL)

A
  • extracapsular ligament

- resists inversion of talus w/in midrange of talocrural motion

25
Q

Posterior Talofibular Ligament (PTFL)

A
  • resists posterior displacement of the talus on the tibia
26
Q

Deltoid Ligament

A
  • formed by the anterior tibiotalar ligament, tibiocalcaneal ligament, posterior tibiotalar ligament, and tibionavicular ligament
  • provides medial support by resisting eversion of the talus
27
Q

Interosseous Membrane

A
  • consists of a strong fibrous tissue
  • serves to fixate fibula to the tibia
  • distally, the structure blends into the anterior and posterior tibiofibular ligaments
  • provides additional support at the distal tibiofibular syndesmosis joint
28
Q

Convex/Concave:
Convex- anterior and middle talus
Concave- anterior and middle calcaneus

Convex- posterior calcaneus
Concave- posterior talus

Osteokinematic/Arthrokinematic: opposite and same depending on intent for manual therapy

31
Q

Intermetatarsal joints: resting, convex/concave, osteokinematic/arthrokinematic motions for MT

A

Resting: midway between extremes of ROM

Convex/Concave:
Convex- more medial metatarsals

Osteokinematic/Arthrokinematic: same direction

32
Q

A

Resting: neutral

Convex/Concave:
Convex- metatarsals
Concave- phalanges

33
Q

Interphalangeal joints: resting, convex/concave, osteokinematic/arthrokinematic motions for MT

A

Resting: slight flexion

Convex/Concave:
Convex- proximal phalanges
Concave- distal phalanges

Osteokinematic/Arthrokinematic: same direction
