ankle anatomy review Flashcards
tibia and fibular are concave or convex on the talus
concave on the convex talar dome
Talocrural
articulation between tibia/fibula and talus
Subtalar joint
articulation between the talus and calcaneus
does the Fibula have a function in WB
no - mainly serves as a muscle attachment
Rearfoot v. forefoot
talonavicular and calcanealcuboid joint mark the line of separation between the rearfoot and the forefoot
rearfoot
talus and calcaneus
- Forefoot
everything distal of the talus and calcaneus
- Midfoot
Midtarsal joint has 2 articulations 1. talo-navicular, 2. Calcaneal-cuboid
made up by these two jts
which brach deal with the majority of body weight
medial long - the arch is built to distribute loads
medial long distal to proximal
1st Metatarsal, 1st Cuneiform, Navicular, Calcaneus
medial long flexibility
It is flexible, and is allowed to deform with each ground contact…absorbing shock
medial long is supported by what what muscle tendons
tibialis anterior, tibialis posterior, and peroneus longus tendons.
distal to proximal lateral long brach
5th metatarsal – cuboid - calcaneus
Lateral to medial transverse arach
– Lateral cuneiform – middle cuneiform – medial cuneiform
Anterior tibiofibular - what injury
high ankle sprain
Anterior tibiofibular resists what kind of motion
DF + EV
Anterior Talofibular - injury
most common
Anterior Talofibular stressed in what movement
INV+PF
where do we find the Anterior Talofibular
lateral malleolus to the neck of talus
- Calcaneal fibular resist what movement
straight inversion
Calcaneal fibular where
tip of lateral malleolus to lateral surface of calcaneus
Posterior talofibular resist what motion
resist INV + DF
Posterior Tibiofibular helps with what
helps reinforce the posterior aspect of the distal tib-fib joint
subtler joint ligaments are more associated with what kind of injury
“chronic ankle sprains”
Cervical Ligament connects what
is a subtalar ligament
connecting the talus to the calcaneus
Cuneonavicular is what kind of ligament
plantar ligament
Cuneonavicular is from where to where
the cuneiform – navicular
Cuneonavicular provides what kind of reinforcement
reinforcement to the medial arch
Long Plantar helps to reinforce what part of the foot
medial arch
Long Plantar runs from where to where
Plantar surface of calcaneus to plantar surface of Cuboid
Plantar Fascia travels from
originates from the anterior medial calcaneal tubercle and expands out the toes
Anterior Compartment nerve
Deep Peroneal Nerve
Deep Peroneal Nerve levels
(L4-S1)
Superficial Peroneal N levels
L5 – S2
Anterior Compartment contains
Tibialis Anterior
Extensor Digitorum Longus
Extensor Hallicus Longus
all DF
Deep Posterior Compartment:
Tibialis Posterior
Flexor Digitorum Longus
Flexor Hallicus Longus
Deep Posterior Compartment innervation
Tibial N –
TP: L4-5
FDL: S2,3
FHL: S2,3
Superficial Posterior Compartment:
Plantaris
Gastrocnemius
Soleus
Superficial Posterior Compartment innervation
