Arthrology of the ankle Flashcards
What is the attachment for the medial collateral ligament or the Deltoid Ligament?
From the medial malleolus of the tibia to the talus, navicular, and sustentaculum of the calcaneus
Function of the Medial collateral (deltoid)
stabilizes joint and resists eversion
What are the three lateral ligaments of the ankle?
Posterior talofibular
Anterior talofibular
Calcaneofibular
Posterior talofibular attachment
From the malleolar fossa of the fibula to the lateral tubercle of the talus
What is the function of the ant. and post. talofibular lig.
Resists talocrural inversion
What is the attachment of the anterior talofibular ligament?
anterior lateral malleolus of the fibula to the neck of the talus
What is the function of the anterior talofibular ligament?
Resists talocrural inversion
AND resists anterior translation of the talus
Calcaneofibular attachment
lateral malleolus to the lateral surface of the calcaneus
Function of the calcaneofibular joint
resists calcaneal/subtalar inversion
What are the attachments of the long plantar ligament?
From the plantar surface of the calcaneus & cuboid to the plantar surface of the bases of the metatarsals
Short plantar ligament (plantar calcaneocuboid ligament) attachments
from the calcaneus to the plantar surface of the cuboid
Spring ligament (plantar calcaneonavicular) attachments
From the sustentaculum tali to the plantar surface of the navicular
Spring ligament (plantar calcaneonavicular) function
supports medial longitudinal arch of the foot
What is the attachment for the Talocrural Capsule
From the Boarders of the articular surface of the tibia and malleoli to the margins of the trochlear surface of the talus
What structure experienced WB from the tibia and fibula
Talus
Where is the Tibiofibular syndesmosis and what action leads to gapping or separation?
Distal tibiofibular joint
Posterior glide of the talus in mortise
DF
What type of joint is the Distal tibiofibular
Syndesmosis /plane/gliding:
What type of joint is the Talocrural joint?
Hinge
What type of joint is the Subtalar joint
plane
What type of joint is the Tarsometatarsal ?
plane
What type of joint is the metatarsalphalangeal ?
Ellipsoidal
What type of joint is the interphalangeal joint ?
hinge
What are the Lateral lig, of the a ankle
ATFL, PTFL,CFL
Pronation non WB (calcaneus on talus)
Calcaneal Eversion
Calcaneal abduction
Calcaneal DF
High ankle sprain : DF + rotation+ eversion causes what two structures to be injured
Injury to the anterior inferior tibiofibular lig. and or syndysmosis
Supination non WB (calcaneus on talus)
Calcaneal Inversion
Calcaneal Adduction
Calcaneal PF
Pronation in WB
Cancaneal eversion
Talar adduction
Talar PF
Supination in WB
Calcanius inversion
Talar Abduction
Talar DF
What type of glide would help with PF?
Anterior glide of the talus
What provides support to the distal tibiofibular lig.
Anterior inferior tibiofibular ligament
Interosseous membrane
What provides stability to the distal tibiofibular joint
Anterior Inferior tibio
What is the mechanism of a high ankle sprain ?
DF+ eversion + rotation
Injury to the an. tibiofibular lig. and or syndesmosis
