Talus Flashcards
What attaches to the talus?
trick question!
no muscles or tendons attach to the talus
what is the superior surface of the body of the talus called?
trochlea
what does the trochlea articulate with?
- tibial plafond (inferior surface of tibia)
- medial malleolus (of tibia)
- lateral malleolus (of fibula)
- anterior (inferior) tibiofibular ligament
- inferior transverse ligament
Where is the posterior articular facet of the talus found?
inferior surface of the body of the talus
-it articulates with the calcaneus
what is the name of the deep groove that is located at the union of the body and neck of the talus?
sulcus tali
where is the comma-shaped facet located? and what is its articulation for?
medial surface of the body of the talus; articulates with the medial malleolus
*mnemonic- “comma in the medial of the sentence”
Which way does the apex point of the triangular shaped lateral surface of the body of the talus?
apex points inferiorly
What surface on the talus articulates with the lateral malleolus?
“the lateral process”- the inferior, tapered end of the lateral surface
the posterior surface of the talus is aka what?
posterior process
the posterior process of the talus is grooved by which tendon?
tendon of flexor hallucis longus
what divides the posterior process into two tubercles: medial and lateral?
the tendon of the flexor hallucis longus
What attaches to the medial tubercle of the posterior process of the talus?
- medial talocalcaneal ligament
2. posterior tibiotalar ligament (part of the deltoid ligament)
what 3 ligaments attach to the lateral tubercle of the posterior process of the talus?
- posterior talofibular
- posterior talocalcaneal
- fibulotalocalcaneal
Where is the os trigonum found?
accessory bone on the lateral tubercle of the posterior process of the talus
what structures on the talus and calcaneus come together to form the tarsal sinus/canal?
sulcus tali (on talus) and the calcaneal sulcus
