-
What is the talocrual joint? Give 1 char. When is it the most stable?
- Articulation of the tibia and fiubla with the talus
- Synovial-hinge type
- It is more stable in dorsiflexion than plantar flexion due to a wider talus bone anteriorly than posteriorly.
-
What are the lateral collateral ligaments of the ankle joint (talocrural)? List them and describe. (3)
three ligaments that attach the lateral malleollus to the talus and calcaneous.
- Anterior talofibular ligament- runs from the lateral malleolus to the neck of the talus.
- Posterior talofibular ligament-runs from the lateral malleolus to the lateral tubercle of the posterior process of the talus.
- Calcaneofibular ligament- runs from the lateral malleolus to the lateral surface of the calcaneuous.
-
What is another name for the medial collateral ligaments of the talocural joint? Describe it. List them.
- Deltoid;
- It consists of four parts that attaches the medial malleolus to the talus, calcaneuous and navicular. The parts are named for their bony attachments.
- Anterior tibiotalar ligament
- Posterior tibiotalar ligamentTibionavicular ligament
- Tibiocalcaneal ligament
-
What is the blood supply to the talocrual joint? Nerve supply?
- Anterior and posterior tibial arteries
- Tibial nerve and deep peroneal nerve.
-
what is the subtalar joint? Is it synovial? What is the function of the subtalar joint?
- Articulation of the talus and the calcaneuous. Yes;
- Permits inversion and eversion of the foot.
-
What is another name for the transverse tarsal joint? What two joints does it consist of?
- Midtarsal joint.
- Talocalcaneonavicular and calceocuboid joint.
-
What kind of joint is the talocalneonavicular joint? What is the name of its ligament? Another name for it? What are its attachments? what is its function?
- Synovial ball and socket joint
- plantar calcaneonavicular ligament; spring ligament
- Band that extends from the sustentaculum tali to the posterior surface of the navicular bone;
- It plays an important role in maintaing the longitudnal arch of the foot. fyi. The plantar aponeurosis also helps with the longitunal arch of the foot.
 
-
What are the two ligaments of the synovial calcaneocuboid joint? Describe each of them (attachments and function).
-
List 4 structures that help with the longitudinal arch of the foot.
- Plantar aponeurosis
- Plantar calcaneonavicular ligament (spring ligament)
- Long plantar ligament
- Short plantar ligament (plantar calcaneocuboid ligament)
-
list (3) things that support the transverse tarsal joint on the dorsal surface.
- Dorsal talonavicular ligament
- Bifurcated ligaments- Calcaneocuboid and calcaneonavicular
