ankle joint Flashcards
what type of joint is the ankle joint
synovial joint
which bones are involved in the ankle joint
- talus
- tibia
- fibula
which movements does the ankle joint mainly allow
hinge- like dorsiflexion and plantarflexion
roof of socket between talus and tibia and fibula
inferior surface of distal end of tibia
medial side of socket between talus and fibula and tibia
medial malleolus of tibia
lateral side of socket between talus and fibula and tibia
lateral malleolus of fibula
which surface of the talus moves into the ankle joint when the foot is dorsiflexed
the wider surface
which part of the talus moves in the ankle joint when the foot is plantarflexed
the narrower part
is the ankle joint most stable when the foot is dorsiflexed or plantarflexed
dorsiflexed
is the articular surface of the talus wider anteriorly or posteriorly
anteriorly
what is the apex of the deltoid ligament (medial ligament) of the ankle attached to above
the medial malleolus
what is the broad base of the medial ligament (deltoid ligament) attached to below
a line that extends from the tuberosity of the navicular bone in front to the medial tubercle of the talus behind
what 4 parts does the medial ligament (deltoid ligament) consist of
- tibionavicular part
- tibiocalcaneal part
- posterior tibiotalar part
- anterior tibiotalar part
what does the plantar calcaneonavicular ligament (spring ligament) connect
the navicular bone with the sustentaculum tali of the calcaneous bone
where does the tibionavicular part of the medial ligament attach to in front
to the tuberosity of the navicular and the associated margin of the plantar calcaneonavicular ligament
what does the tibiocalcaneal part of the medial ligament attach to
the sustentaculum tali of the calcaneus bone
what does the posterior tibiotalar part of the medial ligament attach to
the medial side and medial tubercle of the talus
what does the anterior tibiotalar part of the medial ligament attach to
the medial surface of the talus
what does the anterior talofibular ligament attach to
the anterior margin of the lateral malleolus and the adjacent region of the talus
how does the posterior talofibular ligament run
horizontally backward and medially from malleolar fossa to posterior process of talus
what does the calcaneofibular ligament attach to
the malleolar fossa and a tubercle on the lateral surface of the calcaneus
