ligaments, bursa, spaces and other structures
name the ligaments of the ankle and foot
anterior talofibular ligament
calcaneofibular ligament
deltoid ligament
posterior talofibular ligament
what bursa is located in the ankle/foot?
retrocalcaneal bursa
where does the ATFL of the ankle run?
from lateral malleolus (tip of fibula) to the neck of the talus
during what movement of the ankle is the ATFL taut?
PF
what movements of the ankle does the ATFL resist?
inversion of the talus and calcaneus
anterior translation of the talus on the tibia
where does the posterior talofibular ligament of the ankle run?
from the lateral malleoar fossa (groove of fibula) to the lateral tubercle on the posterior surface of the talus
what movement of the ankle does the PTFL resist?
posterior displacement of the talus on the tibia
where does the calcaneofibular ligament of the ankle run?
from the tip of the lateral malleolus (tip of fibula) to the lateral surface of the calcaneus
what complex within the ankle is the calcaneofibular ligament part of?
the lateral collateral ligament complex
what type of ligament is the calcaneofibular ligament of the ankle?
an extracaupsular ligament
what motion of the ankle does the calcanofibular ligament resist?
inversion of the talus within mid range talocrural motion
where does is the deltoid ligament of the ankle run?
from medial malleolus of the ankle to the tibia, navicular, talus and calcaneus bones
what shape is the deltoid ligament?
triangular
what ligaments is the deltoid ligament formed by?
anterior tibiotalar ligament
tibiocalcaneal ligament
postierior tibiotalar ligament
tibionavicular ligament
the deltoid ligament of the ankle provides __ ligamentous support by resisting eversion of the __
medial; talus
the majority of ligaments in the ankle are actually areas of __ __ within the joint capsule
as a result, damage to the ankle ligaments typically produces damage to the __ __ and irritation of the __ __
increased density
join capsule; synovial lining
what ankle ligament is taught during PF resists inversion of the talus and calcaneus as well as anterior translation of the talus on the tibia?
ATFL
what ligament of the ankle is an extracapsular ligament that resists inversion of the talus within midrange talcrural motion
calcaneofibular ligament
what ankle ligament is formed by the anterior and posterior tibiotalar ligaments, tibionavicular ligament and tibiocalcaneal ligaments and provides medial ankle stability by resisting talar eversion?
deltoid ligament
what ankle ligament resists posterior displacement of the talus on the tibia?
PTFL
what is the name of the bursa within the ankle/foot?
retrocalcaneal bursa
where is the retrocalcaneal bursa located within the ankle/foot?
just anterior to the achilles tendon where it attaches to the superior calcaneus
what is the function of the retrocalcaneal bursa?
it acts as a cushion between the tendon and its bone
irritation of the retrocalcaneal bursa due to trauma or over use can result in what condition?
retrocalcaneal bursitis
