talus/astragulus

talus articulates with

tibia, fibula, calcaneus, and navicular


NOT THE CUBOID

describe the lateral maleollar surface

its a surface on the body of the talus. it has a a lateral process. it articulates with the lateral maleollar articular surface of the fibula.

medial malleolar surface has a ____shaped facet

comma

describe the posterior surface of the talus?

has a posterior process of the talus which has 2 tubercles (medial and lateral) that are separated by a groove. the groove is the sulcus for the FHL. the lateral tubercle is larger than the medial tubercle.

what is on the inferior surface of the body of the talus?

a large rectangular shaped facet called the posterior calcaneal articular facet. it runs anterolateral. Its concave running down and flat side to side. it articulates with the posterior talar articular facet on the dorsal surface of the calcaneus.

the head of the talus is ___ and ___ in all directions. its long axis runs____

ovoid and convex


inferomedially

what is the surface of the head of the talus called?

navicular articular surface

describe the navicular articular surface

it extends plantarly and is separated into 2 facets called the anterior and middle calcaneal articular facets.


this is on the TALUS

there is a small triangular area that is anteromedial to the anterior and middle calcaneal articular facets on the head of the talus...what is this?

it articulates with a fibrocartilagenous facet of the spring ligament

where is the sulcus tali?

its a deep groove on the inferior surface of the neck of the talus

roof and floor of sinus tarsi

roof= sulcus tali


floor= calcaneus sulcus (groove on superior surface of the calcaneus)

blood supply to the head of the talus

braches of the anterior tibial artery and/or dorsalis pedis

blood supply to the body of the talus

anastomosis in the sinus tarsi of the artery of the sinus tarsi and the artery of the canalis tarsi.

what's the other name for calcaneus?

os calcis---its not an accessory bone!

calcaneus articulates with___

talus and cuboid

neutral triangle

area just inferior to the calcaneal sulcus that is deficient of trabeculae and is the weakest part of the bone

posterior talar articular surface

its on the CALCANEUS


its on the 1st smooth area on the superior surface of the calcaneus

whats significant about the 2nd smooth area?

has the anterior and middle talar articular facets


THIS IS ON THE CALCANEUS

sustentaculam tali

the middle calcaneal articular facet rests on this shelf of the bone

where is the calcaneal sulcus?

its on the 2nd rough area on the superior surface of the calcaneus

where is the calcaneal tuberosity?

its on the plantar surface of the calcaneus and is divided by a notch into medial and lateral processes. the medial process is larger.

anterior tubercle of the calcaneus

on the plantar surface of the calcaneus

describe the lateral surface of the calcaneus

shaped like an old shoe. surface bulges in the center and forms the retrochlear eminence. anterior to it is the peroneal trochlea.

decribe the medial surface of the calcaneus

has the sustentaculum tali and sulcus for the FHL

deep retrocalcaneal bursa

between the achilles and the calcaneus

superficial retrocalcaneal bursa

between the skin and the achilles

where is the articular facet for the cuboid?

on the anterior surface of the calcaneus

anterior process of the calcaneus

area where the superior, lateral and anterior surfaces meet and project over the cuboid

cuboid articulations

calcaneus, 4th and 5th met bases, lateral cuneiform, navicular

the dorsal surface of the cuboid runs____ and is continuous with the ____

superolaterally


lateral surface of the calcaneus

largest surface of the cuboid with an elongated posteromedial angle

plantar surface

peroneal sulcus

groove that runs parallel to the anterior border of the plantar surface of the cuboid. Peroneus longus runs in here

promontory of the cuboid

on plantar surface, it bounds the peroneal sulcus posteriorly

tuberosity of the cuboid

bulbous lateral end of the promontory

peroneal notch

deep notch on lateral surface of the cuboid that is continuous with the peroneal sulcus

calcaneal process of the cuboid
