What are the anatomical structure of talus?

The talus has been described as having three main components: head, neck, and body. It is an irregular saddle-shaped bone. The talar body has a curved smooth trochlear surface also termed the talar dome, which is covered with hyaline cartilage and convex from front to back.

Where is talus located?

The talus is a small bone that sits between the heel bone (calcaneus) and the two bones of the lower leg (the tibia and fibula). It has an irregular, humped shape like a turtle’s shell. The bones of the lower leg ride on top and around the sides to form the ankle joint.

What part of the body is the talus?

The talus is the bone that makes up the lower part of the ankle joint (the tibia and fibula make up the upper part). The ankle joint allows your foot to move up and down. The talus also sits above the heel bone (calcaneus). Together, the talus and calcaneus form the subtalar joint.

What structures are related to talus?

The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot. The talus has joints with the two bones of the lower leg, the tibia and thinner fibula….

Which bones does the talus articulate with?

The talus (plural: tali 4), also known as the astragalus 4, is a tarsal bone in the hindfoot that articulates with the tibia, fibula, calcaneus, and navicular bones.

What is the head of talus?

The talar head is the part that articulates with the navicular bone. On its inferior aspect, this is continuous with three articular facets that are separated by smooth ridges. There are anterior and middle facets which articulate with corresponding facets on the calcaneus.

Where does a talus fracture hurt?

Talus fracture causes significant ankle pain, difficulty bearing weight on the ankle, and swelling around the ankle joint. 3 These symptoms warrant going to the doctor right away.

What supports the head of the talus?

The talar head and body are connected by the talar neck, which is inclined downwards distally and medially.. The inferior surface of the talar neck has a deep groove, the sulcus tali, that passes obliquely forward and expands from medial to lateral.

What does talus mean in science?

Talus. An outward sloping and accumulated heap or mass of rock fragments of any size or shape (usually coarse and angular) derived from and lying at the base of a cliff or very steep, rocky slope, and formed chiefly by gravitational falling, rolling, or sliding.

Is the talus bone weight bearing?

position in skeletal systems. The talus (astragalus) articulates above with the bones of the lower leg to form the ankle joint. The other six tarsals, tightly bound together by ligaments below the talus, function as a strong weight-bearing platform.

Can you walk with a talus fracture?

You should be able to walk on it, but not without pain. Displaced. The pain, swelling, and tenderness are greater. You may not be able to put weight on the injured ankle.
