Can a fracture in the talus cause a person to walk?
Any injury to this critical bone may hamper the movements of the ankle and foot. A major fracture in the bone can cause serious impediment to a person’s ability to walk or stand.

Structure and Anatomy
As mentioned, this is a short, irregular, saddle-shaped bone, which can be divided into three parts: head, neck, and body. The talus also bears several articular surfaces and two protuberances on the back and side, the posterior and lateral processes. It is wider in front than the back.
What is the body of the talus?
Body. Talus in red, showing surrounding bones. The body of the talus comprises most of the volume of the talus bone (ankle bone). It presents with five surfaces; a superior, inferior, medial, lateral and a posterior: The superior surface of the body presents, behind, a smooth trochlear surface, the trochlea, for articulation with the tibia.
Where does the talus come from?
The talus apparently derives from the fusion of three separate bones in the feet of primitive amphibians; the tibiale, articulating with tibia, the intermedium, between the bases of the tibia and fibula, and the fourth centrale, lying in the mid-part of the tarsus. These bones are still partially separate in modern amphibians, which therefore do not have a true talus. The talus forms a considerably more flexible joint in mammals than it does in reptiles. This reaches its greatest extent in artiodactyls, where the distal surface of the bone has a smooth keel to allow greater freedom of movement of the foot, and thus increase running speed.
What bones are in the foot?
These leg bones have two prominences (the lateral and medial malleoli) that articulate with the talus. At the foot end, within the tarsus, the talus articulates with the calcaneus (heel bone) below, and with the curved navicular bone in front; together, these foot articulations form the ball-and-socket -shaped talocalcaneonavicular joint.
What is the head of the ankle?
