Talus Overview

This tutorial provides a comprehensive overview of the talus bone, also known as the ankle bone. It covers the anatomy, including its three main parts: the head, neck, and body. The tutorial details the articulations of the talus with other bones, forming joints like the talocalcaneal navicular and talocrural joints. It also explores the bony landmarks and ligaments associated with the talus, emphasizing its role in ankle stability. Clinical notes highlight the implications of talus fractures, including potential vascular issues.

What is the shape of the talus bone?

• Pyramid-shaped

• Cube-shaped

• Snail-shaped

• Sphere-shaped

Which bones does the talus articulate with to form the talocrural joint?

• Tibia and fibula

• Cuboid and cuneiform

• Calcaneus and navicular

• Femur and patella

What is the function of the subtalar joint?

• Allows inversion and eversion

• Supports elbow extension

• Enables shoulder rotation

• Facilitates knee flexion

Which part of the talus is known for having a convex surface?

• Posterior process

• Head

• Neck

• Body

What is the sinus tarsi?

• A ligament in the knee

• A cavity in the ankle

• A bone in the wrist

• A muscle in the arm

Which ligament is also known as the medial collateral ligament?

• Calcaneal fibular ligament

• Posterior talofibular ligament

• Deltoid ligament

• Anterior talofibular ligament

What is the role of the anterior talofibular ligament?

• Connects the talus to the fibula anteriorly

• Connects the talus to the tibia posteriorly

• Connects the calcaneus to the fibula

• Connects the navicular to the talus

What can result from a displaced fracture of the talus neck?

• Enhanced ligament strength

• Avascular necrosis

• Increased blood supply

• Improved joint mobility

Which arteries are vulnerable to rupture in talus fractures?

• Femoral and radial

• Posterior tibial and dorsalis pedis

• Brachial and ulnar

• Carotid and subclavian

What is a common complication of undisplaced talus fractures?

• Vessel rupture

• Severe pain

• Joint dislocation

• Minimal complications
