Ankle joint

This tutorial covers the anatomy of the ankle joint, including its bones, articulations, and ligaments. It explains the roles of the tibia, fibula, talus, calcaneus, and navicular bones, and describes the ankle joint proper and subtalar joint. The video also details the ligaments that stabilize these joints and discusses common clinical issues like ankle sprains.

What is the primary function of the ankle joint?

• To connect the leg to the foot

• To support the knee joint

• To provide flexibility to the toes

• To stabilize the hip joint

Which bone is commonly known as the shin bone?

• Fibula

• Tibia

• Calcaneus

• Talus

What is the role of the talus in the ankle joint?

• It forms the heel of the foot

• It connects the tibia and fibula

• It supports the arch of the foot

• It articulates with the ankle mortise

Which bone serves as an attachment site for ligaments but is not directly involved in the ankle joint?

• Fibula

• Tibia

• Navicular

• Talus

Which movement is NOT allowed by the ankle joint proper?

• Dorsiflexion

• Eversion

• Plantar flexion

• Inversion

What is the function of the subtalar joint?

• To stabilize the knee joint

• To enable inversion and eversion

• To allow dorsiflexion and plantar flexion

• To support the arch of the foot

Which ligament is part of the tibial collateral ligament group?

• Lateral talocalcaneal ligament

• Calcaneofibular ligament

• Tibial navicular ligament

• Anterior talofibular ligament

What is the primary role of the fibular collateral ligaments?

• To support the medial side of the ankle

• To stabilize the subtalar joint

• To connect the tibia to the navicular bone

• To support the lateral side of the ankle

Which ligament is most commonly injured in an ankle sprain?

• Tibial calcaneal ligament

• Anterior talofibular ligament

• Posterior tibiotalar ligament

• Interosseous talocalcaneal ligament

What typically causes an ankle sprain?

• Over dorsiflexion of the foot

• Over eversion of the foot

• Over inversion of the foot

• Over plantar flexion of the foot
