What bones form the ankle joint?

The ankle joint is formed by the lower ends of the tibia and fibula (creating a mortise) and the body of the talus bone.

What are the primary movements of the ankle joint?

The ankle allows two main movements: dorsiflexion (lifting the foot up) and plantar flexion (pointing the foot down).

Which ligaments are most commonly injured in an ankle sprain?

Ankle sprains often involve the anterior talofibular ligament (part of the lateral ligament complex), typically due to inversion injuries.

What is the most stable position of the ankle joint?

The ankle is most stable during dorsiflexion (the close-packed position), where the mortise grips the talus tightly, reducing risk of injury.

What nerves supply the ankle joint?

The ankle joint is innervated by the deep peroneal nerve anteriorly and the tibial nerve posteriorly.

What is a Pott's fracture?

A Pott's fracture is a trimalleolar fracture involving a spiral fracture of the lateral malleolus, a transverse fracture of the medial malleolus, and a fracture of the posterior tibial margin.

What structures are found anterior to the ankle joint?

Anteriorly, from medial to lateral, key structures include tibialis anterior, extensor hallucis longus, anterior tibial artery, deep peroneal nerve, extensor digitorum longus, and peroneus tertius.
