CT Ankle & Hindfoot (Part 2) - Video Lesson

Hey everybody, welcome back. This lesson is about the ankle and hindfoot as seen in CT imaging. We'll be looking at sectional images starting in the coronal plane. This is a coronal reformation of the ankle and hindfoot. Starting in the center of the joint, we can see the three bones that form the ankle, the tibia, the fibula and the talus. The tibia is the larger and medial bone of the lower leg. It is the primary weight bearing bone of the lower leg. The fibula is the smaller and lateral bone of the lower leg. It bears very little weight, but it serves as an important point of muscle and ligament attachment and contributes to the stability of the ankle. The articulation between the tibia and fibula is called the tibiofibular joint, sometimes called the distal tibiofibular syndesmosis. The distal fibula forms this rounded projection called the lateral malleolus. This is the bony prominence on the lateral side of the ankle joint. The distal tibia forms a similar projection
