Ankle joint anatomy in 3D

The ankle joint (talocrural joint) is formed where the lower ends of the tibia and fibula grip the top of the talus from both sides. The bump on the inside of the ankle, the medial malleolus, is the end of the tibia; the one on the outside, the lateral malleolus, is the end of the fibula. Body weight passes through this joint from the leg into the foot.
