The ankle joint (Figure 17.9, Figure 17.10) is the articulation between the talus, medial malleolus of the tibia, and lateral malleolus of the fibula. The anterior tibiofibular ligament and posterior tibiofibular ligament hold the distal ends of the tibia and fibula together at their articulation with the talus. The tibia is the weight-bearing bone of the leg, however, integrity of both the malleoli is essential for stability of the ankle.

The articular capsule of the ankle is thin anteriorly and posteriorly, but it has well defined medial and lateral thickenings or ligaments. The medial ligament of the ankle is called the deltoid ligament [posterior view]. It arises from the medial malleolus and inserts by four rather indistinct slips into the navicular bone, anterior part of the
talus, sustentaculum tali of the calcaneus, and the posterior part of the talus.
