Instability of the Tibiotalar Joint

The skeletal framework of the ankle joint is formed by the tibiotalar articulation and the distal tibiofibular syndesmosis. For correct clinical recognition of ankle lesions, one must remember that the hindfoot is an extremely integrated structure. The central element of this structure is the talus, which closely related with the tibia, calcaneus, cuboid and navicular. These skeletal components are connected by the peritalar ligamentous system, supported by the musculotendinous structures that pass around the talus.
