Under the talus, cuboid, navicular behind the couple. And the main bone of the foot is from a point of view of the static and dynamic. Static: because it receives 50% of the body weight and also because the arc and the outer arc ending on the rear inner and outer tuberosity of the calcaneus. Dynamic because it conditions the physiology of the forefoot. the calcaneus UPPER SIDE An anterior segment that presents 2 articular surfaces that correspond to the talus: a facet anterior inner concave (convex talus) and a posterior facet outer convex (concave talus). Between the 2 sides, the groove of the heel area of insertion of the leg. Interosseous. UNDERSIDE: From behind forward is concave, and convex transversely. It has three tuberosity, one front and one rear. The tuberosity is anterior insertion of the plantar ligament calcaneocuboid cuboideo. The posterior tuberosity has 2 processes: the medial adductor hallux gives insertion to the flexor digitorum brevis and the square foot; the side gives insertion to the abductor muscles of the 5th finger and the square foot. EXTERNAL SURFACE: presents the tubercle which gives insertion to the peroneal muscles (also called process trochlear), over which passes the short lateral peroneal and above passes along the lateral peroneal Later in this we have a prominent tubercle which gives insertion to the calcaneal-fibular ligament (ligament external beam middle compartment). INSIDE: We observe the calcaneal shower, which runs from the posterior tuberosity substentaculum such internal. Just below the sustentaculum such, there is a shower flowing with the flexor digitorum longus and the flexor under this right toe. These muscles support the internal arc, (in case of fall of this arc may have a predisposition to hallux valgus) Leg. Fibular-calcaneal, medium beam of the fund outside of the ankle; Leg. Deltoid, the beam surface of the inner compartment of the ankle. Leg. talocalcaneal rear which is the continuation of the
