posterior talofibular ligament; The posterior talofibular ligament runs horizontally between the neck of the talus and the medial side of lateral malleolus calcaneofibular ligament; The calcaneofibular ligament is attached on the posteromedial side of lateral malleolus and descends posteroinferiorly below to a lateral side of the calcaneus.
On the front of the ankle the sheath for the Tibialis anterior extends from the upper margin of the transverse crural ligament to the interval between the diverging limbs of the cruciate ligament; those for the Extensor digitorum longus and Extensor hallucis longus reach upward to just above the level of the tips of the malleoli, the former being the higher.
The inferior extensor retinaculum of the foot (cruciate crural ligament, lower part of anterior annular ligament) is a Y-shaped band placed in front of the ankle-joint, the stem of the Y being attached laterally to the upper surface of the calcaneus, in front of the depression for the interosseous talocalcaneal ligament; it is directed medialward as a double layer, one lamina passing in front ...
The deltoid ligament (or medial ligament of talocrural joint) is a strong, flat, triangular band, attached, above, to the apex and anterior and posterior borders of the medial malleolus. The deltoid ligament supports the ankle joint and also resists excessive eversion of the foot. [1] The deltoid ligament is composed of 4 fibers:
The posterior border is broad and presents the shallow malleolar sulcus, for the passage of the tendons of the peronæi longus and brevis. The summit is rounded and gives attachment to the calcaneofibular ligament. A major structure that is located between the lateral malleolus and the Achilles tendon is the sural nerve.
The ankle, the talocrural region [1] or the jumping bone (informal) is the area where the foot and the leg meet. [2] The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. [3] [4] [5] The movements produced at this joint are dorsiflexion and plantarflexion of the ...
The calcaneofibular ligament is a narrow, rounded cord, running from the tip of the lateral malleolus of the fibula downward and slightly backward to a tubercle on the lateral surface of the calcaneus. It is part of the lateral collateral ligament, which opposes the hyperinversion of the subtalar joint, as in a common type of ankle sprain. [1]
The ligament is strengthened medially by blending with the deltoid ligament of the ankle joint, and is supported inferiorly by the tendon of the tibialis posterior, which is spread out in a fanshaped insertion and prevents undue tension of the ligament or such an amount of stretching as would permanently elongate it.
