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 tibial nerve, posterior tibial artery, posterior tibial vein, and flexor tendons travel in a bundle along this pathway through the tarsal tunnel, in the following order from anteromedial to posterolateral: Tibialis posterior tendon. [2] Flexor digitorum longus tendon. [2] Posterior tibial artery. [2] Posterior tibial vein. [1] Tibial nerve. [2]
Sagittal magnetic resonance images of ankle region: psoriatic arthritis. (a) Short tau inversion recovery (STIR) image, showing high signal intensity at the Achilles tendon insertion (enthesitis, thick arrow) and in the synovium of the ankle joint (synovitis, long thin arrow). Bone marrow oedema is seen at the tendon insertion (short thin arrow ...
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 ...
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 incision is made behind the ankle bone and then down towards but not as far as the bottom of foot. The posterior tibial nerve is identified above the ankle. It is separated from the accompanying artery and vein and then followed into the tunnel. The nerves are released. Cysts or other space-occupying problems may be corrected at this time.
The tendons are inserted in the following manner: each receives a fibrous expansion from the interossei and lumbricals, and then spreads out into a broad aponeurosis, which covers the dorsal surface of the first phalanx: this aponeurosis, at the articulation of the first with the second phalanx, divides into three slips — an intermediate ...
The muscle ends in a long tendon, which runs behind the lateral malleolus of the ankle in a groove that it shares with the tendon of the fibularis brevis; the groove is converted into a canal by the superior fibular retinaculum, and the tendons in it are contained in a common mucous sheath. [2]
