The talus (/ ˈ t eɪ l ə s /; Latin for ankle [1] or ankle bone; [2] pl.: tali), talus bone, astragalus (/ ə ˈ s t r æ ɡ ə l ə s /), or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot. [3]
The bones of the tarsus are the rear most bones in the adjacent diagram: calcaneus, talus, navicular, cuboid, medial cuneiform, intermediate cuneiform and lateral cuneiform bones. [9] These bones create the two major foot joints – the subtalar and midtarsal joints – that allow complex motions to occur in the feet. These motions are ...
The tarsal tunnel is delineated by bone on the inside and the flexor retinaculum on the outside. People with TTS typically complain of numbness in the foot radiating to the big toe and the first three toes, pain , burning, electrical sensations, and tingling over the base of the foot and the heel.

The talus bone or ankle bone is connected superiorly to the two bones of the lower leg, the tibia and fibula, to form the ankle joint or talocrural joint; inferiorly, at the subtalar joint, to the calcaneus or heel bone. Together, the talus and calcaneus form the hindfoot. [1] The five irregular bones of the midfoot—the cuboid, navicular, and ...
The anatomy and shape of a person's longitudinal and transverse arch can dictate the types of injuries to which that person is susceptible. The height of a person's arch is determined by the height of the navicular bone. Collapse of the longitudinal arches results in what is known as flat feet. [5]

The main ligament of the joint is the interosseous talocalcaneal ligament, a thick, strong band of two partially joined fibers that bind the talus and calcaneus. It runs through the sinus tarsi, a canal between the articulations of the two bones. There are four additional ligaments that form weaker connections between the talus and calcaneus.
Dysfunction of the superior cluneal nerves lead to many different neuropathic symptoms such as burning pain, numbness, tingling, and dysesthesia around the low back and upper gluteal area. The most common symptoms are localized unilateral low back pain, though up to anywhere between 40 and 82% of patients may complain of leg symptoms – pain ...
