There are three proximal tarsals, the tibiale, intermedium, and fibulare, named for their points of articulation with the bones of the lower limb. These are followed by a second row of four bones, referred to as the centralia (singular: centrale), and then a row of five distal tarsals, each articulating with a single metatarsal. In the great ...
The dorsal ligaments are strong, flat bands.. The first metatarsal is joined to the first cuneiform by a broad, thin band; the second has three, one from each cuneiform bone; the third has one from the third cuneiform; the fourth has one from the third cuneiform and one from the cuboid; and the fifth, one from the cuboid.
Os trigonum on X-ray. Though irregular in shape, the talus can be subdivided into three parts. Facing anteriorly, the head carries the articulate surface of the navicular bone, and the neck, the roughened area between the body and the head, has small vascular channels.
Accessory bones amidst tarsals. Three proximal bones. Humans hold all three in their hands. In the foot, the middle proximal appears in 5–15% of people as an os trigonum and can be involved in foot pain. [1] Centrale or os centrale, is on the medial side.
Definition Etymologic memory aid; apophysis: Any of various processes or protuberances on a bone. apo-+ physis, "outward from the growth part; outgrowth" diaphysis: The long, relatively straight main body of a long bone; region of primary ossification. Also known as the shaft. dia-+ physis, "between the growth parts" epiphysis
Its proximal articular surface is large and kidney-shaped; its circumference is grooved, for the tarsometatarsal ligaments, and medially gives insertion to part of the tendon of the tibialis anterior. The body of the bone is strong, and of well-marked prismoid form.
There are three cuneiform bones: The medial cuneiform (also known as first cuneiform) is the largest of the cuneiforms.It is situated at the medial side of the foot, anterior to the navicular bone and posterior to the base of the first metatarsal.
The five metatarsals are dorsal convex long bones consisting of a shaft or body, a base (), and a head (). [3] The body is prismoid in form, tapers gradually from the tarsal to the phalangeal extremity, and is curved longitudinally, so as to be concave below, slightly convex above.
