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.
Cuboid syndrome may develop through either a single traumatic event such as an ankle sprain or insidiously with repetitive strain over time. [1] The exact etiology of cuboid syndrome remains unclear but many ideas have been proposed. Such ideas include excessive pronation of the foot, overuse injury, and inversion ankle sprains. [1]
In the human body, the tarsus (pl.: tarsi) is a cluster of seven articulating bones in each foot situated between the lower end of the tibia and the fibula of the lower leg and the metatarsus. It is made up of the midfoot (cuboid, medial, intermediate, and lateral cuneiform, and navicular) and hindfoot (talus and calcaneus).
A Lisfranc injury, also known as Lisfranc fracture, is an injury of the foot in which one or more of the metatarsal bones are displaced from the tarsus. [1] [2]The injury is named after Jacques Lisfranc de St. Martin, a French surgeon and gynecologist who noticed this fracture pattern amongst cavalrymen in 1815, after the War of the Sixth Coalition.
The articular surfaces of the two bones are relatively flat with some irregular undulations, which seem to suggest movement limited to a single rotation and some translation. However, the cuboid rotates as much as 25° about an oblique axis during inversion-eversion in a movement that could be called involution. [3]
While these medial and lateral arches may be readily demonstrated as the component antero-posterior arches of the foot, the fundamental longitudinal arch is contributed to by both, and consists of the calcaneus, cuboid, third cuneiform, and third metatarsal: all the other bones of the foot may be removed without destroying this arch. [1]
The foot is usually dislocated medially (80%) and superiorly, which occurs when the foot is plantar flexed and inverted. Lateral displacement occurs during eversion injuries. Associated fractures of calcaneus, cuboid and navicular are frequent. Open fractures occur in a small percentage.
The transverse tarsal joint or midtarsal joint or Chopart's joint is formed by the articulation of the calcaneus with the cuboid (the calcaneocuboid joint), and the articulation of the talus with the navicular (the talocalcaneonavicular joint).
