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] The favored idea is that the cuboid bone is forcefully everted while the calcaneus is inverted resulting in incongruity at the calcaneocuboid joint. [1]
The calcaneocuboid joint is conventionally described as among the least mobile joints in the human foot.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.
Treatment comprises early reduction of the dislocation, and frequently involves open reduction internal fixation to restore and stabilise the talonavicular joint. Open reduction and fusion of the calcaneocuboid joint is occasionally required.
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.
The intertarsal joint are the joints of the tarsal bones in the foot. There are six specific inter tarsal joints (articulations) in the human foot: Subtalar joint; Talocalcaneonavicular joint; Calcaneocuboid joint; Cuneonavicular joint; Cuboideonavicular joint; Intercuneiform joints
A CT scan is currently the imaging study of choice for evaluating calcaneal injury and has substituted conventional radiography in the classification of calcaneal fractures. [13] Axial and coronal views are obtained for proper visualization of the calcaneus, subtalar, calcaneocuboid and talonavicular joints.
The dorsal calcaneocuboid ligament (superior calcaneocuboid ligament) is a thin but broad fasciculus, which passes between the contiguous surfaces of the calcaneus and cuboid, on the dorsal surface of the joint.
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).
