It is distinct in appearance because of its large size with a cuboidal body. Read more. The flexor digitorum brevis muscle is located in the foot. The lateral cuneiform is a wedge-shaped bone. The lateral cuneiform bone articulates with four bones: the intermediate cuneiform, cuboid, navicular, and the third metatarsal bone. It is smaller than the medial … The talus (astragalus in animals) is the 2nd largest tarsal and sits atop of the calcaneus, between the tibia and the fibula. Still, like the other toes, it assists…. Experimentally Generated Footprints in Sand: Analysis and Consequences for the Interpretation of Fossil and Forensic Footprints. Gosling, J. These are the medial, middle, and lateral cuneiforms. The lateral cuneiform is similar to its intermediate cuneiform brother in that it has a rough rectangular wedge. Commonly, a small sprain can result in a full avulsion as the second metatarsal becomes unstable due to the laxity of the LisFranc’s ligament. Brothwell, D. R. 1981. Cuboid Syndrome. There is a bit of swelling around the cuneiform. The lateral cuneiform is located between two other cuneiform bones (all of which are wedge-shaped) and is of intermediate size. This is a common feature in crowded burial grounds, and care must be taken when excavating and assigning individual skeletal elements to specific individual skeleton’s (Brothwell 1981). Jarmey, C. 2003. Two muscles - tibialis anterior and peroneus longus - insert at the medial cuneiform bone. Bones of the right foot. Note the orientation and sequential laying of supine burials, and how the lower portion of the legs have been covered or destroyed by other burials.

The cuboid bone articulates anteriorly with the fourth and fifth metatarsals to form the tarsometatarsal joint.The cuboid also articulates posteriorly with the heel bone (calcaneus) to form the calcaneocuboid or CC joint. The lateral and medial articular surfaces of adjacent cuneiform bones articulate with each other, but in the case of the lateral cuneiform - with the cuboid bone. 2008: 284).

The foot, or Pes, forms the distal terminus of the leg. The lateral, or interior, cuneiform is aligned with the bones of the third toe. It also receives a slip of the tendon of the tibialis posterior on the plantar surface, which again enables the bone to play an important role in forming the medial foot arch. The talocrural (ankle) joint, the articulation between the leg and the foot, forms an important part of the stability of the foot, one of the main differences behind the pes and the manus (the wrist is extremely movable and flexible in comparison to the ankle). Bioarchaeology: Interpreting Behaviour From The Human Skeleton. The interosseous ligament marries the non-articular surfaces to the other cuneiforms.
