In the foot, there are three cuneiform bones. They include the intermediate, lateral, and mediate designations. The intermediate cuneiform bone is located between its two counterparts, and it articulates with the second metatarsal, which is jointed to the phalanges of the second toe. Collectively, the tarsal bones make up half of the foot and the entirety of the ankle. The smallness of each bone, intermediate cuneiform included, allows for flexibility in the foot and the ankle, which joints with the tibia and fibia bone of the lower leg. This flexibility is a fundamental necessity allowing a person to use their foot for walking or any other types of bipedal movements. The feet bare the entire weight of the body, and since walking requires constant impact with the ground, the tarsal bones of the feet are prone to fracture. Should the intermediate cuneiform break, the whole foot would need to be immobilized as a result. The multiple points of articulation could cause movement that may complicate healing.
