What Is the Cuneiform Bone?

The cuneiform bone, in human anatomy, may mean any of three bones located in either the top or middle of the foot. The three bones are the medial cuneiform bone, the lateral cuneiform bone, and the intermediate cuneiform bone. The arching form of the foot is partially due to the structure of the cuneiform bone. The cuneiform bones connect the navicular and cuboid bones to the metatarsus bones. Cuneiform writing uses wedge shapes, because of this shape similarity the same name was coined for the cuneiform bone.

The medial cuneiform is called such because of its connection to the first metetarsal, which connects to the first phalanges, which then connects to the big toe. The intermediate, also middle, cuneiform is shaped like a wedge and is in line with the second toe. The interior, also lateral, cuneiform is in line with the bones of the third toe. A large number of strong ligaments hold each of the three above-mentioned bones in place.

Ligament strain of bone injure may lead to feelings of pain around the cuneiform bones. Let alone injury to these bones, like with most other bones, can lead to deformity and severe pain, may in extreme cases cause loss of mobility. Since even sprains and simple trauma will most likely cause the area around the injury to become enflamed making it difficult to readily diagnose any injury to this area of the foot, with out a proper CT scan or other more advanced medical imaging technology. In the event of pain or suspected injury to the cuneiform bones immediately consult with a physician.
