The cuneiforms make up three bones in the midfoot. These bones interlock with each other and are the bridge between the navicular and the metatarsals. The importance of these bones lies in their solid structure and the fact that they create a very stable medial column of the foot. This stability is extremely important in walking and running, as it allows muscles around the ankle and foot strength to propel the body forward.
Cuneiform fractures are very rare in isolation and are most often seen in the context of Lisfranc injuries of the foot. These are commonly-missed ligamentous injury that can also occur with fractures. As in Mr Biden’s case, it is important to look carefully for them with detailed cross-sectional imaging of the foot (CT or MRI scanning) since if missed, they can lead to mal-alignment of the midfoot bones and subsequent disabling arthritis.
