Structure

Like the four other metatarsal bones, it can be divided into three parts: base, body and head. The base is the part closest to the ankle and the head is closest to the big toe. The narrowed part in the middle is referred to as the body of the bone. The bone is somewhat flattened, giving it two sides: the plantar (towards the

Each of these lateral articular surfaces is divided into two by a vertical ridge: the two anterior facets articulate with the third metatarsal and the two posterior (sometimes continuous) with the lateral cuneiform. A fifth facet is occasionally present for articulation with the first metatarsal; it is
