rdf:langString The fourth metatarsal bone is a long bone in the foot. It is smaller in size than the third metatarsal bone and is the third longest (and smallest) of the five metatarsal bones. The fourth metatarsal is analogous to the fourth metacarpal bone in the hand As the four other metatarsals 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 toes. The narrowed part in the middle is referred to as the body or shaft of the bone. The bone is somewhat flatten giving it two surfaces; the plantar (towards the sole of the foot) and the dorsal side (the area facing upwards while standing). These surfaces are rough for the attachment of ligaments. The bone is curved longitudinally, so as to be concave below, slightly convex above. The base or posterior extremity is wedge-shaped. The base presents an oblique quadrilateral surface for articulation with the cuboid; a smooth facet on the medial side, divided by a ridge into an anterior portion for articulation with the third metatarsal, and a posterior portion for articulation with the third cuneiform; on the lateral side a single facet, for articulation with the fifth metatarsal. The head or anterior extremity articulates with the fourth proximal phalanx, the first bone in the fourth toe.
