Metatarsals are part of the bones of the mid-foot and are tubular in shape. They are named by numbers and start from the medial side onward. The medial side is the same side as the big toe. They are called the first metatarsal, second metatarsal, third metatarsal, fourth metatarsal, and the fifth metatarsal. The first metatarsal is the strongest of the collection. These bones are found between the phalanges of the toes and the tarsal bones. Each bone's base will move with at least one of the tarsal bones where the tarsometatarsal joint is located. The metatarsal bones are connected to the bones of the toe, or phalanges, at the knuckle of the toe, or metatarsophatangeal joint. Metatarsals are convex in shape, are long bones, and give the foot its arch. They work with ligaments and tendons to provide movement in the foot. They can become fractured, strained, or inflamed from misuse or overuse. Immobilization of the foot can help heal metatarsal breaks and sprains.
