The base or posterior extremity is wedge-shaped, articulating proximally with the tarsal bones, and by its sides with the contiguous metatarsal bones: its dorsal and plantar surfaces are rough for the attachment of ligaments. The head or distal extremity presents a convex articular surface, oblong from above downward, and extending farther ...

The tarsometatarsal joints involve the first, second and third cuneiform bones, the cuboid bone and the metatarsal bones. The eponym of Lisfranc joint is 18th–19th-century surgeon and gynecologist Jacques Lisfranc de St. Martin. [1]
An avulsion fracture at the base of the fifth metatarsal is sometimes called a "dancer's fracture" or a "pseudo Jones fracture", and usually responds readily to non-operative treatment. [18] The X-ray appearance of the developmental "apophysis" in this area may have some resemblance of a fracture, but is not a fracture; it is the secondary ...
The fourth metatarsal is analogous to the fourth metacarpal bone in the hand [1] 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.
In runners, march fracture occurs most often in the metatarsal neck, while in dancers it occurs in the proximal shaft. In ballet dancers, fracture mostly occurs at the base of the second metatarsal and at Lisfranc joints. This fracture always occurs following a prolonged stress or weight bearing, and the history of direct trauma is very rare.
It is the second smallest of the five metatarsal bones. The fifth metatarsal is analogous to the fifth metacarpal bone in the hand. [1] As with the four other metatarsal bones it can be divided into three parts; a 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 ...
The base or posterior extremity is wedge-shaped. [1] The third metatarsal bone articulates proximally, by means of a triangular smooth surface, with the third cuneiform; medially, by two facets, with the second metatarsal; and laterally, by a single facet, with the fourth metatarsal. This last facet is situated at the dorsal angle of the base.
