A Jones fracture is a broken bone in a specific part of the fifth metatarsal of the foot between the base and middle part [8] that is known for its high rate of delayed healing or nonunion. [4] It results in pain near the midportion of the foot on the outside. [2] There may also be bruising and difficulty walking. [3] Onset is generally sudden. [4]
The fifth metatarsal bone is a long bone in the foot, and is palpable along the distal outer edges of the feet. 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.
Proximal fractures of 5th metatarsal. The tuberosity avulsion fracture (also known as pseudo-Jones fracture or dancer's fracture [2] is a common fracture of the fifth metatarsal (the bone on the outside edge of the foot extending to the little toe). [3] This fracture is likely caused by the lateral band of the plantar aponeurosis (tendon). [4]

Type 1: The head of the 5th metatarsal is thickened and enlarged. Type 2: A 5th metatarsal with an increased lateral curve and a normal fourth and fifth inter-metatarsal angle. Type 3: Has the greatest lateral angular disposition of the 5th metatarsal compared to the 4th metatarsal, this phenomenon increases the 4th and 5th inter-metatarsal angles.
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 dorsal ligaments are strong, flat bands.. The first metatarsal is joined to the first cuneiform by a broad, thin band; the second has three, one from each cuneiform bone; the third has one from the third cuneiform; the fourth has one from the third cuneiform and one from the cuboid; and the fifth, one from the cuboid.
The lateral arch is composed of the calcaneus, the cuboid, and the fourth and fifth metatarsals. [1] Two notable features of this arch are its solidity and its slight elevation. Two strong ligaments, the long plantar and the plantar calcaneocuboid, together with the extensor tendons and the short muscles of the little toe, preserve its ...
