Proximal articular fractures of the 5th metatarsal (Jones fracture)


These fractures go into the base of the 4th and 5th metatarsal articular surface.

This fracture is not a simple avulsion proximally or distal shaft fracture.

These fractures are often referred to as Jones fractures.

87 D400 Definition

Mechanism of injury

Inversion ankle or foot injury, often landing from a jump or rolling foot on uneven ground. This fracture can also be the result of a stress fracture that acutely occurs and may displace.

The peroneus brevis is eccentrically loaded, and it pulls on the base of the metatarsal, creating a tension failure fracture.


AP, lateral, and oblique x-rays confirm the diagnosis.


Inherent stability

This fracture occurs in the relatively poorly vascularized metaphyseal bone between the insertions of the peroneus tertius and the peroneus brevis tendons, which combine to produce a deforming force, as illustrated. This fracture is otherwise known as “march fracture”. The poor blood supply and loading of the fracture by continuing muscle force even without weight-bearing increase the risk of delayed healing or non-union.

The Jones fracture is an extraarticular fracture.

Associated injuries

There are typically no associated injuries with these fractures.
