Jones fracture

A Jones fracture is an extra-articular fracture at the base of the fifth metatarsal bone.

It is a transverse fracture at the base of the fifth metatarsal, 1.5 to 3 cm distal to the proximal tuberosity at the metadiaphyseal junction, without distal extension. 

The fracture is believed to occur as a result of significant adduction force to the forefoot with the ankle in plantar flexion 5.

Jones fracture is located at the metadiaphyseal junction, approximately 2 cm (1.5-3 cm) from the tip of the 5th metatarsal, and has a predominantly horizontal course. It should not extend distally, nor should it extend to involve the articular surfaces.

In contrast to avulsion fractures, Jones fractures are prone to non-union (with rates as high as 30-50%) and almost always take longer than two months to heal 2

As displacement of the fracture can be increased with persistent weight bearing, immobilization is important as part of the initial therapy, with a non-weight bearing cast for 6-8 weeks.  Indications for non-operative management include undisplaced fractures and fractures in patients with limited activity (i.e. recreational athletes) 7.

Operative management is indicated in patients that are elite or competitive athletes or in non-operatively managed fractures when delayed union has occurred 7,8. Management includes either intra-medullary screw fixation or open reduction and internal fixation (ORIF is also the main management option as a salvage procedure when there is non-union following screw fixation) 7. The outcomes are similar with almost 100% union rates 7

Internal fixation and even bone grafting may be required in cases of non-union, or where the fracture is significantly displaced. 

It was first described by Sir Robert Jones (1857-1933), Welsh orthopedic surgeon, in 1902 3,6.

A number of fractures occur at the base of the 5th metatarsal (see fractures of the proximal fifth metatarsal) as well as entities which mimic fractures. These include:
