Pseudo-Jones fracture


Fractures of the fifth metatarsal are the most common of all foot fractures.1 Emergency physicians must understand the different types of fractures as management and prognosis differs widely.

The inter-metatarsal joint between the bases of the fourth and fifth metatarsals is a key landmark (identified by black X in image above) for classifying proximal fifth metatarsal fractures. Tuberosity (styloid) fractures occur proximal to this joint while fractures of the metaphyseal-diaphyseal junction (Jones fractures) extend toward this joint.2

The patient in this case has a proximal tuberosity avulsion fracture, also known as Pseudo-Jones fracture. The fracture here extends into the cubo-metatarsal joint and is clearly proximal to the inter-metatarsal joint. Treatment of a Pseudo-Jones fracture involves symptomatic care and weight bearing as tolerated with most fractures healing in three to six weeks.2

This is a Jones’ Fracture. In 1902, Sir Robert Jones first described a specific fifth metatarsal fracture at ‘the proximal 3/4 segment of the shaft distal to the styloid by indirect violence of his own foot and that of four other patients.’ The Jones’ fracture has since been defined as:1

A transverse fracture at the metaphyseal/diaphyseal junction without distal extension beyond the fourth to fifth intermetatarsal articulation.

The Jones fracture is specially recognized by emergency physicians because it:3

  • Has high likelihood of delayed union or non-union
  • Often requires surgical intervention
  • Requires orthopedics consultation
