Jones Fracture

Summary

  • A “Jones’ fracture” 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.
  • Activities that repetitively load the foot (for example sports with running) may lead to a Jones’ fracture.
  • Tend to occur in people that have a high arched foot shape or a leg shape that results in increased loading on the lateral aspect of the foot.
  • The fracture is believed to occur as a result of significant adduction force to the forefoot with the ankle in plantar flexion.

Diagnostic tips

  1. Pain and swelling distal to the styloid process.
  2. Difficulty walking.
  3. Difficulty bearing weight.
  4. History of pain prior the actual break.
  5. High arched feet.

Tests and Imaging

  1. History and physical examination of the feet.
  2. Plain x-rays of foot will identify a Jones’ fracture. (can be seen in area where more flexible bone at the base of the metatarsal meets the more rigid bone of the shaft of the metatarsal).

Immediate Treatment

  1. Advise non-weight bearing for 6-8 weeks (or more) until the fracture heals.
  2. Consider crutches.
  3. May prescribe protective boot.

Possible Referral

  1. Podiatry for immobilisation cam walker, footwear advice and orthoses following return to weightbearing.
  2. Foot and ankle surgery for internal fixation.
