- 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.
- Pain and swelling distal to the styloid process.
- Difficulty walking.
- Difficulty bearing weight.
- History of pain prior the actual break.
- High arched feet.
Tests and Imaging
- History and physical examination of the feet.
- 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).
- Advise non-weight bearing for 6-8 weeks (or more) until the fracture heals.
- Consider crutches.
- May prescribe protective boot.
- Podiatry for immobilisation cam walker, footwear advice and orthoses following return to weightbearing.
- Foot and ankle surgery for internal fixation.
