FOOT PAIN? YOU MIGHT HAVE A FRACTURE
Are you experiencing pain and swelling on the outside of your foot? Are you having difficulty walking? You may have a stress fracture, commonly known as Jones Fracture. This is a repetitive stress type injury commonly seen with runners.
A Jones Fracture is a stress fracture of the 5th Metatarsal at the metaphyseal-diaphyseal junction. They are often the result of repetitive stress built up over time. These fractures can be slow to heal. There is a high incidence of non-union due to poor blood supply in this area. This is different from an avulsion fracture (Dancer’s Fracture) where the insertion of the Peroneus Brevis pulls the bone or a fracture of the distal metatarsal.
Mechanism of Injury:
This is an overuse, repetitive stress type of injury. Injury occurs with a repetitive load applied under the metatarsal head over a relatively short time such as in running.
Increased loading of the lateral foot possibly due to alignment of the lower extremity
Pain and swelling in the lateral foot
Treatment is Variable:
Bony callus formation is visable on x-ray at 6-8 weeks post-injury. However, 1/3 of all Jones fractures end in non-union. Treatment options are as follows:
Weight Bearing in a Cast/Boot: 6-8 weeks in a cast or boot but able to put weight on it
Non-weight Bearing: 6-8 weeks in a cast or boot without putting weight through the foot. 14-15 weeks ‘til return to activities
Operative: Shorter times to union and quicker return to sport. This is typical of the younger and athletic population. 4-6 weeks non-weight bearing with a return to sport around 8 weeks. This is also the choice if non-operative treatment fails or the fracture is displaced.
