Prognosis
If a Jones fracture fails to unite (malunion or non union), which is a common problem with these fractures, it can become a chronic condition. If this is the case, podiatrists will likely recommend that the patient spend more time in a cast, up to twenty weeks.
For several reasons, a Jones fracture often does not heal. The diaphyseal bone, where the fracture occurs, is an area of poor blood supply. In medical terms, it is a watershed area between two blood supplies. This makes healing difficult. In addition, there are various tendons, including the peroneus brevis and fibularis tertius, and two small muscles attached to the bone. These may pull the fracture apart and prevent healing.
