Case Discussion
Jones fractures are basal extra-articular fractures of the 5th metatarsal. They are usually caused by the forced adduction of the forefoot.
Basal fractures of the 5th metatarsal can be divided into three zones:
- zone 1: avulsion fracture (pseudo-Jones fracture)
- zone 2: extra-articular fracture at the proximal metaphyseal-diaphyseal junction (true Jones fracture)
- zone 3: proximal shaft fracture (usually stress fractures)
