Presentation
Trauma.
Patient Data
Two fracture lines are seen in the proximal of the 5th metatarsal, better seen in the oblique view. One is transverse and extends to the inter-metatarsal joint inferring a Jones fracture. The other is more proximal and extends obliquely to the metatarso-cuboid joint, consistent with avulsion or pseudo-Jones fracture.
In addition, mild degenerative changes are seen in the mid-tarsal and first MTP joints. Hallux valgus is also observed.
Case Discussion
The proximal 5th metatarsal is the site of a number of fractures and variants which mimic fractures, and it's important to differentiate. In contrast to pseudo-Jones (avulsion) fractures, Jones fractures are prone to non-union and almost always take longer than two months to heal.
