Trauma.

Patient Data

Age: 30 years
Gender: Male
x-ray

A transverse fracture line is noted in the base of the 5th metatarsal that extends into the intermetatarsal joint inferring Jones fracture. In addition, another fine fracture line is observed in the proximal of the 5th metatarsal, extending into the metatarsocuboid joint suggesting pseudo-Jones (avulsion) fracture.

Case Discussion

Relative to pseudo-Jones fractures, Jones fractures are particularly prone to non-union and therefore, immobilization is important as part of the initial therapy.

The proximal 5th metatarsal is the site of some fractures and variants which mimic fractures.
