Iselin disease is a benign and self-limiting condition, defined as apophysitis of base of 5th metatarsal.

Epidemiology

It is most commonly seen in males with sport injuries and is often also seen in adolescents.

Pathology

It is due to repetitive traction of peroneus brevis tendon at the site of its attachment. Predisposing factors are jumping and running.

Radiographic features

Plain film

obliquely oriented small bony fleck at the base of 5th metatarsal which is best seen on oblique radiograph
apophyseal irregularity

Differential diagnosis

On imaging consider

normal apophysis
accessory ossicle (e.g. os vesalianum or os peroneum)
stress fracture
Jones fracture
