Iselin disease

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

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

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