Iselin's disease commonly affects which populations?

• A. Girls 9-11 years
• B. Boys 11-14 years
• C. Both A and B
• D. Adults

Answer: (C)

Iselin’s disease is a traction apophysitis at the base of the fifth metatarsal that occurs in growing children and adolescents. It happens when repetitive pulling forces from the peroneus brevis act on an open growth plate during growth spurts. Because the growth plate remains open through late childhood into early adolescence, this condition commonly affects both boys and girls in the 9–14 year age range. Adults, with closed physes, are not typically affected in the same way. Therefore, the population described as both a girl around 9–11 and a boy around 11–14 fits the common pattern.
