Iselin disease primarily affects which bone structure?

• A. Fifth metatarsal base
• B. First metatarsal head
• C. Calcaneus
• D. Talus

Answer: (A)

Iselin disease is a condition that primarily affects the base of the fifth metatarsal. This disorder occurs due to a traction apophysitis at the growth plate of the fifth metatarsal, often seen in adolescents who are active in sports. The condition is characterized by pain and tenderness in the area where the tendon of the peroneus brevis muscle attaches. This particular bone structure is most susceptible to stress and loading, making it the critical area impacted by Iselin disease. The other options, such as the first metatarsal head, calcaneus, and talus, are not the primary sites affected by this condition, as Iselin disease is specifically linked to the traction forces at the base of the fifth metatarsal during periods of activity or growth spurts in young athletes.
