What is the primary cause of Apophysitis of the fifth metatarsal base, also known as Iselin's disease?

• A. Overuse injury osteochondrosis seen in adults
• B. Trauma leading to fracture
• C. Overuse injury osteochondrosis seen in growing children
• D. Infectious disease affecting the bones

Answer: (C)

Iselin's disease, characterized by apophysitis of the fifth metatarsal base, primarily affects growing children due to overuse injuries. The condition results from repetitive stress on the growth plate at the base of the fifth metatarsal, causing inflammation and pain. This overuse is more pronounced in active children who participate in running or jumping activities that put extra strain on their feet. In children, the bones and growth plates are still developing; thus, excessive biomechanical stress can lead to inflammation and irritation in the area where the tendons attach. As the child continues their activities without adequate rest, the condition can worsen. The awareness of this injury is particularly important in pediatric populations, as they are more susceptible to these types of conditions due to the differing mechanical properties of their bones compared to adults. Understanding this mechanism is essential for recognizing the signs of Iselin's disease early on and treating it effectively to prevent further complications.
