Recently I had a patient come to the office and we were discussing this problem of apophysitis. This is a painful growth plate that is seen in growing children. The most common one is in the back of the heel called Sever’s Disease (Calcaneal Apophysitis). Treatment for this condition with with pediatric Ibuprofen, icing, stretching (of the muscles or tendons pulling on the growth plate area) and physical therapy.
At times treatment can include a walking boot or even casting. Ultimately, we just want to reduce the pull on the growth plate until the patient finished growing in that area.
On the 5th metatarsal this is called Iselin’s Disease. You can see two photos from radiopaedia.org that shows this condition. (http://radiopaedia.org)
As you can see the area on the little toe side of the foot at the base there is a little piece of bone where the peroneous brevis attaches. The goal of treatment is to reduce pain.
If you would like to learn more about this condition here is a helpful article you can download and read (it is quite technical but has some good pictures). If I can help you understand more about it please ask me a question below.
To your health,
Dr. Donald Pelto
