This is a picture of a patient that previously had the whole nail removed permanently using a procedure called a matrixectomy. That’s where you kill the root of the nail. As you can see, there’s a little piece of nail that comes back. This is called a nail spicule. This happens because when you put the medication in the base of the nail, it’s kind of inexact because you just rub it around both edges and along the base of the nail, and hopefully it doesn’t come back. Occasionally there is a little spicule that can grow back and you can either trim this down on your own or if needed, you can retreat this so it doesn’t come back again.  There is always a risk of having it come back, but usually the second or third time is a charm.
