Do you have a subungual exostosis? Say what? Yeah—sounds pretty bad, huh? A subungual exostosis is more commonly known as a bone spur under a toenail. 

Some reliable symptoms are pain or redness usually in the middle of the nail on the big toe, or a nail that is raised up in the middle.  Sometimes there are skin changes around the tip of the nail as well.  Recurring ingrown nails that remain painful are another sign.

They generally result from some form of trauma to the toe, forming a bony irregularity or prominence. We treat them with a simple outpatient procedure.

They sound painful and they are painful. The pain results from the pressure applied to the nail bed and plate. They can also cause destruction and disfigurement of the nail bed. Yup, they’re not pretty!

Other small tumors called osteochondromas and enchondromas can also form in the bone beneath the toenail, as well as in other bones in the body. Subungual exostosis should not be confused with these other small tumors.  Osteochondromas  are abnormal growths that form on the surface of a bone near the growth plate. An enchondroma is a type of benign bone tumor that originates from cartilage.

And that’s your science lesson for today! Any questions? 🙂
