An overgrowth of bone under the toenail can press up into the tissue underneath the growth plate, deforming the nail above. This condition is painful, especially when you’re wearing shoes. Many people also find that weight-bearing is difficult.

Treatment: Subungual Exostosis.
The bone spur can be smoothed down with a tiny rasp. The rasp (which resembles a dental burr) is inserted through a small incision in the toe. This procedure is often performed along with partial or total matricectomy.

Follow-up Care:
Your incision is bandaged, and you can bear weight immediately. Often, you can wear your own shoes after surgery.
