Information for Patients


Toe Injuries and Disorders

Fourteen of the 26 bones in your feet are in your toes. The toes, particularly your big toe, help you move and keep your balance. Playing sports, running, stubbing your toe, and dropping something on your foot can damage your toes. Wearing shoes that are too loose or too tight can also cause toe problems. Certain diseases, such as severe arthritis, can cause toe problems and pain. Gout often causes pain in the big toe.

Common toe problems include

  • Corns and bunions
  • Ingrown toenails
  • Sprains and dislocations
  • Fractures

Treatments for toe injuries and disorders vary. They might include shoe inserts or special shoes, padding, taping, medicines, rest, and in severe cases, surgery.
