Hammertoes result from an abnormal imbalance of the muscles of the toes. The toes become bent at the small joints of the lesser toes. Hammertoes worsen over time and can result in painful calluses. Certain risk factors such as diabetes and arthritic diseases can make you more prone to developing foot deformities. Heredity may also play a role. Hammertoes can be surgically corrected. Your physician can provide a surgical consultation for you.
