Hammertoe is a deformity of the second, third, or fourth toes. In this condition, the toe is bent at the middle joint, causing it to resemble a hammer. Left untreated, hammertoes can become inflexible and require surgery. People with hammertoe may have corns or calluses on the top of the middle joint of the toe or on the tip of the toe. They may also feel pain in their toes or feet and have difficulty finding comfortable shoes.
It can happen to any toe. Women are more likely to get pain associated with hammertoes than men because of shoe gear.
Hammertoes can be a serious problem in people with diabetes or poor circulation. People with these conditions should see a doctor at the first sign of foot trouble.
There are two types of hammertoes:
Flexible hammertoes. If the toe still can be moved at the joint, it's a flexible hammertoe. That's good, because this is an earlier, milder form of the problem. There may be several treatment options.
Rigid hammertoes. If the tendons in the toe become rigid, they press the joint out of alignment. At this stage, the toe can't be moved. It usually means that surgery is needed.
