Bunions

Definition

A bunion forms when your big toe points toward the second toe. This causes a bump to appear on the inside edge of your toe.

Causes

Bunions are more common in women than men. The problem can run in families. People born with abnormal bones in their feet are more likely to form a bunion.

Wearing narrow-toed, high-heeled shoes may lead to the development of a bunion.

The condition may become painful as the bump gets worse. Extra bone and a fluid-filled sac grow at the base of the big toe.

Symptoms

Symptoms may include:

You may have problems finding shoes that fit or that do not cause pain.

Exams and Tests

A health care provider can very often diagnose a bunion by looking at it. A foot x-ray can show an abnormal angle between the big toe and the foot. In some cases, arthritis may also be seen.

Treatment

When a bunion first begins to develop, take good care of your feet.

If the bunion gets worse and more painful, surgery may help. The surgery bunionectomy realigns the toe and removes the bony bump. There are more than 100 different surgeries to treat this condition.

Outlook (Prognosis)

You can keep a bunion from worsening by taking care of it. Try to wear different shoes when it first starts to develop.

Teenagers may have more trouble treating a bunion than adults. This may be the result of an underlying bone problem.

Surgery reduces the pain in many, but not all people with bunions. After surgery, you may not be able to wear tight or fashionable shoes.
