A hammer toe bends down toward the floor at the middle toe joint. This causes the middle toe joint to rise up. It usually affects the second toe. Hammer toes often occur with bunions.
What causes hammer toe?
Tight shoes are the most common cause. Wearing tight shoes can cause the toe muscles to get out of balance. If a shoe forces a toe to stay in a bent position for too long, the muscles tighten and the tendons shorten, or contract. This makes it harder to straighten the toe. Over time, the toe muscles can't straighten the toe, even when you aren't wearing shoes.
It can take years for a hammer toe to form. Women are affected more often than men because they are more likely to wear shoes with narrow toes or high heels.
Less often, these toe problems are linked with other conditions, such as diabetes, rheumatoid arthritis, stroke, or an injury to the foot or ankle.
What are the symptoms?
Your toe may be painful and it might be difficult to find shoes that fit or are comfortable to wear. The toe may rub against your footwear and cause calluses or corns. In more severe cases, these toe problems may affect your balance and make it hard to walk.
How is it diagnosed?
Your doctor will ask questions about your symptoms and past health and do a physical exam. Your doctor will want to know:
- When the problem began, what activities or shoes make them worse, and if other parts of the foot are painful.
- What kind of shoes you wear and how much time you spend standing or walking every day.
- Any previous foot problems you have had.
- Any medical conditions you have that could be related, such as arthritis, diabetes, or poor blood flow (circulation).
During the physical exam, your doctor will look at your foot to see if the toe joint is fixed or flexible. A joint that has some movement can sometimes be straightened without surgery. A fixed joint often requires surgery. You may need surgery if other treatments don't control your pain, if your toe limits activity, or if you can't move the toe joint (fixed toe problem). In general, surgery is used only for severe toe problems.
