Overview
Hammer toes is most common in women, and a big part of this is poor shoe choices, which are a big factor in the development of many foot problems. Tight toe boxes and high heels are the biggest culprits. Genetics certainly plays a role in some cases of hammertoes, as does trauma, infection, arthritis, and certain neurological and muscle disorders. Most cases of contracted toes are associated with various biomechanical abnormalities in how a patient walks. This causes the muscles and tendons to be used excessively or improperly, which deforms the toes over time.

Causes
Hammertoe commonly develops because of structural changes that take place over time in the muscles and tendons that bend the toes. People with certain medical conditions, such as diabetes, are at risk for developing hammertoe. It can be an inherited condition for some people. Other causes include trauma and wearing shoes that are too tight, narrow, or have high heels. The toe next to the big toe (second toe) is most frequently affected by hammertoe.

Symptoms
Patients with hammer toe(s) may develop pain on the top of the toe(s), tip of the toe, and/or on the ball of the foot. Excessive pressure from shoes may result in the formation of a hardened portion of skin (corn or callus) on the knuckle and/or ball of the foot. Some people may not recognize that they have a hammer toe, rather they identity the excess skin build-up of a corn.The toe(s) may become irritated, red, warm, and/or swollen. The pain may be dull and mild or severe and sharp. Pain is often made worse by shoes, especially shoes that crowd the toes. While some hammer toes may result in significant pain, others may not be painful at all. Painful toes can prevent you from wearing stylish shoes.

Diagnosis
Most health care professionals can diagnose hammertoe simply by examining your toes and feet. X-rays of the feet are not needed to diagnose hammertoe, but they may be useful to look for signs of some types of arthritis (such as rheumatoid arthritis) or other disorders that can cause hammertoe. If the deformed toe is very painful, your doctor may recommend that you have a fluid sample withdrawn from the joint with a needle so the fluid can be checked for signs of infection or gout (arthritis from crystal deposits).

Non Surgical Treatment
Hammer toes usually get progressively worse over time, especially if you avoid seeking care. Not all cases are the same, so it is important to get your podiatrist or foot surgeon to evaluate your condition so that you can get the treatment you need as soon as possible. Your treatment options will vary depending on the severity of your hammer toe. You may not require surgery to treat your hammer toe. Your doctor may suggest one of these less invasive measures. Instead of wearing shoes that are too high or too short, wear comfortable shoes that have plenty of room and are flat or low-heeled. Your doctor can prescribe pads that will prevent your corns or calluses from getting irritated. Avoid over-the-counter medicated pads, as they contain acid that can worsen your condition. An orthotic device can be customized to fit your shoe and foot. It can help control your tendon and muscle imbalance, which in turn may ease your pain. NSAIDS (nonsteroidal anti-inflammatory drugs) such as ibuprofen can reduce inflammation. By relieving swelling in your toe joint, you can alleviate your pain. Splints or small straps can be placed on your toe by a foot surgeon to realign your bent toe. Applying ice packs wrapped in cloth on your hammer toe can reduce inflammation and swelling. Gently massaging your toes can assist in alleviating your pain caused by hammer toes. Try exercises that stretch your feet as these can help restore your muscle balance. A simple exercise that can help is to pick up a cloth or small object from the floor by curling your toes. This action will help your feet and toes by stretching them.

Surgical Treatment
Joint resection procedures involves removing part of one of the two small joints of the toe directly underneath where the digit is crooked. The purpose is to make room for the toe to be re-positioned flat or straight. Because hammer toes become rigid or fixed with time, removing the joint becomes the only option when the knuckle is stiff. Its important to understand that this procedure does not involve the joint of the ball of the foot, rather the a small joint of the toe. Medical terminology for this procedure is called a proximal interphalangeal joint arthroplasty or a distal interphalangeal joint arthroplasty, with the latter involving the joint closer to the tip of the toe.

Prevention
Some different things you can do to help prevent hammer toes from forming and progressing do exist. You can wear supportive shoes to help prevent deformities. Hammer toes are often times related to poor foot mechanics, particularly foot flattening. You can wear custom orthotics prescribed by a podiatrist; orthotics might prevent or slow the progression of hammer toes. You can also avoid shoes with narrow or pointed toe boxes that can compress your toes.
