Overview
Hammer toes are usually not a serious condition, but can become painful as the bent joint rubs against the inside of the shoe, causing irritation, corns, or calluses on the top of the middle joint or the tip of the toe. A Hammertoe may also cause occasional shooting pains throughout the toes or elsewhere in the foot. A hammertoe has a kink or contracture in its second joint--called the proximal interphalangeal joint--that causes the toe to bend upward in the middle, giving it a hammer-like appearance. The raised part of the toe often rubs on shoes, leading to the formation of corns or calluses. Usually hammertoe affects the smaller toes, causing pain and interfering with the ability to walk normally.

Causes
Most hammertoes are caused by wearing ill-fitting, tight or high-heeled shoes over a long period of time. Shoes that don?t fit well can crowd the toes, putting pressure on the middle toes and causing them to curl downward. Other causes include genes. Some people are born with hammertoe, bunions. These knobby bumps sometimes develop at the side of the big toe. This can make the big toe bend toward the other toes. The big toe can then overlap and crowd the smaller toes. Arthritis in a toe joint can lead to hammertoe.

Symptoms
Pain on the bottom of your foot, especially under the ball of your foot, is one of the most common symptoms associated with hammertoes. Other common signs and symptoms of hammertoes include pain at the top of your bent toe from footwear pressure. Corns on the top of your bent toe. Redness and swelling in your affected area. Decreased joint range of motion in your affected toe joints.

Diagnosis
A hammertoe is usually diagnosed with a physical inspection of your toe. Imaging tests, such as X-rays, may be ordered if you have had a bone, muscle, or ligament injury in your toe.

Non Surgical Treatment
Orthotics are shoe inserts that can help correct mechanical foot-motion problems to correct pressure on your toe or toes and reduce pain. Changing shoes. You should seek out shoes that conform to the shape of your feet as much as possible and provide plenty of room in the toe box, ensuring that your toes are not pinched or squeezed. You should make sure that, while standing, there is a half inch of space for your longest toe at the end of each shoe. Make sure the ball of your foot fits comfortably in the widest part of the shoe. Feet normally swell during the course of the day, so shop for shoes at the end of the day, when your feet are at their largest. Don't be vain about your shoe size, sizes vary by brand, so concentrate on making certain your shoes are comfortable. Remember that your two feet are very likely to be different sizes and fit your shoe size to the larger foot. Low-heel shoes. High heels shift all your body weight onto your toes, tremendously increasing the pressure on them and the joints associated with them. Instead, wear shoes with low (less than two inches) or flat heels that fit your foot comfortably.

Surgical Treatment
If conservative treatments fail and your symptoms persist, the doctor may recommend a surgical option to straighten the toe. The procedures used vary greatly, depending upon the reasons for the hammertoe. There are a number of different operations to correct hammertoes, the most common ones involve Soft tissue corrections such as tendon transfers, tendon lengthening, and joint capsule repairs. Digital arthroplasty involves removal of bone from the bent joint to allow the toe to straighten. The temporary use of pins or K-wires may be necessary to keep the toe straight during the healing period. Joint implants are sometimes used to allow for a better range of motion in the toe following surgery. Digital arthrodesis involves the removal of bone from the bent joint and fusing the toe in a straight position. If the corn is due to a bone spur, the most common procedure used is an exostectomy, in which surgically removing it or filing it down removes the bone spur. Because of the possible complications involved with any surgery, one should be sure to understand the risks that may be involved with surgery to correct hammertoes and remove bone spurs.

Prevention
To help prevent hammer toes from developing, wear shoes or boots that provide sufficient width in the toe box to ensure minimal compression. Use inserts that help the toes flatten out and spread and give sufficient support to the metatarsal arch in the forefoot. If hammer toes have already formed, padded socks help protect the tops and the tips of the hammer toes and may reduce pain from rubbing and chafing.
