A Hammer toes is a toe that is bent because of a weakened muscle. The weakened muscle makes the tendons (tissues that connect muscles to bone) shorter, causing the toes to curl under the feet. Hammertoes can run in families. They can also be caused by shoes that are too short. Hammertoes can cause problems with walking and can lead to other foot problems, such as blisters, calluses, and sores. Splinting and corrective footwear can help in treating hammertoes. In severe cases, surgery to straighten the toe may be necessary.
Causes
Shoes that narrow toward the toe may make your forefoot look smaller. But they also push the smaller toes into a flexed (bent) position. The toes rub against the shoe, leading to the formation of corns and calluses, which further aggravate the condition. A higher heel forces the foot down and squishes the toes against the shoe, increasing the pressure and the bend in the toe. Eventually, the toe muscles become unable to straighten the toe, even when there is no confining shoe.

Symptoms
For some people, a hammer toe is nothing more than an unsightly deformity that detracts from the appearance of the foot. However, discomfort may develop if a corn or callus develops on the end or top of the toe. If pressure and friction continue on the end or top of the toe, a painful ulcer may develop. Discomfort or pain can lead to difficulty walking.
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
Hammer toes may be effectively corrected in different ways. Treatments can be non-invasive and involve physical therapy along with the advice that the person not wear any more shoes that restrict appropriate space for their toes. Appropriate shoes for people who want to avoid hammer toes, or for people who already have them, should be at least half an inch longer than the person's longest toe. High-heeled shoes are something to definitely avoid.
Surgical Treatment
Sometimes surgery can not be avoided. If needed, the surgery chosen is decided by whether we are dealing with a flexible or rigid hammer toe. If the surgery is on a flexible hammer toe, it is performed on soft tissue structures like the tendon and or capsule of the flexor hammer toe. Rigid hammer toes need bone surgeries into the joint of the toe to repair it. This bone surgery is called an arthroplasty.

Prevention
As long as hammertoe causes no pain or any change in your walking or running gait, it isn?t harmful and doesn't require treatment. The key to prevention is to wear shoes that fit you properly and provide plenty of room for your toes.
