hammertoe is foot deformity that typically affects second, third or fourth toes. The condition is called hammertoe because of the unnatural position your toes form. Hammertoe causes your toe to bend upward at the middle joint in a way that looks similar to a hammer. While it may not be painful at first, this condition usually worsens with time and it becomes difficult to extend your toes. Sometimes, calluses or corns form in association with hammertoe.
Causes
Hammertoe has three main culprits: tight shoes, trauma, and nerve injuries or disorders. When toes are crowded in shoes that are too tight and narrow, they are unable to rest flat, and this curled toe position may become permanent even when you aren't wearing shoes due to the tendons of the toe permanently tightening. When the tendons are held in one position for too long, the muscles tighten and eventually become unable to stretch back out. A similar situation may result when tendons are injured due to trauma, such as a stubbed, jammed, or broken toe.

The most obvious symptom of hammer, claw or mallet toe is the abnormal toe position. This is usually combined with pain: the abnormal foot position leads to excessive friction on the toe as it rubs against any footwear which can be extremely painful. Corns & Calluses: repeated friction can result in the formation of a foot corn or callus on top of the toes. Stiffness, the joints become increasingly stiff. In the early stages, the toes can usually be straightened out passively using your hands, but if Hammer toes allowed to progress, the stiffness may be permanent.
Diagnosis
Your doctor is very likely to be able to diagnose your hammertoe simply by examining your foot. Even before that, he or she will probably ask about your family and personal medical history and evaluate your gait as you walk and the types of shoes you wear. You'll be asked about your symptoms, when they started and when they occur. You may also be asked to flex your toe so that your doctor can get an idea of your range of motion. He or she may order x-rays in order to better define your deformity.
Non Surgical Treatment
Treating hammertoe involves straightening the toe, making tendons in the toes flexible again, and preventing the problem from returning. Some simple treatments include splinting the toe to keep it straight and to stretch the tendons of the foot. Using over-the-counter pads, cushions or straps to decrease discomfort Exercising the toes to relax the foot tendons (a session with a physical therapist may help you get started with foot exercises) Wearing shoes that fit properly and allow toes plenty of room to stretch out.
Surgical Treatment
In advanced cases in which the toe has become stiff and permanently bent, the toe can be straightened with surgery. One type of surgery involves removing a small section of the toe bone to allow the toe to lie flat. Surgery for hammertoe usually is classified as a cosmetic procedure. Cosmetic foot surgeries sometimes cause complications such as pain or numbness, so it?s better to treat the problem with a shoe that fits properly.
