Hammer toe is caused when the middle joint (PIP) bends down towards the floor (flexion). To compensate, the joints above and below (MTP, DIP) bend up (hyperextend). The result is that the middle part of the toe lifts up. Hammertoe is the most common deformity of the lesser toes (i.e. not the big toe). It tends to only affect one toe, most commonly the second.
While there are a number of causes, there aren't many specific risk factors for hammertoes, women tend to get these problems more than men, but they occur without rhyme or reason. Diabetics, however, are more likely to get a hammertoe if they have underlying nerve damage in the toes and feet.
Signs and symptoms of hammertoe and mallet toe may include a hammer-like or claw-like appearance of a toe. In mallet toe, a deformity at the end of the toe, giving the toe a mallet-like appearance. Pain and difficulty moving the toe. Corns and calluses resulting from the toe rubbing against the inside of your footwear. Both hammertoe and mallet toe can cause pain with walking and other foot movements.
Although hammertoes are readily apparent, to arrive at a diagnosis the foot and ankle surgeon will obtain a thorough history of your symptoms and examine your foot. During the physical examination, the doctor may attempt to reproduce your symptoms by manipulating your foot and will study the contractures of the toes. In addition, the foot and ankle surgeon may take x-rays to determine the degree of the deformities and assess any changes that may have occurred.
Non Surgical Treatment
Conservative treatment starts with new shoes that have soft, roomy toe boxes. Shoes should be one-half inch longer than your longest toe. For many people, the second toe is longer than the big toe.) Avoid wearing tight, narrow, high-heeled shoes. You may also be able to find hammertoe a shoe with a deep toe box that accommodates the hammer toe. Or, a shoe repair shop may be able to stretch the toe box so that it bulges out around the toe. Sandals may help, as long as they do not pinch or rub other areas of the foot.
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.
