OverviewHammertoe 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.
Causes
The constant pressure a woman's foot receives in high-heeled shoes due to the force of gravity causes their feet to naturally slide down and press on the lowest point of the shoe so they are not able to receive enough space and stretch out. The result is an eventual distortion of the woman's toes. The deformity comes as a result of the shortening of muscles inside the toes because the toes become used to being in a bent position, prompting the muscles to fail to extend any further and become tightened and curbed. At first, toes may still be stretched out if poor footwear is not being worn, yet if the habit is persistent...the person's toes will eventually become used to the position they are constantly in and muscle fibers inside them will harden and refuse to stretch.
Symptoms
People with a hammer toe will often find that a corn or callus will develop on the top of the toe, where it rubs against the top of the footwear. This can be painful when pressure is applied or when anything rubs on it. The affected joint may also be painful and appear swollen.
Diagnosis
First push up on the bottom of the metatarsal head associated with the affected toe and see if the toe straightens out. If it does, then an orthotic could correct the problem, usually with a metatarsal pad. If the toe does not straighten out when the metatarsal head is pushed up, then that indicates that contracture in the capsule and ligaments (capsule contracts because the joint was in the wrong position for too long) of the MTP joint has set in and surgery is required. Orthotics are generally required post-surgically.
Non Surgical Treatment
Symptoms of hammer toe might be helped through corn pads or cushions to alleviate them. If the person's hammer toes were caused by an underlying disease, the person should ask for their doctor's advice prior to performing any exercises without consent. It is also important for a person with hammer toes to remember that they must not attempt to treat or remove corns by themselves. If open cuts result from attempts to remove them, an infection becomes a very real possibility. People who experience diabetes or conditions that lead to poor circulation in their feet need to be especially careful.
Surgical Treatment
For severe hammer toe, you will need an operation to straighten the joint. The surgery often involves cutting or moving tendons and ligaments. Sometimes the bones on each side of the joint need to be connected (fused) together. Most of the time, you will go home on the same day as the surgery. The toe may still be stiff afterward, and it may be shorter. If the condition is treated early, you can often avoid surgery. Treatment will reduce pain and walking difficulty.
Prevention
There should be at least one-half inch between the tip of your longest toe and the front of the shoe. Never buy shoes that feel tight and expect them to stretch with wearing. If you have prominent areas on your feet such as hammertoes and bunions, avoid shoes with a lot of stitching or multiple pieces of fabric, as these stitched areas tend not to stretch to accommodate various toe deformities.
