Overview
Hammer Toe is often a harmless and painless condition. Although the toe may be curled permanently, hammertoe should not cause any long-term problems other than a more difficult time finding shoes that fit. If hammertoe is treated and preventive measures are followed, the condition should not return. Wearing tight or constricting shoes can cause hammertoe to return.

Causes
The APMA says that hammertoe can result from a muscle imbalance in the foot that puts undue pressure on the joints, ultimately causing deformity. Inherited factors can contribute to the likelihood of developing hammertoe. Arthritis, stroke or nerve damage from diabetes or toe injuries such as jamming or breaking a toe can affect muscle balance in the foot, leading to hammertoe. The Mayo Clinic says that wearing improper shoes often causes hammertoe. Shoes that squeeze the toes, such as those with a tight toe box or with heels higher than two inches, can put too much pressure on the toe joints.

Symptoms
If the toes remain in the hammertoe position for long periods, the tendons on the top of the foot will tighten over time because they are not stretched to their full length. Eventually, the tendons shorten enough that the toe stays bent, even when shoes are not being worn. The symptoms of hammertoe include a curling toe, pain or discomfort in the toes and ball of the foot or the front of the leg, especially when toes are stretched downward, thickening of the skin above or below the affected toe with the formation of corns or calluses, difficulty finding shoes that fit well. In its early stages, hammertoe is not obvious. Frequently, hammertoe does not cause any symptoms except for the claw-like toe shape.

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
Symptomatic treatment of hammertoes consists of such things as open toed shoes or hammertoe pads. There are over the counter corn removers for temporally reducing the painful callous often seen with the hammertoe. These medications must be used with caution. They are a mild acid that burns the callous off. These medications should never be used for corns or callouses between the toes. Persons with diabetes or bad circulation should never use these products.

Surgical Treatment
If these non-invasive treatments don?t work, or if the joint is rigid, a doctor?s only recourse may be to perform surgery. During the surgery, the doctor makes an incision and cuts the tendon to release it or moves the tendon away from or around the joint. Sometimes part of the joint needs to be removed or the joint needs to be fused. Each surgery is different in terms of what is needed to treat the hammertoe. Normally after any foot surgery, patients use a surgical shoe for four to six weeks, but often the recovery from hammertoe surgery is more rapid than that. An unfortunate reality is that hammertoe can actually return even after surgery if a patient continues to make choices that will aggravate the situation. Though doctors usually explain pretty clearly what needs to be done to avoid this.
