Hammertoe is a contracture (bending) deformity of one or both joints of the second, third, fourth, or fifth (little) toes. This abnormal bending can put pressure on the toe when wearing shoes, causing problems to develop.
Hammertoes usually start out as mild deformities and get progressively worse over time. In the earlier stages, hammertoes are flexible and the symptoms can often be managed with noninvasive measures. But if left untreated, hammertoes can become more rigid and will not respond to nonsurgical treatment.
Because of the progressive nature of hammertoes, they should receive early attention. Hammertoes never get better without some kind of intervention.
Causes
The most common cause of hammertoe is a muscle/tendon imbalance. This imbalance, which leads to a bending of the toe, results from mechanical (structural) or neurological changes in the foot that occur over time in some people.
Hammertoes may be aggravated by shoes that don’t fit properly. A hammertoe may result if a toe is too long and is forced into a cramped position when a tight shoe is worn. Occasionally, hammertoe is the result of an earlier trauma to the toe. In some people, hammertoes are inherited.
Symptoms
Common symptoms of hammertoes include:
- Pain or irritation of the affected toe when wearing shoes.
- Corns and calluses (a buildup of skin) on the toe, between two toes or on the ball of the foot. Corns are caused by constant friction against the shoe. They may be soft or hard, depending on their location.
- Inflammation, redness or a burning sensation
- Contracture of the toe
- In more severe cases of hammertoe, open sores may form.
Hammertoes are progressive—they don’t go away by themselves and usually they will get worse over time. However, not all cases are alike—some hammertoes progress more rapidly than others. Once your foot and ankle surgeon has evaluated your hammertoes, a treatment plan can be developed that is suited to your needs. In some cases, usually when the hammertoe has become more rigid and painful, or when an open sore has developed, surgery is needed.
Often, patients with hammertoe have bunions or other foot deformities corrected at the same time. In selecting the procedure or combination of procedures for your particular case, the foot and ankle surgeon will take into consideration the extent of your deformity, the number of toes involved, your age, your activity level, and other factors. The length of the recovery period will vary, depending on the procedure or procedures performed.
