If the joint on one of your toes - usually the toe next to the big toe or the smallest toe - points upward rather than lying flat, you might have a hammertoe. The condition is actually a deformity that happens when one of the toe muscles becomes weak and puts pressure on the toe's tendons and joints. This pressure forces the toe to become misshapen and stick up at the joint. Also, there's frequently a corn or callus on top of the deformed toe. This outgrowth can cause pain when it rubs against the shoe.
"The term, hammertoe, is commonly used as a general classification for any condition where the toe muscle weakens, causing digital contracture, and resulting in deformity," explains our very own Dr. Juliette Perez, DPM. But she adds that a digital contracture like this can actually be a hammertoe, claw toe or mallet toe, depending on which joints in the toe are contracted.
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) 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.
Diagnosis - 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. 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.
