Category: Hammer Toe


The term, Hammer toe, is commonly used as a general classification for any condition where the toe muscle weakens, causing digital contracture, and resulting in deformity, a digital contracture like this can actually be a hammertoe, claw toe or mallet toe, depending on which joints in the toe are contracted. Clawtoes are bent at the middle and end joints, while hammertoes are bent at the middle joint only. When it?s mallet toe, the joint at the end of the toe buckles. The skin near the toenail tip develops a painful corn that can eventually result in an ulcer. Doctors further categorize all forms of hammertoe based on whether the affected toe is flexible, semi-rigid or rigid. The more rigid the toe, the more pain it will cause.


Shoes that narrow toward the toe may make your forefoot look smaller. But they also push the smaller toes into a flexed (bent) position. The toes rub against the shoe, leading to the formation of corns and calluses, which further aggravate the condition. A higher heel forces the foot down and squishes the toes against the shoe, increasing the pressure and the bend in the toe. Eventually, the toe muscles become unable to straighten the toe, even when there is no confining shoe.

Hammer ToeSymptoms

The symptoms of a hammer toe are usually first noticed when a corn develops on the top of the toe and becomes painful, usually when wearing tight shoes. There may be a bursa under the corn or instead of a corn, depending on the pressure. Most of the symptoms are due to pressure from footwear on the toe. There may be a callus under the metatarsal head at the base of the toe. Initially a hammer toe is usually flexible, but when longstanding it becomes more rigid.


Your doctor is very likely to be able to diagnose your hammertoe simply by examining your foot. Even before that, he or she will probably ask about your family and personal medical history and evaluate your gait as you walk and the types of shoes you wear. You’ll be asked about your symptoms, when they started and when they occur. You may also be asked to flex your toe so that your doctor can get an idea of your range of motion. He or she may order x-rays in order to better define your deformity.

Non Surgical Treatment

There are many non-surgical treatments to help relieve symptoms of hammertoe. The first step for many people is wearing the right size and type of shoe. Low-heeled shoes with a boxy or roomy toe area are helpful. Cushioned insoles, customized orthopedic inserts, and pads can provided relief as well. Splints or straps may be used to help correct toe position. Your doctor may show you toe stretches and exercises to perform. Your doctor can safely remove corns and calluses. You should not try to remove them at home.

Surgical Treatment

Several surgical procedures are available to the podiatric physician. For less severe deformities, the surgery will remove the bony prominence and restore normal alignment of the toe joint, thus relieving pain. Severe hammertoes, which are not fully reducible, may require more complex surgical procedures. Recuperation takes time, and some swelling and discomfort are common for several weeks following surgery. Any hammertoes pain, however, is easily managed with medications prescribed by your podiatric physician.
