What is Hammertoe?
A hammer toe is a deformity of the second, third or fourth toes. In this condition, the toe is bent at the middle joint, so that it resembles a hammer. Initially, hammer toes are flexible and can be corrected with simple measures but, if left untreated, they can become fixed and require surgery.
People with hammer toe may have corns or calluses on the top of the middle joint of the toe or on the tip of the toe. They may also feel pain in their toes or feet and have difficulty finding comfortable shoes.
What Causes Hammertoe?
Hammer toe results from shoes that don’t fit properly or a muscle imbalance, usually in combination with one or more other factors. Muscles work in pairs to straighten and bend the toes. If the toe is bent and held in one position long enough, the muscles tighten and cannot stretch out.
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.
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 upon their location.
- Inflammation, redness, or a burning sensation
- Contracture of the toe
- In more severe cases of hammertoe, open sores may form.
How are Hammertoes Diagnosed?
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.
There is a variety of treatment options for hammertoe. The treatment your foot and ankle surgeon selects will depend upon the severity of your hammertoe and other factors.
A number of non-surgical measures can be undertaken:
- Padding corns and calluses. Your foot and ankle surgeon can provide or prescribe pads designed to shield corns from irritation. If you want to try over-the-counter pads, avoid the medicated types. Medicated pads are generally not recommended because they may contain a small amount of acid that can be harmful. Consult your surgeon about this option.
- Changes in shoewear. Avoid shoes with pointed toes, shoes that are too short, or shoes with high heels – conditions that can force your toe against the front of the shoe. Instead, choose comfortable shoes with a deep, roomy toe box and heels no higher than two inches.
- Orthotic devices. A custom orthotic device placed in your shoe may help control the muscle/tendon imbalance.
- Injection therapy. Corticosteroid injections are sometimes used to ease pain and inflammation caused by hammertoe.
- Medications. Oral nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be recommended to reduce pain and inflammation.
- Splinting/strapping. Splints or small straps may be applied by the surgeon to realign the bent toe.
When is Surgery Needed?
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.
