OverviewA Hammer toes is a contracture of the toes as a result of a muscle imbalance between the tendons on the top and the tendons on the bottom of the toe. They can be flexible or rigid in nature. When they are rigid, it is not possible to straighten the toe out by manipulating it. Frequently, they develop corns on the top of the toe as a result of rubbing on the shoe. They may also cause a bothersome callous on the ball of the foot. This occurs as a result of the toe pressing downward on the bone behind the toe. This area then becomes prominent and the pressure of the bone against the ground causes a callous to form.
Causes
Hammer toe is commonly caused by wearing shoes that are too narrow, tight or short on a regular basis. By doing so, your toe joints are forced into odd position. Over time, the tendons and muscles in your toe become shorter and cause it to bend. You can suffer a hammer toe if you have diabetes and the disease is worsening. If this occurs, you should contact your doctor right away. Arthritis can also cause hammer toes. Because your toe muscles get out of balance when you suffer from this joint disorder, tendons and joints of your toes are going to experience a lot of pressure.
Symptoms
Well-developed hammertoes are distinctive due to the abnormal bent shape of the toe. However, there are many other common symptoms. Some symptoms may be present before the toe becomes overly bent or fixed in the contracted position. Often, before the toe becomes permanently contracted, there will be pain or irritation over the top of the toe, particularly over the joint. The symptoms are pronounced while wearing shoes due to the top of the toe rubbing against the upper portion of the shoe. Often, there is a significant amount of friction between the toe and the shoe or between the toe and the toes on either side of it. The corns may be soft or hard, depending on their location and age. The affected toe may also appear red with irritated skin. In more severe cases, blisters or open sores may form. Those with diabetes should take extra care if they develop any of these symptoms, as they could lead to further complications.
Diagnosis
The exam may reveal a toe in which the near bone of the toe (proximal phalanx) is angled upward and the middle bone of the toe points in the opposite direction (plantar flexed). Toes may appear crooked or rotated. The involved joint may be painful when moved, or stiff. There may be areas of thickened skin (corns or calluses) on top of or between the toes, a callus may also be observed at the tip of the affected toe beneath the toenail. An attempt to passively correct the deformity will help elucidate the best treatment option as the examiner determines whether the toe is still flexible or not. It is advisable to assess palpable pulses, since their presence is associated with a good prognosis for healing after surgery. X-rays will demonstrate the contractures of the involved joints, as well as possible arthritic changes and bone enlargements (exostoses, spurs). X-rays of the involved foot are usually performed in a weight-bearing position.
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
Surgery to correct for a hammertoe may be performed as an outpatient procedure at a hospital, surgery center, or in the office of your podiatrist. There are multiple procedures that can be used depending on your individual foot structure and whether the deformity is flexible or rigid. There may be a surgical cut in the bone to get rid of an exostosis, or a joint may be completely removed to allow the toe to lay straight.
