Overview
Hammer toes are classified based on the mobility of the toe joints. There are two types. Flexible and rigid. In a flexible Hammer toes, the joint has the ability to move. This type of hammer toe can be straightened manually. A rigid hammer toe does not have that same ability to move. Movement is very limited and can be extremely painful. This sometimes causes foot movement to become restricted leading to extra stress at the ball-of-the-foot, and possibly causing pain and the development of corns and calluses.
Causes
The APMA says that hammertoe can result from a muscle imbalance in the foot that puts undue pressure on the joints, ultimately causing deformity. Inherited factors can contribute to the likelihood of developing hammertoe. Arthritis, stroke or nerve damage from diabetes or toe injuries such as jamming or breaking a toe can affect muscle balance in the foot, leading to hammertoe. The Mayo Clinic says that wearing improper shoes often causes hammertoe. Shoes that squeeze the toes, such as those with a tight toe box or with heels higher than two inches, can put too much pressure on the toe joints.
Symptoms
The most obvious sign of hammertoes are bent toes, other symptoms may include pain and stiffness during movement of the toe. Painful corns on the tops of the toe or toes from rubbing against the top of the shoe's toe box. Painful calluses on the bottoms of the toe or toes. Pain on the bottom of the ball of the foot. Redness and swelling at the joints.
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 hammertoe corns and calluses. You should not try to remove them at home.
Surgical Treatment
In more advanced cases of hammer toe, or when the accompanying pain cannot be relieved by conservative treatment, surgery may be required. Different types of surgical procedures are performed to correct hammer toe, depending on the location and extent of the problem. Surgical treatment is generally effective for both flexible and fixed (rigid) forms of hammer toe. Recurrence following surgery may develop in persons with flexible hammer toe, particularly if they resume wearing poorly-fitted shoes after the deformity is corrected.
