OverviewA Hammer Toe 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 usually affects the second toe. However, it may also affect the other toes. The toe moves into a claw-like position. The most common cause of hammer toe is wearing short, narrow shoes that are too tight. The toe is forced into a bent position. Muscles and tendons in the toe tighten and become shorter. Hammer toe is more likely to occur in women who wear shoes that do not fit well or have high heels and children who keep wearing shoes they have outgrown. The condition may be present at birth (congenital) or develop over time. In rare cases, all of the toes are affected. This may be caused by a problem with the nerves or spinal cord.
Symptoms
A soft corn, or heloma molle, may exist in the web space between toes. This is more commonly caused by an exostosis, which is basically an extra growth of bone possibly due to your foot structure. As this outgrowth of excessive bone rubs against other toes, there is friction between the toes and a corn forms for your protection.
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
Prescription strength medicines to decrease pain and inflammation. Physical Therapy. To strengthen poorly functioning muscles and stretch tight muscles that may be exacerbating the toes. Special ultrasound techniques may reduce inflammation. Custom Foot Orthotics. An orthotic with an exact mold of your foot to better align and support the foot to ease current discomfort and prevent future progression. Toe Splints or Pads. Specific pads may prevent pressure and physical irritation in shoes. Toe splints and toe spacers physically realign the toes and can lessen pain and halt or stall hammer toe progression. Cortisone injections are strong anti-inflammatory agents to decrease pain, and swelling directly at the toe region. Injections only treat the symptoms, and in some cases used in caution (and sparingly) they can weaken supporting ligaments of the toe(s).
Surgical Treatment
Hammertoe surgery is performed when conservative measures have been exhausted and pain or deformity still persists. The surgery is performed on an outpatient basis. It typically required about one hour of time. An incision is placed over the inter-phalangeal joint. Once the bone is exposed, the end portion of the bone is removed. Your surgeon may then use pins or other fixation devices to assist in straightening the toe. These devices may be removed at a later date if necessary. Recovery for hammertoe surgery is approximately 10 to 14 days. You are able to walk immediately following the surgery in a surgical shoe. Swelling may be present but is managed as needed. Physical therapy is used to help reduce swelling in the toe or toes after surgery. Most of these toe surgeries can be performed in the office or the outpatient surgery under local anesthesia.
Prevention
Some different things you can do to help prevent hammer toes from forming and progressing do exist. You can wear supportive shoes to help prevent deformities. Hammer toes are often times related to poor foot mechanics, particularly foot flattening. You can wear custom orthotics prescribed by a podiatrist; orthotics might prevent or slow the progression of hammer toes. You can also avoid shoes with narrow or pointed toe boxes that can compress your toes.
