Toe problems and toe deformities such as claw toe and Hammer toes happen when the tendons (guiders) that move the toes get too tight or out of balance. The affected toe can rub on other toes and on the inside of your shoe, causing pressure and pain. Inflammatory arthritis, (swelling, pain, stiffness in joints), which, such as rheumatoid arthritis can damage the toe joints and this may make them come out of position (dislocate).
Causes
The muscles of each toe work in pairs. When the toe muscles get out of balance, a hammer toe can form. Muscle imbalance puts a lot of pressure on the toe's tendons and joints. This pressure forces the toe into a hammerhead shape. How do the toe muscles get out of balance? There are three main reasons. Your genes, you may have inherited a tendency to develop hammer toes because your foot is slightly unstable - such as a flat foot. But high-arched feet can also get hammer toes. Arthritis. Injury to the toe: ill-fitting shoes are the main culprits of this cause. If shoes are too tight, too short, or too pointy, they push the toes out of balance. Pointy, high-heeled shoes put particularly severe pressure on the toes.

A hammertoe causes you discomfort when you walk. It can also cause you pain when trying to stretch or move the affected toe or those around it. Hammertoe symptoms may be mild or severe. Mild Symptoms, a toe that is bent downward, corns or calluses. Severe Symptoms, difficulty walking, the inability to flex your foot or wiggle your toes, claw-like toes. See your doctor or podiatrist right away if you develop any of these symptoms.
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
Conservative treatment is the first choice, often starting with a change of shoes to ones that have soft, larger toe spaces. Toe exercises may be prescribed to stretch and strengthen the toe muscles. Over-the-counter straps, cushions or non-medicated corn pads may be recommended to help relieve your symptoms.
Surgical Treatment
Hammer toe can be corrected by surgery if conservative measures fail. Usually, surgery is done on an outpatient basis with a local anesthetic. The actual procedure will depend on the type and extent of the deformity. After the surgery, there may be some stiffness, swelling and redness and the toe may be slightly longer or shorter than before. You will be able to walk, but should not plan any long hikes while the toe heals, and should keep your foot elevated as much as Hammer toe possible.
