Overview
A Hammertoes or contracted toe is a deformity of the proximal interphalangeal joint of the second, third, or fourth toe causing it to be permanently bent, resembling a hammer. Mallet toe is a similar condition affecting the distal interphalangeal joint. Claw toe is another similar condition, with dorsiflexion of the proximal phalanx on the lesser metatarsophalangeal joint, combined with flexion of both the proximal and distal interphalangeal joints. Claw toe can affect the second, third, fourth, or fifth toes.

Causes
A common cause of hammertoe and mallet toe is wearing improper footwear - shoes that are too tight in the toe box, or high-heel shoes. Wearing shoes of either type can push your toes forward, crowding one or more of them into a space that's not large enough to allow your toes to lie flat. Hammertoe and mallet toe deformities can also be inherited and may occur despite wearing appropriate footwear. The result is a toe that bends upward in the middle and then curls down in a hammer-like or claw-like shape. Your shoes can rub against the raised portion of the toe or toes, causing painful corns or calluses. The bottom of the affected toe can press down, creating the mallet-like appearance of mallet toe. At first, a hammertoe or mallet toe may maintain its flexibility and lie flat when you're not wearing crowded footwear. But eventually, the tendons of the toe may contract and tighten, causing your toe to become permanently stiff.

Symptoms
Pain on the bottom of your foot, especially under the ball of your foot, is one of the most common symptoms associated with hammertoes. Other common signs and symptoms of hammertoes include pain at the top of your bent toe from footwear pressure. Corns on the top of your bent toe. Redness and swelling in your affected area. Decreased joint range of motion in your affected toe joints.

Diagnosis
Some questions your doctor may ask of you include, when did you first begin having foot problems? How much pain are your feet or toes causing you? Where is the pain located? What, if anything, seems to improve your symptoms? What, if anything, appears to worsen your symptoms? What kind of shoes do you normally wear? Your doctor can diagnose hammertoe or mallet toe by examining your foot. Your doctor may also order X-rays to further evaluate the bones and joints of your feet and toes.

Non Surgical Treatment
Hammertoes that are not painful (asymptomatic) and still flexible may not require treatment. In mild cases, open-toed, low-heeled, or wider shoes and foam or moleskin pads can provide symptomatic relief by reducing pressure. Taping (strapping) the affected toe can help to reduce deformity and pain. Physical therapy to instruct patients in exercises that passively stretch tight structures and strengthen weak foot intrinsic muscles is also helpful with mild cases. Periodic trimming (debridement) of corns (clavi, helomata) by a podiatrist can provide temporary relief. Corticosteroid injections are often very effective in reducing pain.

Surgical Treatment
Surgery to correct for a hammertoe may be performed as a day procedure. There are several different types of procedures that can be used depending on the foot structure and if the deformity is flexible or rigid.

Prevention
These tips may help you buy the right shoes. Buy shoes at the end of the day. Your feet are smaller in the morning and swell throughout the day. Don't assume your shoe size hasn't changed. As you age, your shoe size may change, especially the width. Measure both feet and buy for the larger foot. Ask for just the right fit. A shoe repair store can stretch shoes in tight spots.
