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
While ill-fitting shoes may contribute to a hammertoe, shoes don't actually cause it, Hammertoes occur by the pull and stretch of the tendon. One tendon gets a more mechanical advantage over the other and allows the deformity to occur. Not surprisingly, wearing shoes that are too tight can make a hammertoe worse. If you're fond of narrow, pointy-toed shoes or high-heeled pumps, keep in mind you're squeezing those toes and tendons, which may aggravate hammertoes.

Symptoms
For some people, a hammer toe is nothing more than an unsightly deformity that detracts from the appearance of the foot. However, discomfort may develop if a corn or callus develops on the end or top of the toe. If pressure and friction continue on the end or top of the toe, a painful ulcer may develop. Discomfort or pain can lead to difficulty walking.

Diagnosis
Your healthcare provider will examine your foot, checking for redness, swelling, corns, and calluses. Your provider will also measure the flexibility of your toes and test how much feeling you have in your toes. You may have blood tests to check for arthritis, diabetes, and infection.

Non Surgical Treatment
If your hammertoe problem is diagnosed as flexible hammertoe, there are a number of nonsurgical treatments that may be able to straighten out your toe or toes and return them to their proper alignment. Padding and Taping. Your physician may pad the boney top-part of your hammertoe as a means of relieving pain, and may tape your toes as a way to change their position, correct the muscle imbalance and relieve the pressure that led to the hammertoe's development. Medication. Anti-inflammatory drugs such as aspirin and ibuprofen can help deal with inflammation, swelling and pain caused by your hammertoe. Cortisone injections may be prescribed for the same purpose. If your hammertoe is a consequence of arthritis, your physician may prescribe medications for that.

Surgical Treatment
A variety of anaesthetic techniques are possible. Be sure an discuss this with your surgeon during your pre-op assessment. The type of surgery performed will depend on the problem with your toes and may involve releasing or lengthening tendons, putting joints back into place, straightening a toe and changing the shape of a bone.Your surgeon may fix the toes in place with wires or tiny screws.

Prevention
As long as hammertoe causes no pain or any change in your walking or running gait, it isn?t harmful and doesn't require treatment. The key to prevention is to wear shoes that fit you properly and provide plenty of room for your toes.
