Overview
Hammer toes are usually not a serious condition, but can become painful as the bent joint rubs against the inside of the shoe, causing irritation, corns, or calluses on the top of the middle joint or the tip of the toe. A Hammer toes may also cause occasional shooting pains throughout the toes or elsewhere in the foot. A hammertoe has a kink or contracture in its second joint--called the proximal interphalangeal joint--that causes the toe to bend upward in the middle, giving it a hammer-like appearance. The raised part of the toe often rubs on shoes, leading to the formation of corns or calluses. Usually hammertoe affects the smaller toes, causing pain and interfering with the ability to walk normally.

Causes
Footwear is actually the leading cause of this type of toe deformity so much so that people sometimes require hammer toe surgery to undo some of the damage. The most common problem is wearing shoes that are too short, too narrow or too tight. These shoes constricts the feet and force the toes into a bend position. Women are more at risk especially due to high heels. Footwear isn?t the only problem, poor foot posture can lead to muscle and even bone imbalances. This asymmetry can cause excessive strain on the toes either by forcing the toe into unnatural positions. Arthritis can also play a factor in the development of hammer toe, especially if the toe joint is stiff and incapable of a full range of motion.

Symptoms
The most obvious symptoms of this injury will be the the middle toe joint is permanently bent at an angle. In the beginning movement may still be possible but as time passes and the injury worsens the toe will be locked in place and possible require hammer toe correction surgery to fix. Another key indicator of hammer toe is that a lump or corn will form on top of the toe. The toe joint will be painful and walking can cause severe discomfort. Occasionally a callus may form on the sole of the injured foot. If you see any of these symptoms together or have been enduring pain for some time, seeing a podiatrist should be your next step.

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
What will a doctor do? Treat any foot complaints such as corns, calluses by periodically reducing the lesion and applying appropriate pads and dressings. Recommend the silicone toe prop. If an infection is present, then anti-septic dressings, antibiotics and pads to redistribute pressure away from the lesion may be necessary. In the case of a mallet toe, trigger toe or claw toe. If a corn occurs at the end of the toe, a silicone or leather prop may be used to straighten the toe. In a hammertoe deformity, a silicone prop to redistribute pressure away from a corn may be necessary. The doctor may give footwear advice. In severe cases, corrective surgery may be necessary. The doctor may recommend orthosis to correct a mechanical complaint of the foot, such as 3/4 length silicone insoles.

Surgical Treatment
Curative treatment of hammertoes varies depending upon the severity of the deformity. When the hammertoe is flexible, a simple tendon release in the toe works well. The recovery is rapid often requiring nothing more that a single stitch and a Band-Aid. Of course if several toes are done at the same time, the recovery make take a bit longer.
