Overview
A Hammer Toe occurs when the joint of the toes curl down. The reason they curl abnormally is due to a muscle imbalance which results in the tendons becoming unnaturally tight. They are due to Heredity, improper shoes, and Arthritis. There are two types of hammer toes, flexible or rigid. These classification are based on the mobility of the toe joints. A flexible hammer toe is one with a flexible toe joint that allows it to be straightend with your finger. In time a flexible joint may turn into a rigid hammer toe. Normally flexible hammer toes are much less painful than rigid hammer toes. A rigid hammer toe is one with a rigid toe joint, one that is not moveable with your finger. These rigid toe joints can be very painful and limit the ability to move.
Causes
Hammer toe is often caused by wearing shoes that do not fit properly. If shoes are too small either in length or width, then the toes are held in a shortened position for long periods and the muscles eventually shorten and pull the toes into the bent position. Alternatively it can be caused by overactivity in the extensor digitorum dongus muscle (right) and a weakness in the counteracting muscle under the foot, such as flexor digitorum longus. Sometimes it can be a congenital condition, meaning it is present from birth. It is also more common in those with arthritis in the foot or diabetes.
Symptoms
The symptoms of hammertoe are progressive, meaning that they get worse over time. Hammertoe causes the middle joint on the second, third, fourth, or fifth toes to bend. The affected toe may be painful or irritated, especially when you wear shoes. Areas of thickened skin (corns) may develop between, on top of, or at the end of your toes. Thickened skin (calluses) may also appear on the bottom of your toe or the ball of your foot. It may be difficult to find a pair of shoes that is comfortable to wear.
Diagnosis
Most health care professionals can diagnose hammertoe simply by examining your toes and feet. X-rays of the feet are not needed to diagnose hammertoe, but they may be useful to look for signs of some types of arthritis (such as rheumatoid arthritis) or other disorders that can cause hammertoe.
Non Surgical Treatment
Wear wide shoes with plenty of room in the toes and resilient soles. Avoid wearing shoes with pointed toes. Commercially available felt pads or cushions may ease pressure from the shoe on the toe. Toe caps (small, padded sleeves that fit around the tip of the toe) may relieve the pain of hammer toe. Do toe exercises, to help toe muscles become stronger and more flexible.Arch supports or an orthotic shoe insert prescribed by your doctor or podiatrist may help to redistribute weight on the foot. These devices do not cure the problem but may ease the symptoms of either hammer toe or mallet toe.
Surgical Treatment
Ordinary hammertoe procedures often use exposed wires which extend outside the end of toes for 4-6 weeks. Common problems associated with wires include infection where the wires come out of the toe, breakage, pain from hitting the wire, and lack of rotational stability causing the toe to look crooked. In addition, wires require a second in-office procedure to remove them, which can cause a lot of anxiety for many patients. Once inserted, implants remain within the bone, correcting the pain and deformity of hammertoes while eliminating many of the complications specific traditional treatments.
