OverviewHammer toe a bending and hardening of the joints of the second, third, fourth, or fifth toes. If you look down at your feet and you can?t see the tips of the toenails, you might suffer from hammertoe. Early signs of hammertoe are a bend in the joint of any toe except the big toe. The bend in the joint causes the top of the toe to appear to curl under as if it?s ?hammering? into the floor.
Causes
The most common cause of hammertoe is a muscle/tendon imbalance. This imbalance, which leads to a bending of the toe, results from mechanical (structural) changes in the foot that occur over time in some people. Hammertoes may be aggravated by shoes that don?t fit properly. A hammertoe may result if a toe Hammer toes is too long and is forced into a cramped position when a tight shoe is worn. Occasionally, hammertoe is the result of an earlier trauma to the toe. In some people, hammertoes are inherited.
SymptomsThe 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
Hammer toes may be easily detected through observation. The malformation of the person's toes begin as mild distortions, yet may worsen over time - especially if the factors causing the hammer toes are not eased or removed. If the condition is paid attention to early enough, the person's toes may not be permanently damaged and may be treated without having to receive surgical intervention. If the person's toes remain untreated for too long, however the muscles within the toes might stiffen even more and will require invasive procedures to correct the deformity.
Non Surgical Treatment
Apply a commercial, nonmedicated hammertoe pad around the bony prominence of the hammertoe. This will decrease pressure on the area. Wear a shoe with a deep toe box. If the hammertoe becomes inflamed and painful, apply ice packs several times a day to reduce swelling. Avoid heels more than two inches tall. A loose-fitting pair of shoes can also help protect the foot while reducing pressure on the affected toe, making walking a little easier until a visit to your podiatrist can be arranged. It is important to remember that, while this treatment will make the hammertoe feel better, it does not cure the condition. A trip to the podiatric physician?s office will be necessary to repair the toe to allow for normal foot function. Avoid wearing shoes that are too tight or narrow. Children should have their shoes properly fitted on a regular basis, as their feet can often outgrow their shoes rapidly. See your podiatric physician if pain persists.
Surgical Treatment
The deformity is corrected in a variety of ways. There are actually a large number of procedures. The simplest procedure would involve a Tenotomy, the cutting of the tendon causing the deformity or a Tendon Lengthening procedure. These procedures are infrequently done, though, as the structural deformity (the arthritis and joint adaptation) is not addressed with these surgeries. Other soft-tissue procedures involve rebalancing the tendons around the joint. There are several techniques to do this, but the most common is probably the Girdlestone-Taylor procedure, which involves rerouting the tendons on the bottom of the toe up and over the toe where it sticks up, so that the tendon helps pull the toe downwards into proper alignment.
Causes As discussed above, many different problems can create a painful flatfoot. Damage to the posterior tibial tendon is the most common cause of AAFD. The posterior tibial tendon is one of the most important tendons of the leg. It starts at a muscle in the calf, travels down the inside of the lower leg and attaches to the bones on the inside of the foot. The main function of this tendon is to support the arch of your foot when you walk. If the tendon becomes inflamed or torn, the arch will slowly collapse. Women and people over 40 are more likely to develop problems with the posterior tibial tendon. Other risk factors include obesity, diabetes, and hypertension. Having flat feet since childhood increases the risk of developing a tear in the posterior tibial tendon. In addition, people who are involved in high impact sports, such as basketball, tennis, or soccer, may have tears of the tendon from repetitive use. Inflammatory arthritis, such as rheumatoid arthritis, can cause a painful flatfoot. This type of arthritis attacks not only the cartilage in the joints, but also the ligaments that support the foot. Inflammatory arthritis not only causes pain, but also causes the foot to change shape and become flat. The arthritis can affect the back of the foot or the middle of foot, both of which can result in a fallen arch. An injury to the tendons or ligaments in the foot can cause the joints to fall out of alignment. The ligaments support the bones and prevent them from moving. If the ligaments are torn, the foot will become flat and painful. This more commonly occurs in the middle of the foot (Lisfranc injury), but can also occur in the back of the foot. Injuries to tendons of the foot can occur either in one instance (traumatically) or with repeated use over time (overuse injury). Regardless of the cause, if tendon function is altered, the forces that are transmitted across joints in the foot are changed and this can lead to increased stress on joint cartilage and ligaments. In addition to tendon and ligament injuries, fractures and dislocations of the bones in the midfoot can also lead to a flatfoot deformity. People with diabetes or with nerve problems that limits normal feeling in the feet, can have collapse of the arch or of the entire foot. This type of arch collapse is typically more severe than that seen in patients with normal feeling in their feet. In addition to the ligaments not holding the bones in place, the bones themselves can sometimes fracture and disintegrate without the patient feeling any pain. This may result in a severely deformed foot that is very challenging to correct with surgery. Special shoes or braces are the best method for dealing with this problem. Symptoms Symptoms of pain may have developed gradually as result of overuse or they may be traced to one minor injury. Typically, the pain localizes to the inside (medial) aspect of the ankle, under the medial malleolus. However, some patients will also experience pain over the outside (lateral) aspect of the hindfoot because of the displacement of the calcaneus impinging with the lateral malleolus. This usually occurs later in the course of the condition. Patients may walk with a limp or in advanced cases be disabled due to pain. They may also have noticed worsening of their flatfoot deformity. Diagnosis In diagnosing flatfoot, the foot & Ankle surgeon examines the foot and observes how it looks when you stand and sit. Weight bearing x-rays are used to determine the severity of the disorder. Advanced imaging, such as magnetic resonance imaging (MRI) and computed tomography (CAT or CT) scans may be used to assess different ligaments, tendons and joint/cartilage damage. The foot & Ankle Institute has three extremity MRI?s on site at our Des Plaines, Highland Park, and Lincoln Park locations. These extremity MRI?s only take about 30 minutes for the study and only requires the patient put their foot into a painless machine avoiding the uncomfortable Claustrophobia that some MRI devices create. Non surgical Treatment Treatment depends very much upon a patient?s symptoms, functional goals, degree and specifics of deformity, and the presence of arthritis. Some patients get better without surgery. Rest and immobilization, orthotics, braces and physical therapy all may be appropriate. With early-stage disease that involves pain along the tendon, immobilization with a boot for a period of time can relieve stress on the tendon and reduce the inflammation and pain. Once these symptoms have resolved, patients are often transitioned into an orthotic that supports the inside aspect of the hindfoot. For patients with more significant deformity, a larger ankle brace may be necessary. 
Surgical Treatment The indications for surgery are persistent pain and/or significant deformity. Sometimes the foot just feels weak and the assessment of deformity is best done by a foot and ankle specialist. If surgery is appropriate, a combination of soft tissue and bony procedures may be considered to correct alignment and support the medial arch, taking strain off failing ligaments. Depending upon the tissues involved and extent of deformity, the foot and ankle specialist will determine the necessary combination of procedures. Surgical procedures may include a medial slide calcaneal osteotomy to correct position of the heel, a lateral column lengthening to correct position in the midfoot and a medial cuneiform osteotomy or first metatarsal-tarsal fusion to correct elevation of the medial forefoot. The posterior tibial tendon may be reconstructed with a tendon transfer. In severe cases (stage III), the reconstruction may include fusion of the hind foot,, resulting in stiffness of the hind foot but the desired pain relief. In the most severe stage (stage IV), the deltoid ligament on the inside of the ankle fails, resulting in the deformity in the ankle. This deformity over time can result in arthritis in the ankle.
