Common Disorders:

Description of the Condition

One of the more common conditions treated by podiatric surgeons is the painful bunion. Patients with this condition will usually complain of pain when wearing certain shoes, especially snug fitting dress shoes, or with physical activity, such as walking or running. Bunions are most commonly treated by conservative means. This may involve shoe gear modification, padding and orthoses. When this fails to provide adequate relief, surgery is often recommended. There are several surgical procedures to correct bunions. Selection of the most appropriate procedure for each patient requires knowledge of the level of deformity, review of the x-rays and an open discussion of the goals of the surgical procedure. Almost all surgical procedures require cutting and repositioning the first metatarsal. In the case of mild to moderate bunion deformities the bone cut is most often performed at the neck of the metatarsal (near the joint).

Cause of Bunion Deformity

The classic bunion, medically known as hallux abductovalgus or HAV, is a bump on the side of the great toe joint. This bump represents an actual deviation of the 1st metatarsal and often an overgrowth of bone on the metatarsal head. In addition, there is also deviation of the great toe toward the second toe. In severe cases, the great toe can either lie above or below the second toe. Shoes are often blamed for creating these problems. This, however, is inaccurate. It has been noted that primitive tribes where going barefoot is the norm will also develop bunions. Bunions develop from abnormal foot structure and mechanics (e.g. excessive pronation), which place an undue load on the 1st metatarsal. This leads to stretching of supporting soft tissue structures such as joint capsules and ligaments with the end result being gradual deviation of the 1st metatarsal. As the deformity increases, there is an abnormal pull of certain tendons, which leads to the drifting of the great toe toward the 2nd toe. At this stage, there is also adaptation of the joint itself that occurs.

Symptoms Related to Bunion Deformity

The most common symptoms associated with this condition are pain on the side of the foot. Shoes will typically aggravate bunions. Stiff leather shoes or shoes with a tapered toe box are the prime offenders. This is why bunion pain is most common in women whose shoes have a pointed toe box. The bunion site will often be slightly swollen and red from the constant rubbing and irritation of a shoe. Occasionally, corns can develop between the 1st and 2nd toe from the pressure the toes rubbing against each other. On rare occasions, the joint itself can be acutely inflamed from the development of a sac of fluid over the bunion called a bursa. This is designed to protect and cushion the bone. However, it can become acutely inflamed, a condition referred to as bursitis.

Treatment of Bunion Deformity

Early treatment of bunions is centered on providing symptomatic relief. Switching to a shoe with a rounder, deeper toe box and made of a softer more pliable leather will often provide immediate relief. The use of pads and cushions to reduce the pressure over the bone can also be helpful for mild bunion deformities. Functional foot orthotics, by controlling abnormal pronation, reduces the deforming forces leading to bunions in the first place. These may help reduce pain in mild bunion deformities and slow the progression of the deformity. When these conservative measures fail to provided adequate relief, surgical correction is indicated. The choice of surgical procedures (bunionectomy) is based on a biomechanical and radiographic examination of the foot. Because there is actual bone displacement and joint adaptation, most successful bunionectomies require cutting and realigning the 1st metatarsal (an osteotomy). Simply “shaving the bump” is often inadequate in providing long-term relief of symptoms and in some cases can actually cause the bunion to progress faster. The most common procedure performed for the correction of bunions is the 1st metatarsal neck osteotomy, near the level of the joint. This refers to the anatomical site on the 1st metatarsal where the actual bone cut is made. Other procedures are preformed in the shaft of the metatarsal bone and still other procedures are selected by the surgeon that is performed in the base of the metatarsal bone.

Description

Corns and calluses are areas of thick skin that result form excessive pressure or friction over a boney prominence. When these areas develop on the bottom of the foot they are called calluses. When they occur on the top of the toes they are called corns. They can also occur between the toes, the back of the heels and the top of the foot. The thickening of the skin is a normal body response to pressure or friction. Often times they are associated with a projection of bone called a bone spur. Not all areas of thickened skin are corns or calluses. Planter's warts, inclusion cysts and porokeratoses also cause a discreet thickening of the skin that resembles corns and calluses.

Calluses

The most common area for the formation of calluses on the bottom of the foot is in the area of the ball of the foot. This is a weight bearing area where the long bones behind the toes called metatarsals, bear the greatest amount of weight and pressure. If one or more of these long bones (metatarsals) is out of alignment then excessive pressure is generated in the area producing a callous. The callused area can be very discreet and have a "core" or they can be more dispersed covering a larger area. These areas can become quite painful as the skin thickens. People who have diabetes are at risk of these areas breaking down producing sores or ulcerations that can become infected. People with diabetes should not try home remedies and should see a doctor for the treatment.

Treatment of Calluses

There are numerous over the counter treatments for corns and calluses. Some of these remedies have an acid in them that burn the callous off. Care should be taken when using these medications. If used incorrectly they can cause a chemical burn to the skin. Additionally these remedies are only temporary because the source of the pressure has not been alleviated. Professional treatment consists of using a special shoe insert called a functional orthotic that corrects foot function. In certain instances surgery may be recommended. Surgery is directed at correcting the alignment of the offending bone. Cutting out the callous will only make the condition worse if the underling boney problem is not corrected. Metatarsal surgery is discussed in another section.

Corns

Corns are areas of thick skin that most commonly occur on the top of the toes. Generally there is an associated hammertoe deformity, which causes the toes to rub on the top of the shoes. Professional treatment is directed at correcting the hammertoe deformity. Small corns can also occur on the side of the little toe next to the toenail. A small bone spur causes this problem. Professional treatment consists of removing the bone spur. Bone spurs also cause corns between the toes.

Soft corns are areas of white moist skin between the toes. They most commonly occur between the fourth and fifth toes. They can be very painful and if not treated can form small ulcerations or sinus tracts that can become infected. Acute athlete's foot can mimic the soft corn. The soft corn is due to an irregularity in the shape of the bone in the fourth or fifth toes.

Treatment of Corns

Home treatment should be directed at reducing the pressure between the toes with cotton or a foam cushion and using an antibiotic ointment to reduce the risk of infection. Over the counter corn removers should never be used in this area because of the risk of increased damage to the skin resulting in infection. Professional treatment consists of removing the irregular shaped bone that causes the development of the corn. Some patients prefer that the doctor simply trim down and pad the calloused areas. This is a common form of treatment in patients with diabetes.

Peripheral Neuropathy is a nerve condition that affects the arms, hands, legs, and feet. The most common form of peripheral neuropathy is due to diabetes.

Diabetic Peripheral Neuropathy

People with diabetes have an abnormal elevation of their blood sugar, and lack adequate insulin to metabolize the blood sugar. As a consequence, the blood glucose (sugar) abnormally enters certain nerve tissue and damages the nerve. This can occur in any type of diabetes. It does not matter if the patient is on insulin, is taking pills, or is diet controlled. The nerve damage that occurs is considered to be permanent.

As the nerve damage occurs, the protective sensations are affected. These include a person’s ability to determine the difference between sharp and dull, hot and cold, pressure differences, and vibration. These senses become dulled and/or altered. The process begins as a burning sensation in the toes and progresses up the foot in a "stocking distribution". As the condition progresses, the feet become more and more numb. Some people will feel as though a pair of socks on their feet, when in fact they do not. Other patients will describe the feeling of walking on cotton, or a water-filled cushion. Some patients complain of their feet burn at night, making it difficult to sleep. The feet may also feel like they are cold, however, to the touch, they have normal skin temperature. Diabetic peripheral neuropathy is not reversible. The progression of the condition can be slowed or halted by maintaining normal blood glucose levels.

As the patient develops diabetic neuropathy, they have a greater risk of developing skin ulcerations and infections. Areas of corns and callouses on the feet represent areas of excessive friction or pressure. These areas, if not properly cared for by a foot specialist, will often break down and cause ulcerations. Ulcerations and infection can form under the calloused area. These calloused areas may not be painful. As a result, they can progress to ulceration without being noticed. Ingrown toenails can progress to severe infections in people with neuropathy. Simple things like trimming the toenails present a risk to these patients because they may accidentally cut the skin and not feel it. People with neuropathy must be very cautious and inspect their feet daily. They should not soak their feet in hot water or use heating pads to warm their feet. This can result in accidental burns to the skin. Barefoot walking should be avoided because of the risk of stepping on something sharp and not being aware of it. The inside of the shoes should be inspected before putting the shoes on to insure that no foreign object is inside the shoe.

Our office is equipped with a machine called the Doppler. This exam measures the vascular blood flow in the foot and ankle through a non-invasive procedure. Like a sonogram, a gel is spread over the ankle and foot, and the doctor can assess the blood flow by computer readout. The test is quick, easy, and accurate.

Alcoholic Peripheral Neuropathy

Alcoholic neuropathy is caused by the prolonged use of alcoholic beverages. Ethanol, the alcoholic component of these beverages, is toxic to nerve tissue. Over time, the nerves in the feet and hands can become damaged resulting in the same loss of sensation as that seen in diabetic neuropathy. The damage to these nerves is permanent. A person with this condition is at the same risk, and should take the same precautions as people with diabetic peripheral neuropathy. Peripheral neuropathy can also be caused by exposure to toxins such as pesticides and heavy metals.

Treatment For Peripheral Neuropathy

Patients diagnosed with diabetes mellitus should also consider having specially made shoes to protect their feet. Most patients with diabetes qualify for footwear and inserts under the Medicare Therapeutic Shoe Bill. Medicare covers patients for one pair of shoes and three inserts per year. Our office has partnered with Orthofeet shoes which offer a proper fitting for the diabetic patient with extra width across the midfoot and ample room at the toe-box to avoid pressure. These shoes are also designed to accommodate orthotics.

Ulcerations, infections and gangrene are the most common foot and ankle problems that the patient with diabetes must face. As a result, thousands of diabetic patients require amputations each year. Foot infections are the most common reason for hospitalization of diabetic patients. Ulcerations of the feet may take months or even years to heal. It takes 20 times more energy to heal a wound than to maintain a healthy foot.

There are two major causes of foot problems in diabetes:

1. Nerve Damage (neuropathy): This causes loss of feeling in the foot, which normally protects the foot from injury. The protective sensations of sharp/dull, hot /cold, pressure and vibration become altered or lost completely. Furthermore, nerve damage causes toe deformities, collapse of the arch, and dry skin. These problems may result in foot ulcers and infections, which may progress rapidly to gangrene and amputation. However: Daily foot care and regular visits to the podiatrist can prevent ulcerations and infections.



2. Loss of circulation (angiopathy): Poor circulation may be difficult to treat. If circulation is poor gangrene and amputation may be unavoidable. Cigarette smoking should be avoided. Smoking can significantly reduce the circulation to the feet significantly. There are certain medications available for improving circulation (Trental) and by-pass surgery may be necessary to improve circulation to the feet. Chelation therapy is an alternative form of treatment for circulatory problems that is not well recognized by the medical community at large. Daily foot care and regular visits to the podiatrist can often prevent or delay the need for amputation.

Prevention:

Do the Following to Protect Your Feet

1. Examine Your Feet Daily

1. Use your eyes and hands, or have a family member help.
2. Check between your toes.
3. Use a mirror to observe the bottom of your feet.
4. Look for these Danger Signs:


Swelling (especially new, increased or involving one foot)
Redness (may be a sign of a pressure sore or infection)
Blisters (may be a sign of rubbing or pressure sore)
Cuts or Scratches or Bleeding (may become infected)
Nail Problems (may rub on skin, cause ulceration or become infected)
Maceration, Drainage (between toes)

If you observe any of these danger signs, call your podiatrist at once.

2. Examine Your Shoes Daily

1. Check the insides of your shoes, using your hands, for:
Irregularities (rough areas, seams)
Foreign Objects (stones, tacks)

3. Daily Washing and Foot Care

1. Wash your feet daily.
2. Avoid water that is too hot or too cold. Use lukewarm water.
3. Dry off the feet after washing, especially between the toes.
4. If your skin is dry, use a small amount of lubricant on the skin.
5. Use lambs wool (Not cotton) between the toes to keep these areas dry.

4. Fitting Shoes and Socks

1. Make sure that the shoes and socks are not to tight
2. The toe box of the shoe should have extra room and be mace of a soft upper material that can "breath"
3. New shoes should be removed after 5-10 minutes to check for redness, which could be a sign of too much pressure: if there is redness, do not wear the shoe. If there is no redness, check again after each half hour during the first day of use.
4. Rotate your shoes
5. Ask your podiatrist about therapeutic (prescription) footwear, which is a covered benefit for diabetic patients in many insurance plans.
6. Tell your shoe salesman that you have diabetes.

5. Medical Care

1. See your podiatrist on a regular basis
2. Ask your primary care doctor to check your feet on every visit.
3. Call your doctor if you observe any of the above danger signs.

Do Not Do These Dangerous Acts

• Do Not Walk Barefoot - Sharp objects or rough surfaces can cause cuts, blisters, and other injuries.
• Do Not Use Heat on the Feet - Heat can cause a serious burn, especially if the patient has neuropathy.
• Do Not Apply a Heating Pad to the Feet
• Do Not Soak Your Feet in Hot Water
• Do Not Use Chemicals or Sharp Instruments to Trim Calluses - This could cause cuts and blisters that may become infected.
• Do Not Cut Nails into the Corners - cut nails straight across.
• Do Not Smoke - smoking reduces the circulation to your feet.

Description

The most common cause of yellowed, thick and/or deformed toenails is a fungal infection of the toenail. The fungus that infects the nail, most commonly, is the same fungus that causes athletes foot. It tends to be slowly progressive, damaging the nail to a greater and greater degree over time. The infection usually starts at the tip of the nail and works its way back. It usually is not painful and often not noticed until it has gotten well established. A single toenail or any number of nails can be affected. It can also occur on just one foot. Over time, the nail becomes thickened, crumbly, and distorted in appearance. Sweaty feet contribute to the initial infection process and contribute to its spread. The fungus prefers an environment that is moist, dark and warm, which is why it affects the toenails much more often than fingernails. It does not spread through the blood stream. The infection limits itself to the nails and skin. It is often found in association with areas of dry scaly skin on the bottom of the foot or between the toes. The dry scaling skin is frequently found to be chronic athletes' foot. It is not highly contagious, and family members are almost as likely to contract it from some other source as they are from the family member who has the infection. Keeping common showering areas clean is recommended, and sharing shoes should be avoided.

Diagnosis

Not all thicken or yellowed toenails are caused by a fungal infection. Injury to a toenail can cause the toenail to grow in a thickened or malformed fashion. This can be due to an established fungal infection or may be due to the damage caused to the nail root when it was injured. In these instances, treatment with anti-fungal medications will not correct the malformed nail. Other causes of thickened toenails are small bone spurs that can form under the toenail and psoriasis. Taking a scraping of the toenail and culturing it makes the diagnosis.

Treatment

It is best to treat the condition as soon as it is noticed. In early cases, over the counter medications may be sufficient. It is also important to treat any concomitant athlete’s foot that may be present. In more advanced cases, a prescription medication may be needed. There are effective topical and oral medications available for the treatment of fungal toenails. If sweating feet are a problem, changing shoes and socks during the day is recommended. There are some topical medications available that help to reduce the sweating of the feet. On occasion, your doctor may recommend removing the toenail.

Description

Ulcerations are a result of a break down of the skin. Ulcerations are classified based upon their depth and their cause. Common ulcerations are due to diabetes, ischemia (poor circulation),and venous stasis(varicose veins).

Diabetic ulcerations are by far the most common form of ulceration of the feet. These ulcerations occur in areas of the foot that are exposed to excessive pressure or irritation from the rubbing of the shoes on the skin. corns and calluses develop as a result of excessive pressure over bony areas of the foot. Over time the thickened callous that forms can act as an irritant that breaks down the skin under the callous, forming an ulceration. This is more likely to occur if the person with diabetes also suffers from diabetic neuropathy. Diabetic neuropathy is a condition that most commonly affects the nerves of the hands and feet. Diabetic neuropathy causes a loss or alteration in the ability to perceive pain associated with excessive pressure, heat or cold, sharp and dull, vibration and position sense. As a consequence, corns and calluses which would normally be painful do not cause pain and over time, breaks down the skin causing ulceration. Quite often, an infection will also occur which can result in bone infection (osteomyolytis) or deep tissue infection. If the person also has poor circulation, gangrene can develop.

Treatment is geared toward prevention. People with diabetes must learn to inspect their feet daily and obtain medical attention as soon as they notice anything suspicious or an ulceration forming. Calluses which have a black or blue appearance are in the early stages of ulceration. Corns and calluses should be treated regularly by a podiatrist. These areas should be protected from pressure by using pads and/or cushions.

Over-the-counter corns removers must be avoided. These home treatments have acid in them, which can burn the skin and cause infection. Once an ulceration has started, every effort must be made to reduce the pressure to the area or it will not heal. Special shoe inserts, called orthotics, are useful in reducing abnormal pressure on the bottom of the foot in areas of calluses or ulcerations. There are also several different topical medications that are used for the treatment of ulcerations. Treatment should be guided and supervised by a physician.

Ischemic ulcerations occur in areas of poor circulation. Commonly they form on the feet, ankles and lower legs. As the circulation gets worse, the skin begins to thin and is less resistant to pressure and friction forces. Spontaneous break down of the skin can occur. These ulcerations tend to be painful, with a whitish or light-pinkish base. Treatment is focused on keeping the ulceration clean and free from infection. By-pass surgery may be indicated to improve the circulation to the area. Hyperbaric oxygen treatments may also be useful. It is important not to use bandages that can cut off the circulation, or adhesive tape, which can tear the skin when removed.

Venous stasis ulcerations occur in areas where the venous circulation is poor. Venous circulation is the blood flow that returns to the heart in the veins. Varicose veins are abnormal veins that do not allow normal blood flow back to the heart. As the veins become more and more damaged, there is a pooling of fluid that accumulates in the feet and ankle. This swelling of the tissue, over time will cause damage to the skin, and can result in open sores or ulceration. These ulcerations tend to weep a clear fluid, have a reddish base and become infected easily.

Treatment is geared toward prevention by reducing the swelling in the legs with the use of support stockings, medications to reduce the swelling, and elevation of the legs. Once ulcerations have developed, treatment consists of keeping the ulcerations clean and free from infection. This often requires the long-term use of oral antibiotics. A common form of treatment consists of wrapping the legs with a dressing called an unna boot. This dressing is a gauze wrap which has xinc oxide impregnated in it. This dressing helps to keep the bacteria that is in the ulceration from growing and also adds compression to help reduce swelling.

Description

Hammertoes are a contracture of the toes as a result of a muscle imbalance between the tendons on the top and the tendons on the bottom of the toe. They can be flexible or rigid in nature. When they are rigid, it is not possible to straighten the toe out by manipulating it. Frequently, they develop corns on the top of the toe as a result of rubbing on the shoe. They may also cause a bothersome callous on the ball of the foot. This occurs as a result of the toe pressing downward on the bone behind the toe. This area then becomes prominent and the pressure of the bone against the ground causes a callous to form.

They tend to slowly get worse with time and frequently flexible deformities become rigid. Treatment can be preventative, symptomatic or curative.

Preventative treatment of hammertoe is directed toward the cause of the deformity. A functional orthotic is a special insert that can be prescribed by your podiatrist to address the abnormal functioning of the foot that causes the hammertoe. Functional orthotics can be thought of as contact lenses for your feet. They correct a number of foot problems that are caused by an abnormally functioning foot. Our feet, much like our eyes, change with time. Functional orthotics slow down or halt this gradual change in the foot. Often when orthotics are used for flexible hammertoes, the toes will overtime straighten out and correct themselves. Calf stretching exercises are also helpful. Calf stretching can help to overcome part of the muscle imbalance that causes the hammertoe.

Symptomatic treatment of hammertoes consists of such things as open toed shoes or hammertoe pads. There are over the counter corn removers for temporally reducing the painful callous often seen with the hammertoe. These medications must be used with caution. They are a mild acid that burns the callous off. These medications should never be used for corns or callouses between the toes. Persons with diabetes or bad circulation should never use these products.

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. For the surgical correction of a rigid hammertoe, the surgical procedure consists of removing the damaged skin where the corn is located. Then a small section of bone is removed at the level of the rigid joint. The sutures remain in place for approximately ten days. During this period of time it is important to keep the area dry. Most surgeons prefer to leave the bandage in place until the patient’s follow-up visit, so there is no need for the patient to change the bandages at home. The patient is returned to a stiff-soled walking shoe in about two weeks. It is important to try and stay off the foot as much as possible during this time. Excessive swelling of the toe is the most common patient complaint. In severe cases of hammertoe deformity a pin may be required to hold the toe in place and the surgeon may elect to fuse the bones in the toe. This requires several weeks of recovery.

Complications associated with the surgery are infection, excessive swelling leading to delays in healing and potential deviation of the toe. If excessive bone is removed during the surgery, the toe may be a bit floppy. The toe always has a floppy feeling for several weeks following the surgery. This is normal and generally not permanent.

If pinning the toe is not required during the procedure, then the surgery could be preformed in the doctor’s office under a local anesthesia. Some patients prefer the comfort of sedation during the surgery and if this is the case or if a pin must be placed, then the surgery could be preformed in an outpatient surgery center.

Description

The most common form of heel pain, is pain on the bottom of the heel. It tends to occur for no apparent reason and is often worse when first placing weight on the foot. Patients often complain of pain the first thing in the morning or after getting up to stand after sitting. The pain can be a sharp, searing pain or present as a tearing feeling in the bottom of the heel. As the condition progresses there may be a throbbing pain after getting off your feet or there may be soreness that radiates up the back of the leg. Pain may also radiate into the arch of the foot.

To understand the cause of the pain one must understand the anatomy of the foot and some basic mechanics in the function of the foot. A thick ligament, called the plantar fascia, is attached into the bottom of the heel and fans out into the ball of the foot, attaching into the base of the toes. The plantar fascia is made of dense, fibrous connective tissue that will stretch very little. It acts something like a shock absorber. As the foot impacts the ground with each step, it flattens out lengthening the foot. This action pulls on the plantar fascia, which stretches slightly. When the heel comes off the ground the tension on the ligament is released. Anything that causes the foot to flatten excessively will cause the plantar fascia to stretch greater than it is accustom to doing. One consequence of this is the development of small tears where the ligament attaches into the heel bone. When these small tears occur, a very small amount of bleeding occurs and the tension of the plantar fascia on the heel bone causes a spur on the bottom of the heel to form. Pain experienced in the bottom of the heel is not produced by the presence of the spur. The pain is due to excessive tension of the plantar fascia as it tears from its attachment into the heel bone. Heel spur formation is secondary to the excessive pull of the plantar fascia where it attaches to the heel bone. Many people have heel spurs at the attachment of the plantar fascia without having any symptoms or pain. There are some less common causes of heel pain but they are relatively uncommon.

There are several factors that cause the foot to flatten and excessively stretching the plantar fascia. The primary factor is the structure of a joint complex below the ankle joint, called the subtalar joint. The movement of this joint complex causes the arch of the foot to flatten and to heighten. Flattening of the arch of the foot is termed pronation and heightening of the arch is called supination. If there is excessive pronation of the foot during walking and standing, the plantar fascia is strained. Over time, this will cause a weakening of the ligament where it attaches into the heel bone. When a person is at rest and off of their feet, the plantar fascia attempts to mend itself. Then, with the first few steps the fascia re-tears causing pain. Generally after the first few steps, the pain diminishes. This is why the heel pain tends to be worse the first few steps in the morning or after rest. Another cause of heel pain is compression of the calcaneal nerve and may be diagnosed thru neuro sensory motor testing.

One other factor that contributes to the flattening of the arch of the foot is tightness of the calf muscles. The calf muscle attaches into the foot by the achilles tendon into the back of the heel. When the calf muscle is tight it limits the movement of the ankle joint. When ankle joint motion is limited by the tightness of the calf muscle it forces the subtalar joint to pronate excessively. Excessive subtalar joint pronation can cause several different problems to occur in the foot. In this instance, it results in excessive tension of the plantar fascia. Tightness of the calf muscles can be a result of several different factors. Exercise, such as walking or jogging will cause the calf muscle to tighten. Inactivity or prolonged rest will also cause the calf muscle to tighten. Women who wear high heels and men who wear western style cowboy boots will, over time, develop tightness in the calf muscles.

Diagnosis

The diagnosis of heel pain and heel spurs is made by a through history of the course of the condition and by physical exam. Weight bearing x-rays are useful in determining if a heel spur is present and to rule out rare causes of heel pain such as a stress fracture of the heel bone, the presence of bone tumors or evidence of soft tissue damage caused by certain connective tissue disorders.

Treatment

Treatment of heel pain generally occurs in stages. At the earliest sign of heel pain, aggressive calf muscle stretching should be started. Additionally, taking an oral anti-inflammatory medication and over-the- counter arch supports or heel cushions may be beneficial.

The next phase of treatment might consist of continued calf muscle stretching exercises, cortisone injections and orthopedic taping of the foot to support the arch. If this treatment fails, or if there is reoccurrence of the heel pain, then functional foot orthotics might be considered. A functional orthotic is a device that is prescribed and fitted by your foot doctor, which fits in normal shoes like an arch support. Unlike an arch support, however the orthotic corrects abnormal pronation of the subtalar joint. Thus orthotics address the cause of the heel pain - abnormal pronation of the foot.

The doctors at the Foot and Ankle Center are excited to also offer a new treatment, Extracorporeal Shock Wave Therapy, for chronic plantar fasciitis "heel pain". Extracorporeal" means "outside the body". Shock waves are created by very strong acoustic (sound) energy. Your ESW treatment will be performed with a device called the OssaTron. The OssaTron is a shock wave generator very similar to the shock wave devices used to treat kidney stones without surgery. The shock waves are created by a spark plus that is enclosed in a soft plastic dome filled with water. During ESW treatment, this dome is placed close against the heel so that the shock waves pass through the dome to the heel. ESW treatment has recently been found to be effective for treating chronic proximal plantar fasciitis.

Surgery to correct heel pain is generally only recommended if orthotics or the OssaTron treatment have not been successful. A new endoscopic treatment for heel pain is now available from Foot and Ankle Center of North Houston. This new method uses an endoscope which is a small camera instrument that allows the surgeon to see "anatomy" inside the body. By using a very small incision, less than ½ inch, this new procedure releases the extreme tension on the plantar fascia which is the cause of the pain in the majority of cases. All of this is viewed on the television monitor by the surgeon. The procedure itself usually takes less than 10 minutes using a local anesthetic. A sterile dressing is worn for approximately 3 days and then the patient is usually allowed to return to regular shoe wear. Minimal loss of work is incurred.

There are some exceptions to this course of treatment and it is up to you and our office to determine the most appropriate course of treatment. Following surgical treatment to correct heel pain the patient will generally have to continue the use of orthotics. The surgery does not correct the cause of the heel pain. The surgery will illuminate the pain but the process that caused the pain will continue without the use of orthotics. If orthotics have been prescribed prior to surgery they generally do not have to be remade.

Description

Ingrown toenails are due to the penetration of the edges of the nail plate into the soft tissue of the toe. It begins with a painful irritation that often becomes infected. With bacterial invasion, the nail margin becomes red and swollen often demonstrating drainage or pus. In people who have diabetes or poor circulation this relatively minor problem can be become quite severe. In this instance a simple ingrown toenail can result in gangrene of the toe. These patients should seek medical attention at the earliest sign of an ingrown toenail. There are several causes of ingrown toenails: a hereditary tendency to form ingrown toenails, improperly cutting the toenails either too short or cutting into the side of the nail and ill-fitting shoes can cause them. Children will often develop ingrown toenails as a result of pealing or tearing their toenails off instead of trimming them with a nail clipper. Once an ingrown toenail starts, they will often reoccur. Many people perform "bathroom" surgery to cut the nail margin out only to have it reoccur months later as the nail grows out.

Treatment

Treatment for ingrown toenails is relatively painless. The injection to numb the toe may hurt some, but a skilled doctor has techniques to minimize this discomfort. Once the toe is numb, the nail margin is removed and the nail root in this area is destroyed. The doctor may use an acid to kill the root of the nail, but other techniques are also available. It may take a few weeks for the nail margin to completely heal, but there are generally no restrictions in activity, bathing or wearing shoes. Once the numbness wears off, there may be some very mild discomfort. A resumption of sports activities and exercise is generally permitted. There are very few complications associated with this procedure. Reoccurrence of the ingrown toenail can occur a small percentage of the time. Continuation of the infection is possible which can be controlled easily with oral antibiotics. On occasion, the remaining nail may become loose from the nail bed and fall off. A new nail will grow out to replace it over several months. With removal of the nail margin, the nail will be narrower and this should be expected.

Description

A neuroma is the swelling of nerve that is a result of a compression or trauma. They are often described as nerve tumors. However, they are not in the purest sense a tumor. They are a swelling within the nerve that may result in permanent nerve damage. The most common site for a neuroma is on the ball of the foot. The most common cause of neuroma in ball of the foot is the abnormal movement of the long bones behind the toes called metatarsal bones. A small nerve passes between the spaces of the metatarsals. At the base of the toes, the nerves split forming a "Y" and enter the toes. It is in this area the nerve gets pinched and swells, forming the neuroma. Burning pain, tingling, and numbness in one or two of the toes is a common symptom. Sometimes this pain can become so severe, it can bring tears to a patient's eyes. Removing the shoe and rubbing the ball of the foot helps to ease the pain. As the nerve swells, it can be felt as a popping sensation when walking. Pain is intermittent and is aggravated by anything that results in further pinching of the nerve. When the neuroma is present in the space between the third and fourth toes, it is called a Morton's Neuroma. This is the most common area for a neuroma to form. Another common area is between the second and third toes. Neuromas can occur in one or both of these areas and in one or both feet at the same time. Neuromas are very rare in the spaces between the big toe and second toe, and between the fourth and fifth toes. Neuromas have been identified in the heel area, resulting in heel pain.

A puncture wound or laceration that injures a nerve can cause a neuroma. These are called traumatic Neuromas. Neuromas can also result following a surgery that may result in the cutting of a nerve.

Diagnosis

The diagnosis of Neuromas is made by a physical exam and a thorough history of the patient's complaint. Conditions that mimic the pain associated with Neuromas are stress fracture of the metatarsals, inflammation of the tendons in the bottom of the toes, arthritis of the joint between the metatarsal bone and the toe, or nerve compression or nerve damage further up on the foot, ankle, knee, hip, or back. X-rays are generally taken to rule out a possible stress fracture or arthritis. Because nerve tissue is not seen on an x-ray, the x-ray will not show the neuroma. A skilled foot specialist will be able to actually feel the neuroma on his exam of the foot. Special studies such as MRI and CT Scan have little value in the diagnosis of a neuroma. However, ultra sound testing has been shown to be very effective in diagnosing neuromas. Neurological testing such as neuro sensory motor testing is also helpful in diagnosing a neuroma. If the doctor on his exam cannot feel the neuroma, and if the patient's symptoms are not what is commonly seen, then nerve compression at another level should be suspected. In this instance, one area to be examined is the ankle.

Just below the ankle bone on the inside of the ankle, a large nerve passes into the foot. At this level, the nerve can become inflamed. This condition is called Tarsal Tunnel Syndrome. Generally, there is not pain at this site of the inflamed nerve at the inside of the ankle. Pain may instead be experienced in the bottom of the foot or in the toes. This can be a difficult diagnosis to make in certain circumstances. Neuromas, however, occur more commonly than Tarsal Tunnel Syndrome.

Treatment

Treatment for the neuroma consists of cortisone injections, orthotics, chemical destruction of the nerve, or surgery. Cortisone injections are generally used as an initial form of treatment. Cortisone is useful when injected around the nerve, because it can shrink the swelling of the nerve. This relieves the pressure on the nerve. Up to three cortisone injections can be given over a twelve-month period. Cortisone may provide relief for many months, but is often not a cure for the condition. The abnormal movements of the metatarsal bones continue to aggravate the condition over a period of time.

To address the abnormal movement of the metatarsal bones, a functional foot orthotic can be used. These devices are custom-made inserts for the shoes that correct abnormal function of the foot. The combination treatment of cortisone injections and orthotics can be a very successful form of treatment. If, however, there is significant damage to the nerve, then failure to this treatment can occur. When there is permanent nerve damage, the patient is left with three choices: live with the pain, chemical destruction of the nerve, or surgical removal of the nerve.

Description

Circulation disorders includes a large number of different problems with one thing in common, they result in poor blood flow. Specifically, the term peripheral vascular disease refers to blood flow impairment into the feet and legs (although it could include the arms and hands as well).

Blood is circulated throughout the human body by the strong, muscular pump called the heart. With each heartbeat, blood is pushed along through blood vessels called arteries that carry the oxygen and nutrient rich blood to all parts of the body including the legs and the feet. The individual cells in the body take up the oxygen and nutrients. Then a second set of blood vessels known as veins carry the oxygen depleted blood back to the heart and lungs to get more oxygen, and again be pumped throughout the body. Peripheral vascular disease may refer to arterial inflow disorders, (arterial insufficiency) or venous outflow disorders (venous insufficiency).

Arterial Insufficiency

Arterial inflow disorders are categorized by the size of the artery involved. If a large artery in the thigh or behind the knee becomes blocked by cholesterol deposits this is referred to as large vessel disease or atherosclerosis. The result may be a painful ischemic foot, which means there is a severe lack of arterial blood flow from the heart into the foot. If smaller arteries like those in the lower leg or foot is blocked, this is referred to as small vessel disease, or arteriosclerosis. This too can result in ischemia of the foot. Small vessel disease is seen more often in diabetics, but can affect non-diabetics as well. If the skin of the feet or legs lacks adequate blood flow a sore will develop which may be difficult to heal. These sores are known as ischemic ulcers. Any blockage to arterial inflow will result in a circulation problem to the body tissues down stream. Occasionally a small blockage will occur in the small arteries that supply blood to a toe. This is known as a "Blue Toe Syndrome." Another arterial inflow problem may result when the smooth muscles that control the size of the arteries go into spasm. The arterial muscle spasm can block the blood from circulating into the foot. One common vasospastic disorder is called Raynaud’s Syndrome. A second vasospastic disorder is called acrocyanosis.

Venous Insufficiency

Venous outflow disorders refer to problems getting blood from the foot back to the heart. There are two sets of veins in the feet and legs to help bring the blood back toward the heart. The superficial venous network refers to veins located just beneath the skin. The deep venous networks are veins located closer to the bones and are not visible when looking at the foot or legs.

Varicose veins refer to an enlargement of the veins and a loss in the ability of the vein to properly maintain blood flow back toward the heart. When this occurs blood can collect in the feet and legs. Superficial varicose veins may appear as unsightly cords or a small bunch of grapes, which usually appear on the tops of the feet, around the ankles and may extend upward to the knees and thighs. Deep varicose veins while usually not visible will result in chronic swelling of the feet, ankles and legs. When the blood is not circulated from the feet back to the heart gravity will cause the fluid to collect in the feet and ankles. This results in swelling, called edema. Chronic edema over a long period of time may cause a discoloration of the skin around the ankles. The skin can become inflamed, and is know as venous stasis dermatitis. If left untreated the skin will become weakened and a weeping sore will develop, usually on the inside of the ankle called a venous stasis ulcer.

A potentially serious consequence of blood collecting in the feet and legs is the formation of blood clots in the veins. A superficial vein blood clot will result in a painful, inflamed superficial vein called superficial phlebitis. When a blood clot forms in a deep vein, it is called deep venous thrombosis, or deep phlebitis. This is a serious condition that causes painful swelling of the leg and may result in part of the clot breaking free. If the clot should travel back up to the heart and get caught in the lungs, it is referred to as a pulmonary embolus which can be life threatening and requires emergency treatment.

Description

The common wart is known as verruca vulgaris. They are caused by a viral infection of the skin. This occurs as a result of direct contact with the virus. They do not spread through the blood stream. They occur more commonly in children than adults. When they occur on the bottom of the foot, they are called plantar warts. This name is derived from the location of the foot on which they are found; the bottom of the foot is called the plantar aspect of the foot. A common misconception is that plantar warts have seeds or roots that grow through the skin and can attach to the bone. The wart may appear to have a root or seeds, but these are in fact small clusters of the wart just beneath the top layer of the skin. The wart cannot live in any tissue except the skin. Moist, sweaty feet can predispose to infection by the wart virus. They can be picked up in showers and around swimming pools. They are not highly contagious, but being exposed in just the right situation will lead to the development of the wart. Avoiding contact in the general environment is nearly impossible. If a member of the family has the infection, care should be taken to keep shower and tile floor clean. Children who have plantar warts should not share their shoes with other people. Young girls often share shoes with their friends and this should be discouraged.

Diagnosis

The warts have the appearance of thick, scaly skin. They can occur as small, single warts or can cluster into large areas. These clustered warts are called mosaic warts. They often resemble plantar calluses. A simple way to tell the difference between a wart and a callous is to squeeze the lesion between your fingers in a pinching fashion. If this is painful, it is likely that the lesion is a wart. A callous is generally not painful with this maneuver but is tender with direct pressure by pressing directly on the lesion. Othe lesions on the bottom of the foot that are often confused with plantars warts are porokeratoses and inclusion cysts.

Treatment

There are a variety of ways to treat warts. The over-the-counter medications have a difficult time penetrating the thick skin on the bottom of the foot, so they do not work well in this area. Professional treatment consists of burning the wart with topical acids, freezing with liquid nitrogen, laser surgery or cutting them out. All methods have the possibility of the wart coming back. Surgical excision of the wart has the highest success rate with a relatively low rate of recurrence. There is some mild discomfort with this procedure and it takes several weeks for the area to completely heal. Normal activity can generally be resumed in a few days depending on the size and number of warts that have been removed. The risks associated with surgical removal of warts are the possibility of infection, or the formation of a scar, which can be painful when weight is applied while walking.

Laser removal of the wart works by burning the wart with a laser beam. The area must be numbed with an anesthetic prior to the procedure. There is little advantage to removing warts with a laser unless the warts are very large (mosaic warts) or there are a large number to be removed. The risks associated with the use of the laser are the same as for cutting the warts out. These risks include infection and the development of a scar after healing. A new type of laser has been developed to treat several different types of skin lesions called the Pulsed Dye Laser. This new laser has promise in the effective treatment of warts.

Freezing the wart with liquid nitrogen is another form of treatment. This form of treatment when the warts are on the bottom of the foot can be very painful and take several days or weeks to heal.

Topical acids can also be a useful means of treating warts. The advantage to this form of treatment is the fact that they are nearly painless and there is no restriction of activity. The down side to this form of treatment is that it frequently requires several treatments and the failure rate is higher than surgical excision of the wart.
