- Multiple SclerosisCharcot joint disease was originally described in patients with tertiary syphilis and absent sensation. However, once penicillin was discovered, the incidence of syphilis dropped dramatically. In general, any disease process that results in loss of sensation in the lower extremity can lead to Charcot joint disease. Today, the leading cause of Charcot joint disease is diabetes mellitus. It is estimated that 1 out of 700 patients with diabetes will develop Charcot joint. Other entities, which can lead to Charcot joint, include: chronic alcoholism, leprosy, hereditary insensitivity to pain, syringomyelia and multiple sclerosis.

- UltrasoundMagnetic Resonance Imaging (MRI) can show tendon injury and inflammation but cannot be relied on with 100% accuracy and confidence. The technique and skill of the radiologist in properly positioning the foot with the MRI beam are critical in demonstrating the sometimes obscure findings of tendon injury around the ankle. Magnetic Resonance Imaging (MRI) is expensive and is not necessary in most cases to diagnose posterior tibial tendon injury. Ultrasound has also been used in some cases to diagnose tendon injury, but this test again is usually not required to make the initial diagnosis.
- MRIDuring the physical examination, the podiatrist will feel and push lightly around the Achilles tendon to see if it is tender or has any irregularities in its surface. Achilles tendonitis may cause the tendon to be thickened in areas, may cause swelling of the area around the tendon, and can even feel like the tendon has a painful bump on it. In addition, the person with Achilles tendonitis will limp while barefoot, but walk more normally with heeled shoes on. X-rays are not helpful in diagnosing Achilles tendonitis but may be taken to rule-out other pathology. MRI scans are only indicated if a partial or complete rupture of the Achilles tendon is suspected by the podiatrist.
- X-Rays
- Computed TomographyThe 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 in 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, CT Scan, and nerve conduction studies have little value in the diagnosis of a neuroma. Additionally, these studies can be very expensive and generally the results do not alter the doctor's treatment plan. 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.
- General SurgeryDuring her second year of residency, she was given an opportunity to be a volunteer surgeon for Mission Peace, a medical mission in Southern Vietnam, which provides Surgical services to correct deformities caused by neurological diseases and Agent Orange. This allowed children and adults the opportunities to have a more functional life and removed the stigma of growing up with a deformity.
- Arthroscopy
- Wound CareNot all ulcers are infected; however, if your podiatrist diagnoses an infection, a treatment program of antibiotics, wound care, and possibly hospitalization will be necessary.
- Ankle Surgery
- Bunion SurgeryCorrective bunion surgery can relieve your pain, correct any related foot deformity, and help you resume your normal activities.
- Joint ReplacementIf the condition progresses to the point of spurring around the joint, surgery may be indicated. Depending upon the degree of degeneration of the joint, surgery may consist of simply removing the bone spurs around the joint, a decompresion osteotomy or may require a total joint replacement or joint fusion ( See surgery of Hallux limitus ). Following surgery, the use of a functional orthotic is useful to improve the joint function.
- Metatarsal SurgeryThere 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.
- BunionsThe 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.
- GangreneIngrown 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. Patients with joint replacements or pace makers are at risk of bacterial spread through the blood stream resulting in the spread of infection to these sites. 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.
- Arthroscopy
- HysterectomyFactors that contribute to the onset of gout are alcohol, red meats, asprin and certain medications for high blood pressure. Gout occurs most frequently in men. Women will not get gout until after menopause unless they have had a hysterectomy. Patients with long standing diabetes who may have kidney damage due to their disease, and patients who have kidney disease from other causes can develop gout. These patients may exhibit atypical forms of gout. In these instances, more than one area may be affected; the tops of both feet, for example, may develop gout.
- Ingrown ToenailsIngrown 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.
- Reconstructive SurgeryWhen foot and ankle deformity develops, custom orthoses and special shoes may be necessary to prevent foot ulcerations and provide stability during ambulation. When ulcerations develop and resist conservative treatment, surgery may be necessary to prevent loss of the foot. Additionally, if there is severe instability, reconstructive surgery of the foot and ankle may be necessary to provide a stable platform for ambulation and to avoid lower leg amputation.
- Hammertoe SurgeryHome 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. See correcting soft corns, removing bone spurs, and hammertoe surgery.
- CornsSoft 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.
- Cyst
- UlcerA diabetic foot ulcer is an open sore or wound that occurs in approximately 15 percent of patients with diabetes and is commonly located on the bottom of the foot. Of those who develop a foot ulcer, 6 percent will be hospitalized due to infection or other ulcer-related complication.
- CallusesThe 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.
- FungusThe 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.
- LesionsAthlete's foot is caused by a fungal infection of the skin on the foot. The majority of these infections are caused by one of three fungal agents called dermatophytes. Athlete's foot is by far the most common fungal infection of the skin. The infection can be either acute or chronic. The recurrent form of the disease is often associated with fungal-infected toenails. The acute form of the infection most often presents with moist, scaling between the toes with occasional small blisters and/or fissures. As the blistering breaks, the infection spreads and can involve large areas of the skin on the foot. The burning and itching that accompany the blisters may cause great discomfort that can be relieved by opening and draining the blisters or applying cool water compresses. The infection can also occur as isolated circular lesions on the bottom or top of the foot. As the skin breaks down from the fungal infection, a secondary bacterial infection can ensue.
- PsoriasisNot 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.

- Sports MedicineExpert Care to Keep You in the Game. There are many injuries such as stress fractures, tendon tears, nerve injury, that are specific to a particular sport.
- Physical TherapyInitially, the patient with Achilles tendonitis will be asked to modify their activities to decrease their running and jumping activities and do alternative physical activities, such as swimming, which don't put as much stress on the Achilles tendon. As the tendon starts to feel better, the podiatrist will allow a gradual return to normal running and jumping activities. If normal return to activities is not possible within a few weeks, then many times the podiatrist may additionally prescribe physical therapy and/or functional foot orthotics to help the tendon heal more rapidly. The foot orthotics generally are used during both the sports activities and walking activities to allow for more normal foot and Achilles tendon function. If the physician is concerned about a partial tear of the tendon the patient may be placed in a below the knee cast. It can take several weeks or even months for the tendon to heal depending upon the severity of the injury to the tendon. It is not uncommon for a patient to return to activities too quickly and re-injure the tendon. Careful monitoring of a return to full activity is important and the patient must have patience during this period of time.

- General PodiatryDr. Timothy Casperson was born in San Antonio, Texas before moving to Conroe where he was raised by Dr. Thomas Casperson and his wife Faith. He is the oldest of two younger sisters who still reside in Texas pursuing their careers. Upon graduating from Conroe High School, he earned a Bachelor's of Science degree in Biomedical Science and graduated with honors from Texas A&M University. He later earned his medical degree from the California School of Podiatric Medicine in San Francisco, California.
- Achilles TendonitisThe most common form of injury to the Achilles tendon is called Achilles tendonitis, which is an inflammatory condition causing pain in the Achilles tendon. Achilles tendonitis generally occurs in people who are active in sports activities. Types of sports that commonly are associated with Achilles tendonitis are basketball, tennis, running, football, soccer, volleyball and other running and jumping sports.
- Ankle Sprain
- Bunions ProblemsOne 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).

- HammertoesSeveral surgical options are available for hammertoe correction. Some corrections can be made with changes to soft tissue. Others need to be made to the bone or joint.
- Heel SpursHeel pain is caused by the excessive pull of a ligament in the arch of the foot called the plantar fascia. Generally the pain can be treated successfully without the need for surgery. However there are instances where non-surgical treatment of heel pain may fail and surgery may be necessary. Very often, the patient with heel pain will demonstrate a heel spur on an x-ray. In the past, many of the surgeries that were performed to relieve heel pain were designed to remove the bone spur. An incision was made on the side of the heel or the bottom of the heel, the spur identified and removed. Unfortunately, the healing time was very protracted and continued pain following the surgery was not uncommon. Now that the cause of heel pain is better-understood ( See heel pain ) the surgery is much more successful and the recovery time greatly diminished.

- Ingrown ToenailsThere 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.
- Foot NeuromaA 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.
- Foot OrthoticsTreatment 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,a night splint, 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 and abnormal pronation of the foot. Surgery to correct heel pain is generally only recommended if orthotic treatment has failed. There are some exceptions to this course of treatment and it is up to you and your doctor 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 eliminate 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.
