In foot care, vascular testing may be required in the diagnosing and treatment of certain podiatric conditions. Vascular testing is particularly relevant for patients with high-risk diabetes, poor circulation, peripheral artery disease (PAD), and chronic venous insufficiency (CVI). Procedures typically involve the examination of blood vessels throughout the body for blockages or buildup.

Vascular testing is very important for the diagnosis of various conditions, including peripheral artery disease and chronic venous insufficiency, as these conditions can greatly affect one’s quality of life and cause pain in the lower limbs. Circulatory problems in the feet and ankles can reflect issues throughout the body, making testing of the blood vessels pertinent.

Testing methods vary between practitioners and can be specific to certain foot and ankle problems. Modern technology has brought about the ability to perform vascular testing using non-invasive methods, such as the cuff-based PADnet testing device. This device records the Ankle-Brachial Index (ABI)/Toe-Brachial Index (TBI) values and Pulse Volume Recording (PVR) waveforms. Contact your podiatrist to determine what vascular testing is available for your needs.

Orthotics are shoe inserts that are meant to correct an irregular walking gait or provide cushioning to the feet.  Orthotics come in a variety of different models and sizes, including over-the-counter and customizable variants. Customizable orthotics can be shaped and contoured to fit inside a specific shoe and are typically prescribed through a podiatrist who specializes in customized footwear and orthotics design and management.

Orthotics are beneficial because they can help prevent injuries from occurring and provide cushioning to keep pain levels down to a minimum. They also allow for the correct positioning of the feet. Orthotics can act as shock absorbers to help remove pressure from the foot and ankle. Therefore, orthotics can make bodily movements, such as walking and running, become more comfortable as well as help prevent the development of certain foot conditions.

Orthotics alleviate pain and make the foot more comfortable by slightly altering the angle at which the foot strikes the ground surface, therefore controlling the movement of the foot and ankle. Orthotics come in different variants and can be made of various materials. To determine what type of orthotic is most suited to your feet and your needs, it is best to consult your podiatrist. He or she will be able to recommend a type of orthotic that can help improve your foot function or prescribe a custom orthotic to best fit your feet.  

Blisters are small pockets of fluid that occur on the top layers of the skin for several reasons. Friction, burns, and diseases are all known causes of blisters.  Smaller blisters are known as vesicles, while larger blisters are referred to as bulla. The fluid inside the bubble can be blood, pus, or serum; which is a clear liquid that protects the skin. In most cases, blisters are not a major health issue, but they can be an indicator of a more serious condition.  

Causes of blisters vary. Blisters are commonly caused by wearing poorly fitted shoes that rub against the foot. However, there are many other causes besides from friction; including burns, sunburn, insect bites, frostbite, poison ivy/oak, chemical exposure, impetigo, eczema, viral infections, and more.

Most blisters heal by themselves and do not require immediate medical care. If you have a blister, do not pop it since this may cause infection; it is advised to put a bandage over the blister to protect it. If the blister is large, causes pain, or if you have a fever, it is recommended that you see a doctor who can provide proper care. Blisters are easy to diagnose, and if considered prudent by the doctor, can easily be drained of fluid with a sterile needle as well.

To prevent blisters on the feet, wear shoes that fit properly and don’t cause rubbing. Socks can help prevent friction and it is recommended that you wear them if you are wearing shoes. Hand blisters can be avoided by wearing gloves during activities that cause friction against the hand. If you have a blister that pops, do not remove the dead skin, wash the area, apply antibiotic ointment, and cover with a bandage. It is okay in most cases to not seek immediate medical care for a blister if it was just caused by friction. However, if the blister causes pain or does not go away, it is suggested that you see a doctor for a diagnosis.

Limb salvage is a procedure that involves saving a lower extremity from amputation. In podiatry, limb amputation often occurs as a result of diabetes, peripheral vascular disease, neuropathy, cancer, and severe crush injury. The fundamental goal of limb salvage is to restore and maintain stability and movement of the affected lower extremity.

The procedure typically involves removing the diseased tissue and a small portion of the surrounding healthy tissue, as well as the removal of any affected bone if necessary. If the bone is removed, it is then replaced with prostheses, synthetic metal rods or plates, or grafts from either the patient’s body or a donor. Limb salvage is typically the preferred choice of procedure over amputation, as the procedure preserves both the patient’s appearance and allows for the greatest possible degree of function in the affected limb.

Upon diagnosis and determining that limb salvage is the appropriate treatment, the podiatrist may enlist the help of a physical and/or occupational therapist to prepare the patient for surgery by introducing various muscle-strengthening, walking, and range of motion exercises. Such exercises may be continued as rehabilitation post-procedure.
