Vascular Testing in Podiatry
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.
What is Morton's Neuroma?
Morton’s neuroma, (also referred to as Morton’s metatarsalgia, Morton’s neuralgia, plantar neuroma or intermetatarsal neuroma) is a condition that is caused when the tissue around one of the nerves between your toes begins to thicken. This thickening can result in pain in the ball of the foot. Fortunately, the condition itself is not cancerous.
Morton’s neuroma affects women more often than men with a ratio of 4:1. It tends to target women between the age of 50 and 60, but it can occur in people of all ages. There are some risk factors that may put you at a slightly higher risk of developing the condition. People who often wear narrow or high-heeled shoes are often found to be linked to Morton’s neuroma. Additionally, activities such as running or jogging can put an enormous amount of pressure on the ligament and cause the nerve to thicken.
There usually aren’t any outward symptoms of this condition. A person who has Morton’s neuroma may feel as if they are standing on a pebble in their shoe. They may also feel a tingling or numbness in the toes as well as a burning pain in the ball of their foot that may radiate to their toes.
In order to properly diagnose you, the doctor will press on your foot to feel for a mass or tender spot. He may also do a series of tests such as x-rays, an ultrasound, or an MRI. X-rays are usually done to rule out any other causes for your foot pain such as a stress fracture. Ultrasounds are used to reveal soft tissue abnormalities that may exist, such as neuromas. Your podiatrist may want to use an MRI in order to visualize your soft tissues.
There are three main options for treatment of Morton’s neuroma: Injections, decompression surgery, and removal of the nerve. Injections of steroids into the painful area have been proven to help those with Morton’s neuroma. Decompression surgery has been shown to relieve pressure on the affected nerve by cutting nearby structures such as the ligaments in the foot. Another treatment option would be to surgically remove the growth to provide pain relief.
If you suspect that you have Morton’s neuroma you should make an appointment with your podiatrist right away. You shouldn’t ignore any foot pain that lasts longer than a few days, especially if the pain does not improve.
Treating Tarsal Tunnel Syndrome
Tarsal tunnel syndrome is a condition in which the tibial nerve, located in the tarsal tunnel in the foot, is compressed. The tibial nerve can become compressed from injury, such as an ankle sprain, flat feet, and lesions. Arthritis, diabetes, and varicose veins can also cause swelling and thus result in nerve compression.
Symptoms of tarsal tunnel syndrome include several different sensations in the sole of the foot, inside the ankle, and around the tibial nerve. These sensations include shooting pains, numbness or reduced sensation, pins and needles, burning, and tingling. Symptoms tend to worsen with greater activity to the area. In rare and severe occasions, this can change the muscles in the foot.
If you suspect you have tarsal tunnel syndrome, you should consult with your podiatrist. He or she will examine your medical history to see if you have a history of diabetes, arthritis, or flat feet. They will also check to see if you have suffered an injury to the area recently. An electrical test will be conducted to check if the nerve has been damaged. A simpler Tinel’s Test might also be used. This includes simply tapping the nerve to create a sensation. An MRI scan of the area may also be used.
Treatments vary greatly for tarsal tunnel syndrome. Treatments include both nonsurgical and surgical options depending upon the severity of the condition. Nonsurgical options include anti-inflammatory medication and steroid injections to the area. Orthotics, such as a splint or brace that immobilizes the foot, is another noninvasive option. For those with flat feet, custom shoes can be made to offer better foot support. Surgical options include a tunnel tarsal release, in which an incision is made behind the ankle down to the arch of the foot. This releases the ligament and relieves pressure off the nerve. Some doctors use a more minimally invasive surgery, where smaller incisions are made in the ankle and the ligament is stretched out.
If you are suffering from painful sensations in your foot, see a podiatrist who can determine if you are experiencing tarsal tunnel syndrome. Tarsal tunnel syndrome that is left unchecked can cause permanent nerve damage to the foot.
The ankle joint is the point at which the bones of the leg and foot join. This joint is crucial because it is responsible for the foot’s mobility. Ankle pain is typically the result of inflammation from an injury to bones, joint space, cartilage, ligaments, tendons, or muscles in the area. Commonly associated symptoms with ankle pain are bruising, redness, numbness, stiffness, weakness, and tingling.
The most common causes of ankle pain are sprains and injuries. Ankle sprains are one of the most common musculoskeletal injuries. Sprains occur when the ligaments of the ankle become partially or completely torn due to sudden stretching. Sprains can occur on either the inner or outer sides of the ankle joint. Usually, these injuries occur when the ankle is twisted in an activity by stepping off an uneven surface. More specific causes include rheumatoid arthritis, gout, osteoarthritis, and Achilles tendonitis.
If you are experiencing ankle pain, you should consult with your podiatrist to choose the best method of care. Your doctor will conduct an examination of your ankle to determine the underlying cause of the pain.
Flatfoot is a foot disorder that is not as straightforward as many people believe. Various types of flatfoot exist, each with their own varying deformities and symptoms. The partial or total collapse of the arch, however, is a characteristic common to all types of flatfoot. Other signs of flatfoot include:
- “Toe drift,” or the pointing outward of the toes and the front part of the foot
- The tilting outward of the heel and the tilting inward of the ankle
- The lifting of the heel off the ground earlier when walking due to a tight Achilles tendon
One of the most common types of flatfoot is flexible flatfoot. This variation usually starts in childhood and progresses as one ages into adulthood. Flexible flatfoot presents as a foot that is flat when standing, or weight-bearing. When not standing, the arch returns. Symptoms of flexible flatfoot include:
- Pain located in the heel, arch, ankle, or along the outside of the foot
- Overpronation, or an ankle that rolls in
- Shin splint, or pain along the shin bone
- General foot aches or fatigue
- Pain located in the lower back, hip, or knee
Your podiatrist will most likely diagnose flatfoot by examining your feet when you stand and sit. X-rays may be taken to define the severity and help determine the treatment option best for your condition. Nonsurgical treatments can include activity modification, weight loss, orthotics, immobilization, medications, physical therapy, shoe modifications, and ankle foot orthoses (AFO) devices. If nonsurgical methods prove ineffective, surgery may be considered. Multiple surgical procedures can correct flatfoot; and depending on your specific condition, one may be selected alone or combined with other techniques to ensure optimal results.
