What Are Ankle/Foot Orthosis?
Ankle-foot orthosis are braces worn at the ankle that encompass some or all of the foot. Diseases that affect the musculature or weaken the affected area require orthosis to strengthen the muscles or rehabilitate them and other joints of the foot and ankle. Tight muscles that need to be lengthened and loosened also benefit from orthosis.
When we think of diseases that affect the musculature we think of the big boys: muscular dystrophy, cerebral palsy, polio and multiple sclerosis. We rarely think that arthritis and stroke can affect the musculature, but these are both conditions that can negatively affect the muscles in your foot and ankle.
However, the good news is that whatever trauma there is that affects those muscles, there is a way to correct it. The orthosis helps to control range of motion, provide support by stabilizing walking, correct deformities, and manage pain loads. A podiatrist would be consulted for those who have experienced direct trauma to the foot or ankle, have an arthritic condition that is affecting their joints, or has developed another kind of muscular disease.
Before the advent of modern orthosis devices, it wasn’t uncommon to see polio victims wearing metal braces from mid thigh to the bottom of the foot, or children wearing metal braces around their ankle and foot. However, both designs and materials have improved dramatically, allowing for new levels of comfort, functionality, and appearance. Many orthosis are now made from plastics in the shape of an L and designed to fit inside a corrective shoe. These can be rigid, buckling at the calf and extending the length of the foot to support the ankle. This same design except with a hinged ankle provides support while walking by normalizing the gait. In the past, boots lined with leather and fiberboard provided the rigidity needed for correction and support. Now corrective shoes are available with built up soles to correct the gait or manage pain by sharing it with another area when the foot spreads during walking.
The podiatrist would prescribe this orthosis in the rigid L shape because the foot moves on a hinge. If the hinge isn't functioning as intended due to an injury or malformation, the muscles tighten up, thus making it difficult to flex the foot. When we walk, the foot flexes and muscles stretch. This brace or orthosis would support the ankle and musculature during flexion of the foot, in much the same way a knee brace works. Corrective shoes are for people whose feet hit the ground backward, causing tight muscles and arch problems. Wedges and rocker bars on the heels correct the step to heel first and rock onto the ball of the foot, resulting in relaxed musculature and strengthened ankles.
Appearance also counts when we consider a particular support device, especially if the item is intended for regular, daily wear. The L shaped orthosis is contoured to the calf and flesh-colored, fitting into a sneaker or dress shoe. At present, corrective shoes are more attractive than past models, enabling patients wear such devices with greater comfort and confidence.
About Plantar Warts
The term plantar means relating to the foot, which is why plantar warts are only found on the feet. Plantar warts are caused by the human papillomavirus (HPV) getting into open wounds on the feet. These warts are recognizable by a hard bump on the foot. They are mostly found heels or on the balls of the feet. Plantar warts are basically harmless, and may be ignored unless they cause pain or embarrassment.
If you have a plantar wart you may notice some pain when standing, or just some tenderness on the sole of your foot. You will be able to see a fleshy wart, unless it has grown into the foot behind a callus. Since plantar warts are not cancerous and not dangerous, a podiatrist only needs to be seen if there is excess pain, the warts come back often or persist for some time, or if it affects walking. It is extremely important that people suffering from compromised immune systems or diabetes seek out a physician’s care immediately upon finding a plantar wart on their foot.
Doctors can usually easily diagnose plantar warts. The doctor will scrape off a tiny bit of the rough skin to make tiny blood clots visible that make up the inside of these warts. If the doctor is unsure of a diagnosis they may do a biopsy to be certain. Though plantar warts don't often call for treatment, there are many options for combating them if need be. They can be frozen using liquid nitrogen, removed using an electric tool or burned using laser treatment. For a less invasive treatment a topical cream can be used which is available only through a prescription. Over the counter wart medications may help, given enough time and patience.
If you prefer to use home remedies an apple cider vinegar soak is believed to help remove the wart. This treatment takes time. Soak your infected foot in the vinegar for 20 minutes before using a pumice stone to remove any loose skin from the wart. Keep the wart covered for protection in between daily treatments.
The best way to avoid contracting plantar warts is to avoid walking barefoot in public areas. This includes wearing shoes in public showers also. It is also important to avoid direct contact with warts, as they can be contagious. This means not touching your own warts, as well as those on others.
Stress Fractures to the Foot and Ankle
Dealing with Stress Fractures of the Foot and Ankle
Stress fractures in the foot and ankle happen when muscles become weak due to too much or too little use. Stress fractures cause the muscles to stop cushioning the foot and ankles from the impact of hitting the ground. Since there is nothing to protect the bones of the foot, they absorb the full impact of each step you take. This additional stress causes little cracks, or stress fractures, to form in the bones that are being pressured.
Stress fractures are common in highly active people, especially athletes. Basketball, tennis or and gymnastics are activities where stress fractures occur more frequently. However, anyone can receive a stress fracture. Normally sedentary individuals who suddenly begin an intensive high impact work out may incur a stress fracture. This is because their muscles are not resistant enough to handle and cushion the intensity of the activity. Osteoporosis patients may also suffer stress fractures because the disease weakens the victim’s bones, making it easier for them to wear and tear.
Pain from stress fractures occurs in the site area of the fracture. It may be either constant or intermittent, causing sharp or dull pain accompanied by swelling and/or tenderness. Engagement in any kind of high impact activity will only exacerbate the pain. In fact, it can even cause a full fracture, especially when the area is not fully healed. Full fractures are much more serious, and can prevent you from using your foot at all.
Treatment varies depending on the patient and the degree of his or her injury. The most important treatment is to rest the injured foot. Some fractures may heal quicker with brief rest, while others need a longer rest period and utilizing crutches. In some cases surgery is required to install support pins around the fracture to aid healing.
To prevent stress fractures, be sure to get plenty of Calcium and Vitamin-D in your diet. This helps keep your bones strong and fortifies their resistance. If you begin a new regimen that involves high impact activity, set incremental goals on a weekly basis so you can build up the proper muscular strength. For example, if you wish to walk every day, you could ride a bike on some of those days to take stress off your feet. Also, make sure to wear supportive shoes that provide adequate protection.
If you experience any symptoms of stress fractures, you should stop exercising and rest. If these symptoms do not go relieve themselves, consult with an orthopedic specialist. Taking these measures can help prevent stress fractures to your foot and ankle, and allow you to continue the activities you enjoy.
