If you have diabetes, you probably already know that you need to take extra care of your feet. But sometimes, you may not even realize that your feet are red, swollen, or feel warm to the touch. If you ignore it, thinking, "This is just a small thing," it could be the beginning of a serious condition called Charcot Foot, or Charcot Arthropathy, which damages the bones, joints, and soft tissues of your feet. Today, let's learn more about this silent condition.
What exactly is Charcot Foot?
Simply put, Charcot Foot is a condition in which the nerves in the feet are damaged and the bones, joints, and tissues in the feet are damaged, resulting in loss of sensation. You may not notice much difference at first. But over time, it can lead to non-healing sores on the legs and completely change the shape of the feet. But don't panic. If you are aware of this and recognize the early signs, your doctor can treat it before it causes any serious damage.
Why does this happen? Causes and risk factors
Charcot Foot is a condition that occurs in people who have lost sensation due to
nerve damage, mainly in the feet and ankles. The main cause of this nerve damage is uncontrolled diabetes. However, this condition can also occur for other reasons besides diabetes.
| Causes of nerve damage | Triggers that aggravate Charcot Foot |
|---|
| Diabetes (Diabetes Mellitus) | Not getting prompt treatment for a sprained leg or broken bone |
| Alcohol or drug abuse | Having a non-healing sore on the soles of the feet |
| Spinal diseases or injuries | The presence of an infection |
| Parkinson's disease | Delayed healing after leg surgery |
| Infections such as HIV or syphilis | - |
Think about it this way. Because your foot has little sensation, even if your foot is slightly sprained or a stone gets stuck in your shoe, you don't feel it. So you keep walking on that foot without any concern. What happens is that the injured area gets more and more damaged. Gradually, the bones in your foot lose the calcium needed for strength, and the bones start to weaken. This is how Charcot Foot begins.
What are the serious complications of this?
When bones become weak, they can break easily and shift out of place. When this happens, things like this can happen:
- Changes in the shape of your feet: The arch in your foot may be lost, and the middle of your foot may flatten out. Sometimes this can be so severe that the bones in the middle of your foot drop down, making your bottom look like the rocking part of a chair. Doctors call this a "rocker bottom."
- Toe twitching: The toes of both feet may rub against each other and twitch.
- Ankle instability: The ankle area can become twisted and unstable, making it impossible to stand properly.
- Non-healing wounds : Sharp bone fragments can become lodged in the skin , causing open sores that are difficult to heal. Because people with diabetes have poor blood supply , these wounds can become infected and take longer to heal.
- Amputation : If the infection cannot be controlled, the leg may need to be surgically removed (amputation). This is the most serious complication .
Most importantly: If you have diabetes , don't ignore even the slightest change in your feet. See your doctor right away.
How to recognize the first symptoms?
As Charcot Foot begins, you may notice these symptoms on your foot:
- Getting red
- Feeling warm when touched
- Swelling
Because these symptoms can also be seen in other medical conditions (e.g., an infection), it can be difficult to tell if it is Charcot Foot at first. It may not even be detected by X-rays at first. Therefore, if you have a foot problem, especially a diabetic foot problem, it is important to see a doctor who has experience with it.
How is it treated?
Treatment for Charcot Foot can take several months. The main goal is
to off-load and relieve pressure on the affected foot.
Resting and protecting the leg
Your doctor will first put a cast on your leg. This will protect your leg and stop it from moving around. As the swelling goes down, you will need to change the cast several times over a period of 2-3 months. During this time, you will need to use crutches, a wheelchair, or a knee walker to walk.
Preventing new problems from occurring
After the cast is removed, you will need to wear special shoes (prescription shoes) that fit your feet exactly, recommended by a doctor. These shoes identify areas of excessive pressure on your feet, reduce pressure on those areas, and prevent new injuries from forming. You may also need to wear a brace.
Bone preparation through surgery
Your doctor will only recommend surgery if the damage to your leg bones is causing instability, or if special shoes don't help. During surgery, the surgeon may realign or fuse the bones that have moved out of place. They may also remove any sharp bone fragments that may be poking through the skin, preventing further injury.
