As many as 2.5 percent of patients with diabetes can develop Charcot foot, and it can recur in as many as five percent of cases.
Fortunately, your doctor can help you in treating Charcot foot, largely reversing the damage it causes. Depending upon the severity of your case, you could receive medical or surgical therapy. Any treatment option you receive will have similar goals: take weight off the injured foot, address bone disease, and prevent future foot fractures.
Charcot Foot Diagnosis
Imaging scans can help your doctor determine what treatment type you need. X-rays offer detailed pictures of dense structures, such as bones. MRI and ultrasound provide good imaging of foot and ankle soft tissues, potentially identifying any bone infections. Bone scans are nuclear tests that can also identify bone infections. A specific test — an indium scan — tags your white blood cells and follows them to the infection site.
Treating Charcot Foot
Whether your doctor recommends surgical or non-surgical treatment, you will get the best long-term results if you closely follow your physician’s instructions. Most specifically, wait until he or she tells you it’s safe to put weight on your foot again.
Also, be sure to check your feet daily for any problems, including scrapes or lingering sores. If any exist, immediately contact your doctor. The sooner you get treatment, the more likely you are to have a good outcome.
Non-surgical treatment: Offloading — keeping your weight off your affected foot — is the most important part of treating Charcot foot without surgery. For anywhere from 8-to-12 weeks, you’ll wear a protective walking boot or cast. The protective footwear should stay in place until any redness, swelling, or heat disappears. The Charcot Restraint Orthotic Walker (CROW) is a commonly used device.
The second step is prescription orthotic shoes. These shoes must fit appropriately, providing enough room for your toes and enough cushioning for the heel, arch, and ball of your foot. The right shoes won’t have any pressure points, reducing the risk of injury or ulcers.
You’ll also need to change your activities to avoid repetitive trauma to both feet.
Surgical treatment: Surgery is recommended for individuals with severe ankle and foot deformities that could make using a brace or other orthotics difficult. These patients are also at a higher risk for developing foot ulcers.
Surgery could involve re-aligning the bones of your foot or removing some that could cause ulcers. According to recent research, most patients with diabetes are able to resume normal walking after surgery.
Because infection risk is high post-surgery, you’ll be instructed not to put your full weight on your foot until your doctor gives you the green light. You’ll also need to commit to wearing protective footwear for life.
Remember, it is possible for Charcot foot to return, so stay vigilant with your foot hygiene.
