What is Charcot Foot?

Charcot foot, also known as Charcot neuroarthropathy or Charcot joint, is a progressive disorder characterized by the breaking and dislocation of the bones, joints, and soft tissues in the foot and ankle. It is a severe diabetic foot or neuropathic complication of the foot. The condition often results in deformity, instability, and an increased risk of ulcers or infections. It primarily affects individuals with peripheral neuropathy, especially those with diabetes, which can lead to a loss of sensation in the affected area.

Causes of Charcot's Foot

The exact cause of Charcot foot remains unclear, but it involves a combination of factors, including:

Neuropathy: Nerve damage, often from diabetes, reduces sensation and the ability to feel pain or temperature changes in the foot.
Trauma: Repeated minor injuries, such as small fractures, can go unnoticed due to neuropathy and may trigger the onset of Charcot’s foot.
Inflammation: The body’s inflammatory response to injury can cause further damage to the bones and joints, exacerbating the condition.

Risk Factors

Risk factors for Charcot neuroarthropathy include:

Diabetes
Peripheral neuropathy
Alcoholism
Spinal cord injuries

Symptoms and Early Warning Signs

Early detection of Charcot neuroarthropathy is crucial for preventing severe complications. Some common symptoms include:

Warmth, redness, and swelling in the foot or ankle
Pain or discomfort (some cases are painless)
Instability or difficulty walking
Deformities, such as a collapsed arch or a rocker-bottom appearance

If you notice any of these symptoms, particularly if you have diabetes or neuropathy, consult a medical professional immediately.

Diagnosis

Charcot foot can look identical to typical foot infections, such as cellulitis. Therefore, your medical practitioner or podiatrist will usually conduct a thorough examination and may refer you for various diagnostic scans to confirm the diagnosis, such as:

X-rays: To identify bone deformities, fractures, or dislocations
MRI scans: To assess soft tissue damage and the extent of the condition
Bone scans: To differentiate Charcot’s foot from other conditions, such as infections or tumours

Treatment Options For Charcot Foot In Singapore

While there is no cure for Charcot foot, early intervention and proper management can prevent severe deformities and preserve foot function. Treatment options in Singapore may include:

Activity modification: Limiting weight-bearing activities to reduce stress on the foot
Immobilization: Using a cast or boot to protect the foot and allow the bones to heal
Custom insoles: Special shoe inserts or braces to provide support and redistribute pressure
Custom walker boot: Special boot to redistribute pressure for cases with severe deformities
Surgery: In severe cases, reconstructive surgery may be necessary to correct deformities and stabilize the foot

Prevention and Management

To minimize the risk of developing Charcot neuroarthropathy or prevent further complications, consider these recommendations:

Monitor your blood sugar levels closely if you have diabetes
Regularly inspect your feet for signs of injury or infection
Wear properly fitting, supportive footwear
Schedule regular check-ups with your podiatrist, particularly if you have neuropathy or other risk factors

Seek Early Medical Attention For Charcot Neuroathropathy

Charcot foot is a severe and potentially life-altering condition that requires prompt attention and treatment. By seeking medical attention early, you can prevent foot deformities associated with this condition. We also highly recommend that individuals with diabetes undergo regular foot screening annually.

The ability to continue working and participating in daily activities while undergoing treatment for Charcot foot depends on the severity of your condition and the treatment you need. Generally, we strongly advise limiting your weight-bearing activities and always using the prescribed devices, cast, or boots to protect your foot. You should only return to normal activities when your medical professionals advise so. Prioritizing your foot’s healing and avoiding activities that could exacerbate the condition or hinder recovery is crucial.
