Charcot Foot, also known as Neuropathic Arthropathy, is a serious and progressive condition that affects the bones, joints, and soft tissues of the foot. It is often associated with diabetic neuropathy, where nerve damage leads to a loss of sensation in the feet, making it more difficult to detect injury or abnormal pressure. 

This can lead to joint instability, deformity, and even fractures. At Palms Physiotherapy & Allied Health, we specialise in diagnosing and managing Charcot foot to help restore mobility and prevent further damage.

Charcot Foot (Neuropathic Arthropathy): Causes, Symptoms, and Treatment

What Is Charcot Foot?

Charcot Foot is a condition that causes the bones, joints, and soft tissues of the foot to deteriorate due to nerve damage. When the nerves in the feet become damaged—typically from diabetes or other conditions that cause neuropathy—patients may not feel pain or discomfort from injuries. This lack of pain perception allows small injuries to worsen over time, leading to significant joint damage, fractures, and deformity in the foot.

Causes of Charcot Foot

Diabetic Neuropathy

• Diabetes: Charcot Foot is most commonly associated with diabetes, particularly when blood sugar levels are poorly controlled. Diabetic neuropathy (nerve damage) results in a loss of sensation in the feet, making it difficult to detect injuries or changes in foot structure.

• Peripheral Neuropathy: In diabetic neuropathy, the nerves responsible for feeling pain, temperature, and pressure in the feet are affected. Without the ability to feel pain, stress or injuries to the foot can go unnoticed, leading to further damage.

Other Neurological Conditions

• Alcoholic Neuropathy: Chronic alcohol consumption can lead to neuropathy, which increases the risk of developing Charcot Foot.

• Other Causes of Neuropathy: Conditions such as spinal cord injuries, syphilis, leprosy, and hereditary neuropathy can also contribute to the development of Charcot Foot.

Trauma or Injury

• Repetitive Stress: Chronic injuries or stress to the foot, even if unnoticed due to lack of pain sensation, can lead to deformities associated with Charcot Foot.

• Fractures: Even minor fractures that go undiagnosed due to lack of pain sensation can lead to significant joint deterioration over time.

Symptoms of Charcot Foot

The symptoms of Charcot Foot can vary depending on the stage of the condition, but common signs include:

• Swelling: Swelling and inflammation around the foot and ankle are typical symptoms, especially during the early stages of the condition.

• Redness and Warmth: The affected area may appear red and feel warm to the touch, due to inflammation and increased blood flow.

• Deformity: As the disease progresses, structural changes in the foot can occur, including collapse of the arch, the appearance of a rocker-bottom foot, or other deformities.

• Loss of Foot Arch: The arch of the foot may flatten or collapse, altering the way the foot functions and how weight is distributed during walking.

• Instability: The foot can become unstable due to damage to the joints and ligaments, making it difficult to walk or bear weight.

• Fractures and Bone Deformities: Broken bones and joint dislocations can occur without the patient being aware of the injury due to neuropathy.

• Inability to Bear Weight: In severe cases, the affected foot may become so deformed or unstable that it becomes difficult to walk or bear weight.

Diagnosing Charcot Foot

Clinical Examination

A healthcare provider will perform a thorough physical examination to assess the structure and function of the foot. They will look for signs of swelling, deformity, and other characteristic symptoms of Charcot Foot.

Imaging Studies

• X-rays: X-rays are the most common imaging tool used to identify fractures, joint deformities, and bone destruction in the foot.

• MRI or CT Scans: MRI or CT scans may be used for detailed images of the bones, joints, and soft tissues to assess the extent of damage, particularly when X-rays don’t provide enough information.

• Bone Scans: Bone scans may be used to detect active inflammation and help differentiate Charcot Foot from other conditions that might cause similar symptoms.
