Charcot Foot And Ankle

What is Charcot foot?

Charcot foot, also known as Charcot neuroarthropathy, is a progressive condition in which the bones and joints of the foot become weakened and damaged. Because many patients with Charcot foot have decreased sensation due to neuropathy, they may continue walking on an injured foot without realizing the extent of the damage.

Over time, the bones can fracture and the joints can dislocate, resulting in significant deformity and collapse of the arch of the foot. Left untreated, Charcot foot can lead to chronic wounds, infection, and even amputation.

What causes Charcot foot?

Charcot foot most commonly develops in patients with peripheral neuropathy, particularly those with diabetes. Other potential causes include:

• Diabetes-related neuropathy
• Previous foot or ankle trauma
• Spinal cord injuries
• Alcohol-related neuropathy
• Peripheral nerve disorders
• Certain neurologic conditions

Because patients with neuropathy often have reduced sensation in their feet, even minor injuries can progress to severe joint and bone damage.

What are the symptoms of Charcot foot?

Early diagnosis is critical, as symptoms may initially resemble those of an infection or sprain. Common symptoms include:

• Swelling of the foot or ankle
• Warmth compared to the opposite foot
• Redness
• Pain or discomfort, although some patients experience little pain
• Changes in foot shape or arch height
• Instability when walking
• Difficulty fitting into shoes

As the condition progresses, patients may develop a rocker-bottom deformity, in which the arch collapses and the bottom of the foot becomes rounded.

How is Charcot foot diagnosed?

Your physician will perform a thorough examination and may order imaging studies to evaluate the bones and joints of your foot and ankle.

Diagnostic tests may include:

• X-rays
• MRI scans
• CT scans
• Bone scans
• Laboratory studies to rule out infection

Early diagnosis and treatment are essential to prevent permanent deformity and other serious complications.

How is Charcot foot treated?

Treatment focuses on protecting the foot, preventing further damage, and preserving long-term function. Depending on the severity of your condition, your physician may recommend:

• Immobilization in a cast or walking boot
• Strict limitation of weight-bearing activities
• Custom orthotics or bracing
• Diabetic footwear
• Regular monitoring with imaging studies
• Physical therapy and rehabilitation
• Management of underlying diabetes and neuropathy

For patients with severe deformity, instability, or chronic wounds, surgery may be necessary to reconstruct the foot, stabilize the joints, or reduce pressure points that can lead to ulceration.

Early treatment can significantly reduce the risk of complications and help preserve mobility and independence. If you have diabetes, neuropathy, or unexplained swelling and warmth in your foot, contact Metropolitan Foot and Ankle Specialists as soon as possible to schedule an evaluation.
