Charcot Neuroarthropathy

What is Charcot Neuroarthropathy

Charcot Neuroarthropathy is a condition causing weakening of the bones in the foot and ankle. This condition occurs in people who have neuropathy/nerve damage in their feet. This can lead to fractures, destruction of bone and collapse of the foot and ankle.

Causes

Charcot develops as a result of a combination of 3 process. The 1st process is secondary to neuropathy. Because neuropathy causes diminished sensation and ability to feel pain, there is increased stress and pressure on the foot as a result. The 2nd process is an increase blood flow to the foot and ankle resulting in demineralization of the bone. The last process is the increase in bone breakdown/reabsorption .

Symptoms

Increased temperature to the foot and ankle (affected foot feels warmer)
Redness
Swelling
Pain or soreness
Deformity of the foot or ankle

Diagnosis

Early diagnosis of charcot is extremely important for successful treatment. Clinical examination is important in determining if charcot is occurring and at which stage the charcot deformity is currently at.

Stages of Charcot

Acute- increased temperature, redness, swelling, pain. X-rays will show minimal to no signs of bone/joint breakdown
Subacute- temperature, redness and swelling begin to normalizes. X-rays will show bone breakdown
Chronic/consolidation- temperature, redness and swelling normal. X-rays show consolidation of the bones/joints affected likely in an abnormal/deformed position

Treatment

Non-surgical

Immobilization
Orthotics
Bracing
Custom shoes

Surgical

Surgery is considered in cases that are more severe. These cases are either unbraceable or a wound is present.
