Some symptoms of Charcot foot disease are redness, warmness to the touch and swelling, according to Cleveland Clinic. Symptoms may be different depending on how advanced the disease is, explains the American Orthopaedic Foot and Ankle Society.
When fractures and dislocations occur in Charcot foot disease, deformities of the foot and ankle can result, states the American Orthopaedic Foot and Ankle Society. One such deformity is collapse of the midfoot arch. The ankle and hindfoot may also become unstable. The disease usually progresses through three phases.
In the development-fragmentation phase, the redness, swelling and warmth are usually significant, states the American Orthopaedic Foot and Ankle Society. Bony fragmentation and joint dislocation may occur a few weeks into the disease. In the coalescence phase, the redness, swelling and warmth decrease as the bones begin to heal. The reconstruction-consolidation phase demonstrates complete resolution of redness, swelling and warmth. Bones frequently end up healed with nonunion and residual deformity.
The resulting deformities can lead to ulcers due to shoe pressure against bone, explains the American Orthopaedic Foot and Ankle Society. These ulcers may lead to infections, and if infections become severe, they can threaten the limb. Preventative foot care and protective shoes are beneficial, and patients with Charcot foot disease should also have regular appointments with a foot and ankle specialist, states Cleveland Clinic.
