Charcot Foot: Difference between revisions

Revision as of 11:08, 1 August 2025

Charcot neuropathic osteoarthropathy (Charcot joint) is a destructive joint disorder initiated by trauma to a neuropathic extremity. It can lead to dislocations and fractures of the foot. Diabetes, neuropathy, trauma, and metabolic abnormalities of the bone result in an acute localized inflammatory condition. The inflammatory response can permanently disrupt the bony architecture of the foot resulting in abnormal plantar pressures that are at risk for ulceration, osteomyelitis, and amputation.

Charcot joint develops in about 0.1% to 0.9% of people with diabetes.
Majority of these patients will develop a foot ulceration.
There is a significant association between elevated body mass index and Charcot arthropathy.
