Background
- 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.
Epidemeology
It has been reported that Charcot affects between 0.1% to 0.9% of people with diabetes. An estimated 63% of patients with Charcot neuropathic osteoarthropathy will develop a foot ulceration. McEwen et al. found a significant association between elevated body mass index and Charcot arthropathy.
