Charcot foot disease: A new approach

Charcot neuropathic osteoarthropathy (CNO) is a condition that develops in the presence of neuropathy, most commonly diabetes-related neuropathy. Owing to the neuropathy, microtrauma to the bones occur without the individual feeling them. With continued walking, bone inflammation, resorption, microfractures and structural changes occur in the bones, which result in irreversible deformities. Diagnosing this condition is often difficult and requires advanced imaging techniques, such as scintigraphy or magnetic resonance imaging, as X-ray changes may not be specific. Treatment of CNO includes immobilization, offloading, recalcification (supplementation of vitamin D and calcium) and in the most advanced cases, surgical treatment. This narrative review aims to synthesize the recent research and clinical implications relating to Charcot foot to help healthcare professionals to stay up-to-date in this relevant topic.
