Charcot neuroarthropathy is a severe and potentially limb-threatening complication of diabetes, characterised by progressive bone and joint disintegration in the foot. It is most commonly seen in patients with peripheral neuropathy, which masks the pain that would normally accompany such damage.
Early signs include swelling, warmth, and redness in the foot, often mistaken for infection. Left untreated, the foot can collapse structurally, leading to a ‘rocker-bottom’ deformity. Early diagnosis is critical, as timely immobilisation can halt the destructive process.
In South Africa, Charcot foot is underdiagnosed, partly due to limited awareness and access to imaging modalities like MRI, which is often needed for confirmation. Podiatrists should maintain a high index of suspicion in patients with known neuropathy and unilateral foot changes.
While surgical intervention may be necessary in advanced cases, early-stage management with total contact casting or removable walkers is the cornerstone. Education of patients and clinicians alike is key to improving outcomes.
Charcot foot requires swift diagnosis and management to prevent severe deformity. South African podiatrists can lead in early recognition and referral for limb-saving intervention.
