This Classifications in Brief article reviews the Eichenholtz staging system for Charcot arthropathy — a progressive, noninfectious joint destruction most commonly caused by diabetic neuropathy. It traces the system from Eichenholtz's 1966 monograph (68 patients), explains each stage's clinical and radiographic criteria, and maps stages to treatment decisions. The Brodsky anatomic classification and Shibata's prodromal Stage 0 modification are also reviewed.
The foot presenting with unilateral swelling, warmth, and erythema in a diabetic patient with peripheral neuropathy may have normal radiographs — and still have active Charcot arthropathy.
This is Stage 0, the prodromal phase Shibata added in 1990. If you wait for radiographic fragmentation (Stage I) before immobilizing, the window to prevent skeletal destruction has already closed. When you see a warm, swollen neuropathic foot with normal X-rays, the answer is total contact casting and protected weightbearing. Not reassurance.
For Stage III disease, the key branch point is plantigrade vs. Non-plantigrade foot. A plantigrade, stable, ulcer-free foot gets custom shoes with a rigid shank and rocker bottom sole. A non-plantigrade foot or one with ulceration requires surgical correction, exostectomy, or fusion with internal fixation.
MRI is the most sensitive modality for early disease. Order it when clinical suspicion is high and plain films are negative.
