Abstract:
Few studies have evaluated the long-term clinical outcomes of Charcot foot. The present study evaluated the long-term effects of Charcot foot in a population treated with early weightbearing in a removable Charcot restraint orthotic walker. A retrospective study of 62 consecutive patients (74 feet) treated for Charcot foot from January 2003 to March 2014 was conducted. Of the 74 affected feet, 48 (64.9%) had developed an ulcer. The total amputation rate was 25.7% (19 feet), and 11 feet (14.9%) underwent major amputations. The mortality rate was 19.4% (12 patients). Low Short-Form 36-item scores for all subcomponents were found. The major amputation rate was significantly greater for hindfoot than for midfoot manifestations. Charcot foot results in a high risk of chronic ulceration. The hindfoot Charcot manifestation was associated with a high rate of major amputations. Early weightbearing in a Charcot restraint orthotic walker as treatment of Charcot foot was not supported by the results from the present study.
