Background and Aims: The incidence of diabetic Charcot neuroarthropathy has increased. The purpose here was to study the current diagnostics and treatment of the Charcot foot. Materials and Methods: During a time period from 1994 to 2000, a total of 36 feet were diagnosed as cases of diabetic Charcot neuroarthropathies. A retrospective analysis of patient records and radiographs was undertaken. A review of the recent literature is presented. Results: 29 cases were diagnosed in the dissolution stage, 2 in coalascence, and 5 in the resolution stage. The diagnostic delay averaged 29 weeks. Treatment with cast immobilisation ranged from 4 to 37 weeks (mean 11 weeks). A total of 14 surgical procedures were carried out on 10 patients: six exostectomies, four midfoot arthrodeses, one triple arthrodesis, one tibiocalcaneal arthrodesis and two below-knee amputations. radiological fusion was achieved in two thirds of the attempted arthrodeses. Conclusions: A physician should always consider the Charcot neuroarthropathy when a diabetic patient has an inflamed foot. In the absence of fever, elevated CRP or ESR, infection is a highly unlikely diagnosis, and a Charcot process should primarily be considered. The initial treatment of an inflamed Charcot foot consists in sufficiently long non-weightbearing with a cast, which should start immediately after the diagnosis. The prerequisites of successful reconstructive surgery are correct timing, adequate fixation and a long postoperative non-weightbearing period. In the resolution stage most Charcot foot patients need custom-molded footwear.
