Mid-foot charcot arthropathy in diabetic patients: complication of an epidemic disease

OBJECTIVES: To outline the epidemiological profile of diabetic patients with Charcot arthropathy affecting the midfoot alone or extending from the midfoot to the hindfoot; To assess the results from the treatment that these patients undergo, according to a preestablished protocol, over the medium term. METHODS: We retrospectively evaluated 88 patients (110 extremities) with Charcot arthropathy of the midfoot. The minimum follow-up period was 12 months. We included 45 patients with Charcot arthropathy affecting the tarsal-metatarsal joints (51%); 20 patients in whom the talonavicular, calcaneocuboid and subtalar joints were affected (23%); and 23 patients in whom both the midfoot and hindfoot were affected (26%), as described by Brodsky and Trepman. We defined the treatment as successful when a functional foot was preserved; and unsuccessful when the foot was amputated. RESULTS: From treating Charcot arthropathy primarily involving the midfoot were satisfactory in the cases of 75 patients (85%) treated according to our protocol. For the patients with severe lesions affecting both the midfoot and the hindfoot, a greater number of complex operations (i.e. arthrodesis) were needed in order to obtain the same overall rate of satisfactory results. The osteoarticular lesions originating in the midfoot probably extended progressively to the hindfoot because of delayed diagnosis with inadequate early treatment. CONCLUSION: It was possible to preserve a functional extremity in 85% of the patients. Severe lesions involving the midfoot and extending to the hindfoot required a greater number of surgical procedures to treat them.
