Abstract

The purpose of the present retrospective study was to evaluate the outcomes (ie, ulcer recurrence, major amputation, death) in diabetic patients undergoing Chopart amputation because of deep infection or gangrene extending to the midfoot. From 2009 to 2011, 83 patients, aged 71.4 ± 9.3 years, underwent a midtarsal amputation and were followed up until December 31, 2012 (mean follow-up 2.8 ± 0.8 years). Of the 83 patients, 26 were female, 61 required insulin, 47 had renal insufficiency, 19 underwent hemodialysis, 65 had hypertension, 34 had a history of cardiac disease, and 4 had a history of stroke. Chopart amputation was performed in 38 patients (45.8%) with gangrene, 31 (37.4%) with abscess, and 14 (16.9%) with osteomyelitis. Urgent surgery was performed in 56 patients (67.5%). Effective revascularization was performed in 64 patients (77.1%) patients. Of the 83 patients, 47 had healed at a mean period of 164.7 (range 11 to 698) days. Ulcer recurrence developed in 15 patients (31.9%). A major amputation was necessary in 23 patients (27.7%), with an annual incidence of 13.0%. None of the included variables on logistic regression analysis was significantly associated with proximal amputation. Of the 83 patients, 38 (45.8%) died, with an annual incidence of 25.8%. On logistic regression analysis, age (odds ratio [OR] 1.11, 95% confidence interval [CI] 1.01 to 1.16), history of stroke (OR 9.94, 95% CI 3.16 to 31.24), and urgent surgery (OR 2.60, 95% CI 1.14 to 5.93) were associated with mortality. Chopart amputation represents the last chance to avoid major amputation for diabetic patients with serious foot complications. Our success rate was great enough to consider Chopart amputation a viable option for limb salvage in this high-risk population.
