Aim: To evaluate the incidence of lower extremity amputation among inpatients with diabetic foot. To assess the risk factors leading to lower extremity amputation in the same patients

Materials and methods: Diabetic foot patients who required admission during the study period were selected and evaluated. Clinical and laboratory analysis was done for all patients and comparison done between those whose treatment included minor or major amputation of lower extremity with those who were managed without amputation.

Result: The study consists of 100 patients of diabetic foot with 77 of them going for major or minor amputation and 23 of them treated without amputation. A detailed analysis between amputated and non-amputated group showed significant difference in the following factors: age, duration of diabetes, HbA1c, Ankle Brachial Index (ABI), Wagner grade of ulcer and history of previous amputation.

Conclusion: Among the many risk factors for diabetic foot, our group of patients had higher significance for duration of diabetes, HbA1c, ABI and history of previous amputation. The identification of specific population based risk factors for diabetic foot syndrome and advocation of preventive measures, patient education and earlier treatment can help prevent significant morbidity and financial burden to the patient.
