OBJECTIVE: To determine the frequency of minor and major amputations in diabetic patients at different Wagner s grades of severity and to correlate it with the glycaemic control. DESIGN: Cross-sectional analytical study. PLACE AND DURATION OF STUDY: Department of Orthopedic Surgery, Jinnah Postgraduate Medical Centre, Karachi, over a period of 3 years from August 1999 to August 2002. SUBJECTS AND METHODS: The study included 60 patients of diabetic foot disease, who were distributed in to six grades of severity according to the Wagner s method. Glycaemic control was determined by baseline fasting and random blood sugar and HbA1c levels. Patients were treated accordingly and followed-up. Frequencies of minor and major amputations were found and these were correlated with the glycemic control of the patients. RESULTS: There was no patient in grade-0, 6 (10%) patients in grade-I, 13 (21.6%) in grade-II, 14 (23.3%) in grade-III, 18 (30%) in grade-IV and 9 (15%) patients in grade-V respectively. Thirty-seven (61.6%) patients were male. The mean age of the patients was 50.88 +/- 11.06 years. In 40 (66.7%) patients, the duration of diabetes was 8 years or longer. Fifty six (93.3%) were having NIDDM and 35 (58.3%) were smokers. Staphylococcus aureus was the most common pathogen isolated from the wound. Only 1 (16.6%) patient in grade I underwent minor amputation, while 3 (23.7%), 8 (57.14%) and 8 (44.44%) underwent minor amputation in grades II, III and IV respectively. Three (21.42%), 10 (55.55%) and all 9 (100%) underwent major amputation in grade III, IV and V respectively. Below-the-knee amputation was the most commonly performed procedure. Overall frequency of minor and major amputation were 20 (33.3%) and 22 (36.3%) respectively. Patients with poor glycaemic control had higher percentage of minor and major amputation (p-value = 0.001). CONCLUSION: The frequency of minor and major amputation increases with the higher grades of diabetic foot. Poor glycaemic control is a significant risk factor for amputation in diabetic foot patients.
