The global prevalence of diabetes mellitus is increasing substantially. This overall increment leads to the growth in the number of individuals with diabetic complications including peripheral arterial disease and lower extremity amputation. In low-income countries like Sierra Leone, the lack of access to adequate health care, poverty and social stigma attached to the term "Amputation" all prevent people from seeking early medical treatment for diabetic foot lesions. The purpose of this study was to establish and document the causes, risk factors, indications and complications of lower limb amputations and to make appropriate recommendations to the health sector of Sierra Leone for it prevention.This retrospective study was conducted at 34 Military Hospital, one of the major referral hospitals in Freetown, between January 2011 and December 2014. A team of medical staff was trained. The operating theatre records, anesthetists' books and ward case notes were searched for information of all the patients who underwent amputation during period under review. The findings were statistically documented in tables.Twenty-seven (27) patients were involved in the study. There were 24 males and 3 females. The age distribution was 15-65 (Mean 43 years). Majority (77.7%) of the patients presented with gangrenous and infected diabetic feet, 18.5 % was due to Road Traffic Accident and 3.8% due to complication of HIV infection. The commonest procedure was transtibial amputation (85%) and (67%) was on the right side. Hospital stay was 20-50 days (35 days). There was no postoperative mortality.As most amputations were done for diabetic feet, there is a need for diabetes sensitization and prevention campaigns for the general public and improvement of diabetic care for individual patients including proper glycemic control and risk factors prevention. Prevention of road traffic accidents by training of drivers and motorbike riders should also be considered. Increased funding is needed by the health sector of Sierra Leone to implement these measures.
