Risk Factors for Lower Limb Amputations in Diabetic Patients
Background: Diabetes mellitus is a major health problem. Diabetic foot problems are a
major complication that can lead to amputation.
Objectives: This study assess the risk factors for lower limb amputation in patients with
"diabetic foot" namely ulcer and infection.
Methods: The study performed from January 2011 till January 2014 in Al-Yarmouk
teaching hospital, Baghdad, Iraq. A cross-sectional study of a sample of 165 diabetic
patients (type 2) who admitted to the hospital with diabetic foot. Patients are cases of
complicated diabetes mellitus who had been admitted in the surgical department because
of diabetic foot complication including ulceration and infection. Statistical analysis was
performed using Chi- square test and independent sample t test. A P-value less than 0.05
was considered statistically significant.
Results: Among 165 patients there were 123(74.5%) males and 42(25%) females. The
mean age was (52.21 ± 8.31) years. The prevalence of amputation within the sample was
126(76.3%), from those amputated patients 30 (23.8%) had minor amputation (toe
amputation and forefoot and metatarsal amputation), 74(58.7%) below knee and
22(17.4%) above knee amputations.
Conclusion: Infection, ulcer and history of previous ulcer and/or amputation are the main
risk factors for lower limb amputation in diabetic patients.
