Background/aim: We evaluated the existing risk factors with clinical results in patients who underwent major and minor amputation of the lower extremity as a result of diabetic foot ulcers (DFUs). Materials and methods: We retrospectively studied 107 patients who had undergone lower extremity amputation. The patients were divided into minor (Group 1, n = 75) and major (Group 2, n = 32) amputation groups. On clinical evaluation, the type of surgery performed, smoking history, comorbidities, duration of diabetes mellitus (DM) diagnosis, duration of DFU presence, peripheral neuropathy, peripheral arterial disease, results of deep tissue culture, length of hospitalization, and blood parameters were investigated. Results: In Group 2, mean hospitalization time was significantly longer than in Group 1 (P < 0.05). The proportion of patients with Wagner Grade 4 was significantly higher in Group 2 than in Group 1 (P < 0.05). The duration of DM and DFU was significantly longer in Group 2 (P < 0.05). The number of polymicrobial agents was significantly higher in Group 1 (P < 0.05). Conclusion: In our study, the most important risk factors that led to major amputation in patients with DFU were age, Wagner classification, duration of DM, duration of DFU, and C-reactive protein level.
