Aims The aim of this study was to compare the outcomes of surgical treatment of osteomyelitis caused by methicillin‐resistant Staphylococcus aureus (MRSA) with cases caused by methicillin‐sensitive Staphylococcus aureus (MSSA). Methods We abstracted data of a series of 185 consecutive patients with diabetes and foot osteomyelitis undergoing surgery within the first 12 h after admission at a single hospital. Bone infection was confirmed by histopathological studies. Only cases where Staphylococcus aureus was isolated from bone specimens were included in this analysis. We analysed several variables between the two groups: MRSA vs. MSSA. Results MRSA bone infection was associated with higher body temperature ( P = 0.02) and white blood cell count ( P = 0.02) than MSSA. Patients with MRSA infections underwent a greater number of surgical procedures ( P = 0.03). Limb salvage was achieved in 93.6% of the patients, with no statistically significant difference in limb salvage rates between MRSA and MSSA‐related osteomyelitis. Conclusions From our experience, where treatment is based on early and aggressive surgical treatment, MRSA bone infections are not associated with worse prognosis.
