This is an epidemiological non concurrent cohort study on surgical site infections after hip arthroplasties, based on the information contained in 305 records of patients operated at the "Santa Casa de Belo Horizonte" Hospital. The goals were to determine the incidence rates of surgical site infection in patients, aiming at verifying the association between the surgical site infection and some risk factors and at identifying the time for the manifestation of surgical site infection and the microorganisms involved. The prevalent microorganism was the Staphylococcus aureus. A 8,5% accumulated incidence rate of surgical site infection was found. The risks factors associated to infection were patient's clinical condition (ASA); pre and post-operative hospitalization time; type of surgical procedure; anesthesia and hospitalization unit.
