The increase in total hip arthroplasty occurs by many factors, such as increasing life expectancy, improving surgical technique as well as innovating the design and implant material. However, despite technological advances, peri-prosthetic infection has remained one of the most devastating complications. This study evaluates the prophylactic application of calcium sulfate pearls medicated in the femoral canal and acetabular surface to prevent peri-prosthetic infections in patients who underwent total uncemented primary hip arthroplasty against a control group by measuring acute phase reactants. 146 patients, 67 were applied calcium sulfate pearls medicated and 79 prophylactic antibiotic intravenous in the period from 2013 to 2016. To perform the diagnosis of peri-prosthetic infection was assessed PCR associated with VSG, communication between fistula and prostheses and positive culture in 2 or more different sites. There was a decrease in the values of acute-phase reactants in patients who were given calcium sulfate pearls. 14 patients presented infection in the control group and 3 in the study group. The prophylactic use of calcium sulphate pearls within the medullary canal and acetabular surface is an option for the prophylaxis of peri-prosthetic infections, however the study deserves follow-up with more patients.
