Background: Any operation is exposed to infection. The need for antimicrobial prophylaxis in orthopedic surgery for acute or elective surgical cases of clean surgery is established as a routine procedure. Orthopedic Surgery when required the use of metallic implants in order to perform internal fixation or replacement of the articular surfaces, increases the risk of infection because they are foreign materials are introduced into the body. In these cases, preventive antibiotic therapy is very important. Materials and methods: We performed a study of antimicrobial prophylaxis multicenter, randomized, prospective, double-blind, parallel group comparison in order to evaluate the effectiveness of Cefadroxil IV vs. Cefazolin I.V. as prophylactic antibiotics by determining the number of infected patients after fracture surgery in which synthetic material was placed. Results: Fifty eigth patients were completed, 34 in the cefadroxil group and 24 in the cefazolin group, at the beginning the groups were similar in age, sex, fracture type, operative time, time between fracture and surgery. More patients in the cefadroxil group had the maximum allo-wable time between the fracture and surgery. (P: 0.07). In the cefadroxil group we found a wound infection and one case of mild erythema which resolved with oral treatment with cefadroxil, without differences between groups. There were three cases of adverse events, anaphylactic reaction to cefazolin at 48 h in the group that required finalization of protocol and hematoma in right leg and in the cefadroxil group, a moderate increase in liver enzymes. Conclusions: The therapeutic response of antimicrobial prophylaxis showed no difference between groups. Cefadroxil is as effective as cefazolin for antimicrobial prophylaxis in patients with fractures that warrant placement of synthetic material.
