In the clinic, implant-associated infections are the chief risk facing orthopaedics and traumatology departments. Vancomycin-poly(D,L)-lactic acid (PDLLA) loaded plates were prepared by using solvent casting technology. The bacteriostatic activity to Staphylococcus aureus was evaluated in vitro. The biocompatibility of the plates was investigated by acute systemic toxicity test, haemolytic test, cytotoxicity test, etc. The in vitro inhibition test of Staphylococcus aureus showed that the plates had an inhibitory effect on Staphylococcus aureus. There was no toxicity for the vancomycin-PDLLA loaded plates. There was a good biocompatibility for the vancomycin-PDLLA loaded plates. These findings indicate that the plate maybe used to prevent or cure infection.
