Antibiotic-Loaded Cement in Orthopedic Surgery A Review
Infections in orthopaedic surgery are a serious issue. Antibiotic-loaded bone cement was developed for the treatment of infected joint arthroplasties and for prophylaxes in total joint replacement in selected cases. Despite the widespread use of the antibiotic-loaded bone cement in orthopedics many issues are still unclear or controversial bacterial adhesion and antibiotic resistance
