Implant-related osteomyelitis is common in orthopedics. Absorbable antibiotic-loaded calcium sulfate (ACS) is an alternative to nonabsorbable antibiotic depot options for osteomyelitis and fracture-related infections. This study aims to evaluate intramedullary canal filling and coating characteristics of ACS around tibial nails using a tibia SAWBONES model. This research was done to better understand the potential utility of ACS in situations requiring fixation in the setting of local infection.
