Long-term survival and favourable outcome of implant use are determined by bone-implant osseointegration and absence of infection near the implants. As with most diseases, prevention is the preferred approach. Silver ion doped calcium phosphate based ceramic coating (Silveron®) for implant coating has been shown previously to be a potent antimicrobial agent as indicated by in vitro testing. The present study reports on clinical experience using silver ion doped calcium phosphate based ceramic coated external fixator pins as surgical treatment in the management of chronic osteomyelitis and open fractures. Ten patients had external fixators: six for open fractures of ankle, three for chronic osteomyelitis of the femur, one for tibia pseudoarthrosis. The electrospray method was used for coating the external fixator pins with silver ion doped calcium phosphate-based ceramics. A radiofrequency energy source was used to sinter the coated pins. Microbiological, roentgenographic, toxic and biochemical analyzes of patients were carried out. Wound debridement, and subsequent wound care resulted in control of the infection in three chronic osteomyelitis and in healing of seven fractures after follow-up ranging from three to six months. In total 67 pins were used in 10 patients but only one pin was positive microbiologically in one patient. Collectively, these data clearly illustrate that the toxic effects of silver were not observed at the doses used. Silver ion doped calcium phosphate based ceramic coating (Silveron®) can be used to prevent infection associated with the implant.
