Abstract :

Introduction. Pin tract infection is a common complication in fracture cases treated with stainless steel external fixation pin. Silver has an antimicrobial effect which effectively address bacteria that contaminate and infect wound. By the same principles, researcher used a external fixator pin that had been overlaid with silver ion and assess the effectiveness of using silver (silver coated pin) on pin tract infection cases

Material and methods. This study is an experimental laboratory research with complete randomized design with repeated observation. The research subjects were adult male rabbits that met the inclusion criteria. Consecutive sampling method was performed on 2 group, each of them consist of 10 rabbits. Group A (control) : we perform installation of stainless steel external fixation in the left tibia of each research subject, Group B (Experiment) : we perform installation of silver coated external fixation in the left tibia of each research subject. We performed inoculation of Staphylococcus aureus bacterial colonies as much as 0,5 MacFarland at the puncture site of external fixation pin. We evaluated the number of the bacterial colonies in puncture site by histopathology, in all research subject at day 7 and 14

Results. The results of the study showed that at day 14, the number of colonies of both group was decreasing, group A (Mean±Std 110.87) and group B (Mean±Std 88.16) with p value of 0.02 (p< 0.05) which means that these result was statistically significant

Conclusion. The results of this study indicate that the usage of silver coated external fixation pin is better to reduce the bacterial colonization and adhesion.
