The effects of silver coated external fixation pins.

We performed a randomized controlled trial in order to assess the effect silver coating of an external fixator pin has on pin infection. The experimental silver coated pins (SC) were compared to control stainless steel (SS) pins. A clamp design monolateral fixator was used, and pins were randomized to clamp position to allow side-by-side comparisons of pins in a similar environment. Nineteen patients and 33 clamps were entered and completed the study. There were no significant differences between the two types of pins in the rate of pin tract infection, clinical appearances of the pin sites, bacteriology of the pin tracts, torque to remove the pins, or radiographic lucency around the pin. We concluded that with the numbers available in this study, there were no detectable differences between the performance of SC and SS pins.
