Why should fixation devices of different metals be avoided during implantation?

To prevent infection
To avoid possible electrolytic reaction
To ensure structural stability
To reduce healing time

The correct answer is: To avoid possible electrolytic reaction

Fixation devices made from different metals should be avoided during implantation primarily to prevent possible electrolytic reactions. When dissimilar metals are placed in contact within the body, an electrochemical reaction can occur, leading to galvanic corrosion. This reaction can compromise the integrity of the metal devices, potentially leading to the release of metal ions into the surrounding tissue, which may increase the risk of adverse reactions, such as inflammation or sensitivity. This concern is particularly relevant in a surgical context, where maintaining the integrity of implants is critical for successful healing and function. Therefore, utilizing fixation devices made from the same or compatible metals is essential for ensuring both biocompatibility and the longevity of the implants.
