What should be avoided to prevent electrolytic reaction in fixation devices?

The choice to avoid mixing metal fixation devices is rooted in the principles of galvanic corrosion, which can occur when two dissimilar metals are in electrical contact with each other in the presence of an electrolyte. Different metals have varying electrochemical potentials, and when contacted, the less noble metal can corrode preferentially, leading to device failure. In surgical settings, fixation devices such as screws, plates, or rods that are made of different metals can create this electrolytic reaction, compromising the integrity of the implant and possibly leading to complications.

Using renewable energy sources, applying excessive pressure to materials, or choosing to use ceramic materials exclusively do not directly address the issue of electrolytic reactions in metal fixation devices. Each of these factors may impact other aspects of surgical practice or material selection but does not specifically mitigate the risk associated with mixed metal implantation. Therefore, to ensure the longevity and functionality of fixation devices, it is crucial to use materials that are compatible and avoid mixing metals.
