Metallosis on Tissues and Serum Metal Levels in Children


About this study

Slightly elevated blood metal levels have been found in adults undergoing hip and knee replacement. It is unknown whether pediatric patients with metal implant(plates/screws/rods) have elevated blood metal levels. This may have an impact on practice if children have high blood metal levels with routine orthopedic implants. If researchers find elevated metal levels, they may recommend patients to have the plates removed or may switch to a different type of metal. Further work on this topic is needed.
