eight-plate
A figure-eight shaped implant used in guided growth procedures to temporarily restrict growth on one side of a growth plate.
Full Definition
An eight-plate is a specialized orthopedic implant designed for guided growth procedures in pediatric patients. The device's distinctive figure-eight shape allows it to be placed across a growth plate using two screws, creating a tension band effect that temporarily restricts growth on the treated side. Unlike traditional staples, eight-plates are designed to allow controlled motion and can be easily removed once the desired correction is achieved. They are commonly used to treat angular deformities such as genu valgum and genu varum in growing children.
Usage
Usage note: Should be hyphenated when used as an adjective (eight-plate system) but not when used as a noun.
