A bone plate formed of a fiber-reinforced polymer composite, comprising a radiopaque marker that delineates at least a part of the contour of the plate. In some embodiments, the radiopaque marker comprises a metal wire section embedded proximal to an edge of the contour, for example at a distance of 1 mm from an edge of the contour. In some embodiments, the radiopaque marker extends along a head portion of the plate, and/or along a stem portion of the plate. In some embodiments, the metal wire is formed as an intermittent line. Alternatively, the wire is formed as a continuous line.
