Textured surface having micro recesses such that the outer surface overhangs the micro recesses. Embodiments of the textured surface include sharp edges for promoting bone deposition and growth within the micro recesses, protrusions of varying depth from the surface that include overhangs, and micro recesses that are at least partially defined by complex ellipsoids.

Method for making a mesh-and-plate surgical implant includes the steps of applying maskant to first and second faces of a metal sheet, selectively ablating the maskant on both faces, affixing a first tape to the first face to cover same and maskant thereon, but leaving an exposed portion for a screw hole, affixing a second tape to the second face to cover same and maskant thereon, etching the first face screw hole portion to form a crater, removing the first tape, etching the crater and other exposed portions of the first face, removing the second tape, etching opposite the crater and other exposed portions of the second face to provide openings in communication with the crater, and other second face openings extending to the first face, and removing remaining maskant to provide the implant configured to include a pliable mesh portion and a rigid plate portion, and having a screw hole therein.
