摘要:
A composite interbody spinal implant including a body having a top surface, a bottom surface, opposing lateral sides, and opposing anterior and posterior portions; a first integration plate affixed to the top surface of the body; and an optional second integration plate affixed to the bottom surface of the body. At least a portion of the first integration plate, optional second integration plate, or both has a roughened surface topography including macro features, micro features, and nano features, without sharp teeth that risk damage to bone structures, adapted to grip bone through friction, inhibit migration of the implant, and promote bone growth. Also disclosed are processes of fabricating a roughened surface topography, which may include separate and sequential macro processing, micro processing, and nano processing steps.
