摘要：
Interbody spinal implants comprise internal sidewalls having a roughened surface topography. The internal sidewalls may be those that surround a substantially hollow implant center, including the sidewalls of a vertical aperture and sidewalls of a transverse aperture. The roughened surface topography comprises macro, micro, and nano features that comprise an amplitude, a peak to valley height, and spacing.
