摘要：
An interbody spinal implant, such as a solid-body or composite implant. The implant has at least one integration surface with a roughened surface topography including a repeating pattern, without sharp teeth that risk damage to bone structures, adapted to grip bone through friction generated when the implant is placed between two vertebral endplates and to inhibit migration of the implant. The repeating pattern is formed of at least three at least partially overlapping repeating patterns. The repeating patterns may radiate at a fixed distance from at least one point and may include recesses having a slope of thirty degrees or less relative to the integration surface. Also disclosed are processes of fabricating the integration surfaces.
