Abstract
An interbody spinal implant and a process of producing the implant. The implant includes an integration surface having a roughened surface topography as at least part of the top surface, bottom surface, or both surfaces. The integration surface comprises at least one or more of (a) a plurality of grains; (b) intergranular boundaries between the plurality of grains; and (c) unsatisfied chemical bonds. The integration surface may be produced by texturing a surface by chemical processes, mechanical processes, or both to provide the plurality of grains and intergranular boundaries and chemically etching the surface to provide unsatisfied chemical bonds. In addition, the plurality of grains and the intergranular boundaries may etch at different or non-uniform etch rates.
