摘要:
A method of producing an interbody spinal implant. The method includes the steps of obtaining a blank having a top surface, bottom surface, opposing lateral sides, and opposing anterior and posterior portions, and applying a subtractive process (e.g., masked acid etching) to the top surface, the bottom surface, or both surfaces of the blank to form a roughened surface topography. Subsequently, the blank is machined to form the interbody spinal implant, which includes a body having a top surface, a bottom surface, opposing lateral sides, opposing anterior and posterior portions, a substantially hollow center, and a single vertical aperture where the top surface, the bottom surface, or both surfaces of the interbody spinal implant have the roughened surface topography produced by the subtractive process. This simplified method produces more accurate and repeatable implants with fewer process steps and defects, reducing process time and costs.
