摘要： This present invention relates to interbody spinal implants and methods of using such implants. Certain embodiments of the present invention are particularly suitable for placement using an anterior surgical approach. Certain embodiments of the present invention include a body having a top surface, a bottom surface, opposing lateral sides, and opposing anterior and posterior portions. Interbody spinal implants, as now taught, further include roughened surface topography on at least a portion of its top surface and/or bottom surface. Preferred embodiments of the interbody spinal implant are substantially hollow and have a generally oval-shaped transverse cross-sectional area. Preferred embodiments of further include at least one aperture that extends the entire height of the implant body. This vertical aperture also defines a transverse rim having greater posterior thickness than anterior thickness. Certain embodiments also preferably include at least one aperture that extends the entire transverse length of the implant body.
