Abstract
A spinal implant is provided and includes a body portion defining a longitudinal axis. The body portion includes a distal end portion, a proximal end portion, opposed side surfaces that extend between the distal and proximal end portions, and top and bottom surfaces configured and adapted to engage vertebral bodies. The top and bottom surfaces have a surface roughness between 3-4 μm. A cavity extends through the top and bottom surfaces defining a surface area that is at least 25% of a surface area of the top surface or the bottom surface. First orifices are defined through the top surface and second orifices are defined through the bottom surface. The second orifices are connected to the first orifices by a plurality of channel.
