Abstract
A spinal spacer for engagement between vertebrae includes a body having a substantially contoured first end surface at a distal end and a second end surface opposite thereto at a proximal end. The body extends between the first and second end surfaces to define top and bottom vertebral engaging surfaces that are opposed to one another. The body extends between the top and bottom vertebral engaging surfaces to define opposed side surfaces. The top and bottom vertebral engaging surfaces intersect with the side surfaces to provide a substantially quadrilateral cross-section with rounded corners. The top and bottom vertebral engaging surfaces have a substantially streamlined convex profile. The surfaces converge at the distal end to define a substantially atraumatic blunt nose having a tip configured with planar and/or convex surfaces.
