SPINAL IMPLANT HAVING A PASSAGE OF ENHANCING CONTACT BETWEEN BONE GRAFT MATERIAL AND CORTICAL ENDPLATE BONE

摘要

An interbody spinal implant (1) including a body having a top surface (10), a bottom surface (20), opposing lateral sides (30), opposing anterior and posterior portions (40,50), and a substantially hollow center in communication with a vertical aperture (60), which are filled with a bone graft material. The dimensions, shape, and position of the vertical aperture (60) facilitate contact between the bone graft material and vertebral endplate bone to support and enhance bone growth.
