Abstract

Abstract One embodiment of a spinal spacer (10) includes a body (11) sized and configured for engagement between adjacent vertebrae (V). The body (11) includes two opposite faces (12, 14) and an outer surface (13) between the two faces (12, 14). In one embodiment, the body (11) includes deactivated bone material in synergistic combination with a bone growth factor. A sleeve (15) is disposed around the outer surface (13) of the body (11). The sleeve (15) is composed of a second material which is relatively stronger under compressive loads than the biocompatible material of the body (11). Also provided is a plurality of apertures (16) through the sleeve (15) in communication with the outer surface (13) of the body (11) for bone ingrowth. Means for attaching the sleeve to the endplates of adjoining vertebral bodies are also provided.
