<p>A device (10, 110, 210, 310, 410, 510, 610) for supporting adjacent bony portions includes a body (11, 111, 211, 311, 411, 511, 611) having a first end (12, 212) and an opposite second end (13, 213.) The body (11, 111, 211, 311, 411, 511, 611) is positionable in a space between the adjacent bony portions with the first and second ends (12, 212, 13, 213) oriented toward respective ones of the adjacent bony portions. At least one of the first and second ends (12, 212, 13, 213) includes bone engaging surfaces (40, 50.) An end member (80, 90, 180, 282, 284, 380, 480, 580, 680, 780) substantially covers the bone engaging surfaces (40, 50) with a bio-absorbable material on at least one end of the body (11, 111, 211, 311, 411, 511, 611.) The end member (80, 90, 180, 282, 284, 380, 480, 580, 680, 780) provides a smooth surface profile to facilitate insertion of the body (11, 111, 211, 311, 411, 511, 611) in the space between the adjacent bony portions.</p> |
