Bone supporting devices with bio-absorbable end members

摘要

A device for supporting adjacent bony portions includes a body having a first end and an opposite second end. The body is positionable in a space between the adjacent bony portions with the first and second ends oriented toward respective ones of the adjacent bony portions. At least one of the first and second ends includes bone engaging surfaces. An end member substantially covers the bone engaging surfaces with a bio-absorbable material on at least one end of the body. The end member providing a smooth surface profile to facilitate insertion of the body in the space between the adjacent bony portions.
