Abstract
An implant includes a first body member and a second body member connected by a plurality of bone contacting elements. Some of the bone contacting elements may have a generally helical geometry. Some of the bone contacting elements may have an undulating planar geometry. The bone contacting elements may have a rounded cross-sectional shape or a rectangular cross-sectional shape.
