Abstract
An intervertebral implant includes a body formed as an open lattice structure by a plurality of struts. Some of the struts of the plurality of struts intersect at nodes. The nodes can include an enlarged contact member that extends over the node and at least a portion of the width of some of the struts. Enlarged contact members may have an asymmetrical shape with respect to the intersection of struts. The enlarged contact members can provide improved bone contact for the implant. The plurality of struts can have a cross-sectional shape that includes a flattened portion. The flattened portion of the plurality of struts can provide improved bone contact for the implant. An additive manufacturing process can be used to build the implant in a substantially vertical direction.
