1. An intervertebral implant comprising:
a body having an open lattice structure formed by a plurality of elongate struts, including a first strut and a second strut;
the first strut having a first longitudinal length and a first lateral width, the first longitudinal length being longer than the first lateral width;
the second strut having a second longitudinal length and a second lateral width, the second longitudinal length being longer than the second lateral width;
the body including a contact surface configured to confront a bone plate;
the contact surface including a node defined by an intersection of the first strut and the second strut;
wherein the implant includes an enlarged contact member disposed at the node defined by the intersection of the first strut and the second strut;
wherein the enlarged contact member has a substantially flattened outer-facing surface forming part of the contact surface;
wherein the enlarged contact member has an outer perimeter edge that extends beyond the node defined by the intersection of the first strut and the second strut; and
wherein at least a portion of the first strut and at least a portion of the second strut extend inward from the enlarged contact member toward a central core of the body.
