1. A spinal implant comprising:
a body extending from an upper surface to a lower surface, the body having an anterior end, a posterior end and spaced apart medial and lateral side walls extending between the anterior and posterior ends such that a single internal chamber free of any implant structure is defined within the anterior and posterior ends and the medial and lateral walls, the body defining an outer perimeter and an inner perimeter extending about the internal chamber,
wherein the body includes a solid support structure having an upper solid structure extending along the upper surface and at least in part coplanar with the upper surface and a lower solid structure extending along the lower surface and at least in part coplanar with the lower surface, the solid support structure further having a porous structure disposed between the upper and lower solid structures and extending from the outer perimeter to the inner perimeter,
wherein the upper solid structure includes an outer rim and an inner rim, and the lower solid structure includes an outer rim and an inner rim, at least a portion of the inner rims of the upper and lower solid structures in contact with the single internal chamber,
wherein the solid support structure includes at least one solid strut extending between the upper solid structure and the lower solid structure, the at least one solid strut extending from the inner rim of one of the upper or lower solid structures to the outer rim of the other of the upper or lower solid structures, and
wherein the porous structure at least partially encapsulates the at least one solid strut.
