Abstract: A stand-alone ALIF implant that comprises a cage and a rotatable plate attached to an anterior portion of the cage by a fastener mechanism. The plate may also be integrally formed with the cage, and both are typically manufactured using additive manufacturing techniques. Support material may be added during the additive manufacturing process to lend support to the implant, and may be positioned around the fastener mechanism during manufacturing of the implant. Once formed, the support material may be dissolved away, thereby allowing the plate to rotate independently from the cage, but still remain movably attached via the fastener mechanism. The cage may further comprise webbing thereon to promote bone growth.

Abstract: A structurally encoded implant comprising a pair of endplates movably secured at the posterior end via a slip joint and a wedge component. The wedge component is inserted between the pair of endplates to increase implant height and change the lordotic angle. The pair of endplates may be manufactured together as one integral component using additive manufacturing techniques. During this additive manufacturing process, water-soluble support material may be positioned around the slip joint. Once the pair of endplates is formed, the support material may be dissolved away, allowing the pair of endplates to move independently from one another, but to still remain movably attached via the slip joint, such that the pair of endplates allow for height expansion and lordotic angle change.
