US Patent 11058552 Anterior lumbar interbody fusion cage and plate

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.
