Abstract
An intervertebral implant for positioning in a lordotic disc space that avoids any unnecessary cutting of bone and therefore, any unwanted subsidence, is provided. Specifically, the implant can work particularly well between the L5-S1 juncture. The implant comprises an inferior component, and a superior component, wherein the superior component has an upper portion and a lower portion, wherein an expandable component is situated between the upper portion and the lower portion, and the implant has a profile that changes from a relatively flat profile to a relatively angled profile. A method for inserting an intervertebral implant into a lordotic intervertebral disc space from a posterior approach without unnecessary bone removal, and without resulting subsidence also is provided.
