Abstract: An intervertebral implant includes a core member operably coupled between an upper and a lower base member. An outer cavity extends between the core member upper end and lower end, and radially between the inner cavity and an outer surface of the core member. A core member inner wall is formed between the inner and an outer cavity, and a core member outer wall is formed between the outer cavity and the outer surface of the core member. A first locking member is positioned on at least one of the core member upper end and the core member lower end and at least one second locking member is positioned on an inner surface of at least one of the upper and lower base member for locking engagement. The upper and lower end of the core member are oriented at a lordotic angle ranging from 1 degrees to 20 degrees.

Abstract: An intervertebral implant comprising a core member operably coupled between an upper base member and a lower base member, and a core spacer positioned within an inner cavity of the core member. An outer cavity extends between the core member upper end and lower end, and radially between the inner cavity and an outer surface of the core member. A core member inner wall is formed between the inner cavity and the outer cavity, and a core member outer wall is formed between the outer cavity and the outer surface of the core member. At least one first locking member is positioned on at least one of the core member upper end and the core member lower end and at least one second locking member is positioned on an inner surface of at least one of the upper base member and the lower base member for locking engagement.
