An implant ( 10 ) is provided for replacement of an intervertebral disc ( 14 ). The implant 10 includes a core portion ( 20 ) extending into the disc space ( 16 ) and the ligament portion 20 extending longitudinal against the anterior side of the spine ( 12 ). The core portion ( 20 ) is configured to at least partially replicate the function of an intervertebral disc ( 14 ) and the ligament portion ( 22 ) is configured to at least partially replicate the function of an anterior longitudinal ligament ( 28 ). To this end, the core and ligament portions ( 20, 22 ) preferably have different mechanical properties from each other that are customized to provide the particular function desired for each portion ( 20, 22 ).
