A revisable intervertebral implant may include two end plates designed to detachably receive a variety of intermediate components including articulating bearing inserts, elastic inserts, and fusion blocks. Each intermediate component may be secured to a snap insert that snaps into engagement with the corresponding end plate in response to pressure urging the intermediate component toward the end plate along a cephalad-caudal direction. The end plates may first be secured to the corresponding vertebral bodies, and then the intermediate component(s) may be snapped into locking engagement with the implanted end plates to complete in-situ assembly of the intervertebral implant. The implant may easily be revised by snapping the intermediate component(s) out of engagement with the end plates, removing the intermediate component(s), inserting the new intermediate component(s) into the space between the end plates, and snapping the new intermediate component(s) into engagement with the end plates.
