The present invention provides an intervertebral implant for replacing intervertebral disc material and controlling relative motion between adjacent vertebral bodies. The intervertebral implant may have at least one end plate and an intermediate component which slides into engagement with the end plate. The intermediate component may be engageable with the end plate from an anterior approach, or a right or left lateral approach. The intermediate component can be a set of bearing surfaces which articulate to provide relative motion between two vertebral bodies, an elastic insert which deforms to provide motion between two vertebral bodies, or a rigid insert which prevents relative motion between two vertebral bodies. The intermediate component is replaceable with a different intermediate component which provides a different function. The present invention also provides one or more retaining members which snap into engagement with the end plate and secure the intermediate component to the end plate.

An implant system provides motion preservation or stabilization between two spinal vertebrae. An associated instrumentation system is capable of delivering and removing the implants from either the anterior, left lateral or right lateral positions. The instrumentation system also provides instrumentation for delivering the implant end plates into the disc space, adjusting the position of the end plates in situ, compressing end plates into the vertebral bodies, interoperatively determining the height and angulation of bearings, delivering bearings together and then independently connecting them to the end plates. The system provides alternative instrumentation for revising the motion preservation disc from at least three directions. The system further provides alternative instrumentation for converting the motion preservation disc system to an interbody fusion device from at least three directions.

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.
