摘要：
An intervertebral implant and associated method. The intervertebral implant can include a first component having a first articulating surface and a first bone engagement surface for engaging a first vertebra, and a second component having a second articulating surface and a second bone engagement surface for engaging a second vertebra adjacent to the first vertebra. The first and second articulating surfaces articulate with each other for substantially replicating a natural spinal movement. The first and second bone engagement surfaces define an outer surface substantially shaped as an envelope of five cylinders.
