    摘要: A posterior arch prosthesis according to the present invention includes a main body, two transverse protuberances extending transversely from either side of the main body, articulating surfaces formed on each of the transverse protuberances, and a posterior protuberance extending posteriorly from the main body. The posterior protuberance is attached to a first vertebra from which the natural posterior arch has been removed such that the articulating surfaces are arranged in articulating contact with surfaces on an adjacent, second vertebra. The posterior protuberance includes an attachment to which native structure may be reattached upon attachment of the prosthesis to the first vertebra.
