Abstract

A method for implanting an implant into a bore formed between opposing vertebra includes forming a bore between the vertebra and selecting an implant having a rigid body with exposed threads and a hollow interior and with holes formed through a shell of the body into the interior. The implant is placed within the bore with a longitudinal axis of the body aligned with an axis of the bore. The body is advanced into the bore to stretch an annulus.
