Abstract:
An implant for insertion into a bore formed between opposing vertebrae of a spine where the vertebrae are separated by a space and each vertebrae has end plates and bone tissue, the implant comprising:a) a solid generally cylindrical body having a first and a second end, an outer surface, a length measured from the first end to the second end and a longitudinal axis;b) the body having threads on the outer surface between the first and second ends and along a major portion of the length of the body, the threads configured for threading into bone and having a thread diameter that defines the outer diameter of the body along a major portion of its length;c) wherein the body comprises a first substantially rigid material and a second biocompatible porous material, the second biocompatible porous material being disposed on at least opposed surface portions of the outer surface of the body and arranged to substantially contact the end plates of the opposing vertebrae when the body is inserted into the bore formed between the opposing vertebrae;to permit bone tissue of the end plates to chemically bond directly to the outer surface of the body.
