Spinal fusion device with porous material

摘要

An implant for insertion into at least one bore formed between opposing vertebrae of a spine where the vertebrae are separated by a space and each vertebrae has end plates. The implant is in the shape of a solid generally cylindrical body having a first and a second end, an outer surface, opposing sides and a longitudinal axis. The body has threads on a portion of the outer surface between the first and second ends with the threads being configured for threading into bone. The body includes at least two indentations on its outer surface with the indentations having a surface with each indentation containing a bone attachment material for the attachment of bone to the bone attachment material within the indentations. Each of the indentations are positioned on generally opposing sides of the body so as to provide contact with the end plates of the opposing vertebrae when the implant is inserted into at least one bore formed between the opposing vertebrae.
