Abstract

This invention relates to an intervertebral spacer with four variants of combination of the parts invented, for fitting in the spinal column of a person when there is a need to replace the intervertebral disc. It is composed of two units articulated together so as to maintain the interdisc space and to allow the mobility of the vertebral bodies adjacent to it. The upper unit has a horizontal plate for insertion into the disc space with a hemisphere in the lower part and a vertical part with a plate for fixing by means of screws to the vertebral body above. The lower unit has a horizontal box structure for insertion into the disc space, containing, inside, a high- density polyethylene part, which has a hemispherical cavity for articulation with the hemisphere of the upper part. This unit also has a vertical plate for fixing by means of screws to the vertebral body below.
