DEVICE FOR ESTABLISHING AN ANATOMICAL REFERENCE POINT OF AN INTERVERTEBRAL DISC

摘要

The invention relates to a device (1) for establishing an anatomical reference point of an intervertebral disc (100) for the attachment of at least one instrument intended for the implantation, through a posterior or posterolateral approach, of a disc prosthesis or osteosynthesis cage as a replacement for the intervertebral disc. The device (1) comprises at least two means for bone anchorage (2, 3) each intended to be attached to a vertebra (10) adjacent to the disc (100), a coupling element (11) for the instrument and elements (4) for adjusting the position of the coupling element (11) relative to the position of the disc (100).
