ABSTRACT:
Embodiments of instrumentation and methods are provided for the insertion of intervertebral disc prosthesis. The instrumentation of the embodiments comprises a guide comprising at least two lateral faces, at least one upper plate, at least one lower plate, at least one retainer, a cage defining an insertion axis for the prosthesis, and an angle adjuster adapted to adjust an angle formed by the insertion axis and an antero-posterior sagittal axis; and at least one separator sized to maintain a gap between the upper vertebra and the lower vertebra. Methods for implanting a prosthesis using the disclosed instrumentation comprise implanting a pin in the median sagittal axis of a vertebrae; measuring the dimensions of the intervertebral space; choosing the prosthesis; choosing the guide; adjusting the angle adjuster; positioning the guide adjacent to the intervertebral space; inserting the prosthesis into the guide; and inserting the prosthesis into the intervertebral space.
