Abstract
A series of instruments (30, 80, 120, 210, 510, 550) are provided for direct-anterior and oblique-anterior disc space and end plate preparation. The instruments (30, 80, 120, 210, 510, 550) provide precise guidance for channel formation in the vertebral endplates by guiding rotating and bladed cutting instruments (122, 250, 580). Instrumentation (550) for oblique-anterior disc space preparation includes compound angulation to account for the angle of approach to the spine and the angulation between adjacent vertebrae. Methods and techniques for use of the instruments (30, 80, 120, 210, 510, 550) are also described.
