MILLING INSTRUMENTATION HAVING FIRST AND SECOND TRACKS FOR PREPARING A SPACE BETWEEN ADJACENT VERTEBRAL BODIES

摘要

An apparatus and method for placing adjacent vertebrae at afixed distance and angular relationship relative to each other,fixing the vertebrae in the position by use of a milling block(100) engaging each of the adjacent vertebrae, and then using amilling instrument (200), the depth, length and excursion ofwhich from side to side are controlled by the apparatus tomachine out a defined thickness of bone and a space of definedlength, height, width and shape in preparation for receiving aninter-body spinal implant of graft or known size and configuration,are disclosed.
