    • A method and tool for creating a location for a fixation device to be secured to a bone. The method includes bringing a bone cutting tool extending along a longitudinal axis into engagement with an outer surface of the bone. The bone cutting tool is rotated about the longitudinal axis while driving it from the outer surface of the bone to a predetermined depth in the bone to form a bore. The bone cutting tool is then continuously rotated at the predetermined depth to establish an enlarged bone pocket at a distal end of the bore. The bone pocket defines a shoulder extending around a circumference between the bone pocket and bore. The bone cutting tool is removed from the bone pocket and bore. The fixation device is then inserted into the bone pocket through the bore, where it is seated against the bone pocket shoulder.
    • 一种用于创建用于固定到骨骼的固定装置的位置的方法和工具。 该方法包括使沿着纵向轴线延伸的骨切割工具与骨的外表面接合。 骨切割工具围绕纵向轴线旋转,同时将其从骨的外表面驱动到骨中的预定深度以形成孔。 骨切割工具然后以预定深度连续旋转,以在孔的远端处建立扩大的骨袋。 骨袋包括围绕骨袋和孔之间的圆周延伸的肩部。 骨切割工具从骨袋和孔中取出。 然后将固定装置通过孔插入到骨袋中,其中它被靠在骨袋肩部上。
